Our experts have been strapping on fitness watches of all kinds for close to a decade now, testing more than 50 of the best devices and pulling together the winners for every situation in this guide. Whether you’re a marathoner tracking every BPM or just casually interested in your weekly workouts, there’s something here for you.

These watches have been tested and compared for sensor accuracy, battery life, functionality, durability, and fit. Beyond that, we’ve also taken them everywhere — from the summits of volcanoes in the Pacific Northwest to the depths of the canyonlands of Utah — and pushed these devices to the limit to see what breaks.

If you’re new to fitness tracking and want something to tally up your active minutes, options like the COROS Pace 4 are impressive for the price. Alternatively, we’ve been blown away by the feature density in top-tier watches like the Garmin fenix 8 Solar Sapphire. Whatever your specific needs, read on for the best fitness watches, GPS watches, and fitness trackers based on our testing.

Editor’s Note: We updated our Fitness Watch guide on November 21, 2025, to add the COROS Pace 4, our new best-budget choice that will only run you a cool $250, but packs in a brilliant AMOLED screen, impressive health metrics, and a good bit more for the price.

If you’re looking to track every activity, stretch the limits of wrist-bound battery life, and integrate your fitness watch into your daily routine, the Garmin fenix 8 ($1,100-1,200) is the device to do it with. We’ve worn iterations of the line since we first reviewed the fenix 3, and they’ve only gotten better with every update.

So what’s new on the fenix 8? Plenty. For one, a depth sensor that operates down to 40 m and performs as an EN13319-certified dive computer. There’s also a new speaker and microphone, leaning into the realm of smartwatches and providing access to voice assistants. Finally, the updated solar screen increases battery life by ~25% in the different power profiles.

Besides the new, the 8 brings forward all of the activity tracking profiles we loved about the fenix 7, along with a selection of new ones to bring the total number to an impressive 112. These range from standards like hiking, biking, and skiing to the more niche XC skate skiing, wakeboarding, and table tennis (really). All of these profiles are tweakable, meaning you can change your data screens to suit how you use the information.

The general user interface is also spruced up a bit, and the watch is available in three different bezel sizes: 43, 47, and 51 mm. We put the fenix 8 into the hands of editor Seiji Ishii, a self-proclaimed data dork and exercise physiology graduate who shook it down for 4 months while cycling, rucking, and climbing. “It can do everything, and I mean absolutely everything, with precision, and it has proven durable in doing so,” he reported.

The big question is whether to go with the vibrant AMOLED screen or the solar-charging MIP option. We’re wearing the solar screen for several reasons. For one, the trade-off in recharging is too great to ignore for extended trips outside. Second, the MIP screen will be a more efficient option, even without the added solar cells. It is tough to ignore how good the AMOLED screen looks, however, so if your usage is more day-to-day, give it a look.

Breaking the $1,000 ceiling on fitness watches is a high bar, but we think if any watch is worthy, it’s the fenix 8. If you’re more of a single-activity person, a watch like the Garmin Forerunner 570 may be a wiser choice. But if your weekends take you from the mountains to the shoreline on marathon adventures, a do-it-all option like this is the way to go.

Cory Smith

The newly-released COROS Pace 4 ($249) builds on its budget-friendly predecessor and locks down our recommendation for a spend-wise fitness watch yet again. This new version adds a beautiful AMOLED screen, somehow doesn’t lose out on any battery life for it, and only asks an additional $50 for it.

Editor Andrew McLemore put the Pace through its uh, paces, and found the updated AMOLED screen to be a worthwhile upgrade: “AMOLED displays just look awesome. They make it easier to quickly read and comprehend the complex data that’s now available on all these devices. Getting a better display on the Pace 4 while only raising the price $20 from the previous generation? That’s a pretty good deal,” he said.

The Pace 4 also adds a flashlight function, although it isn’t exactly the same as the built-in LEDs of the Garmin fenix, but instead a full-screen white mode that does provide a decent amount of light, just not as much. The 4 also adds a microphone, along with the ability to add voice memos to things like tracked activities.

Activity tracking is widely varied, with 27 different profiles to choose from, along with daily health stats, HRV monitoring, and REM sleep tracking. You won’t get quite as wide a variety as the brand’s higher-end Apex and Nomad lines, but it’s generally enough for most people to track their health and activity effectively.

The breadcrumb navigation mapping is an obvious budget pinch point, but for many folks who don’t need a map to run around the park, it’s not an issue. If mapping is something you’re after, you’ll need to upgrade to the Pace Pro ($349) or something like the Suunto Vertical ($499). For the money, though, the Pace 4 is everything we need it to be for a budget fitness watch. The older Pace 3 is still available, for you true budget hounds, and will save you $50 to get mostly the same watch.

Read Review: COROS APEX 2 Pro Review: This Sports Watch Sets Benchmark for Battery Life

While other giant-bezel watches can cram in more longevity, when it comes to a watch that is a common-sense size, has all the bells and whistles, and still trudges on with incredible battery life, the COROS Apex 2 Pro ($449) ticks all of our boxes for the best mid-tier fitness watch available today. If you need a bit more functionality than watches like the COROS Pace 4 or Amazfit Cheetah Pro offer, this is the watch to bump up to.

Newly updated, the Apex line from COROS is its middle-of-the-road offering, but you wouldn’t know that from looking at it. Within the 46mm bezel is the full complement of activity tracking profiles, ABC (altimeter, barometer, compass) sensors, and antenna for a newly expanded five Global Navigation Satellite Systems.

Compared to the Apex 2, the Pro version got an extra infusion of satellite tech in the form of a Dual-Frequency chipset, which, during recent testing, we found made a tangible difference in old-growth forests and canyons. It also bumps up the internal storage from 8 GB to 32 GB and tacked on even more battery life.

When put to the test, we verified that the Apex 2 Pro simply goes and goes. At a stated (and confirmed) 75 hours of battery life in the GPS-only mode, this watch can’t be touched by watches of the same size when it comes to longevity. Other watches, like the Garmin fenix 8, can eke out more time by utilizing the sun, but command much more wrist real estate.

And while Garmin has consistently led the pack in terms of efficient app integration, we can now say that COROS has caught up. The COROS app is an enjoyable interface to use, and does an excellent job of displaying our recorded activities, tracks, and daily stats such as active energy, heart rate, and sleep metrics.

So, how could the Apex 2 Pro be better? For one: we did miss the helpful fitness stats, reports, and workouts from the Garmin ecosystem. Garmin has made a big push toward synthesizing all of the data their fitness watches soak up, and we do wish that COROS will make the same pivot. Beyond that, in the age of mega-bright AMOLED screens, the colors of the Apex 2 Pro were a bit muted compared to watches of a similar caliber.

Ideal for the adventurer or fitness devotee who wants it all without carrying a calculator on their wrist, the Apex 2 Pro lands as just about the perfect balance in our books.

In an update to the brand’s uber-popular running watches, the Garmin Forerunner 570 ($550) adds a brighter AMOLED screen, speaker and microphone combo, and additional triathlon training that make this one of the best running watches out there.

Building on the Forerunner 265 (a watch that we’ve previously hailed as the running watch), the 570 got more than a name change, and is now a better daily driver for runners. Comparing the 265 to the 570 side by side, the new screen is noticeably brighter (as well as slightly larger across the two offered sizes), but still minimal enough as to not weigh us down on runs.

The new speaker on the 570 is loud and will prompt you with things like lap reminders, while the microphone allows you to use Voice Commands, and ask the watch to set things like timers or begin activities. In a surprising (but appreciated) function, the 570 will have you to turn the watch upside down after a water activity and pulse sound to clear the speaker — smart. 

New multi-sport modes have been added to the watch to make it a better triathlon watch, narrowing the gap between the 570 and the top-tier 970. Building workouts with multiple components is now possible, and we had good success with constructing multi-sport days that combined swimming with cycling and running.

Due to the brighter screen, battery life on the 570 does take a hit compared to the older 265 (a tested 9 days with a daily run, compared to the 11 days we could get with the previous model). This is certainly a watch for those who run and train for fitness (and are home every night to plug in), instead of endurance athletes. For those folks, bumping up to the Forerunner 970 or Enduro 3 makes much more sense. Those watches also add on ECG support and better mapping abilities (the 570 supports basic breadcrumb navigation).

To be sure, we still think that the Forerunner 265 is an excellent watch — and as long as it’s available, we recommend snagging it if the upgrades to the 570 don’t woo you. The price jump from the 265 to the 570 was a large one, and the added $100 might be tough to swallow for the relatively minimal feature additions. That said, if the latest and greatest in running watches is what you’re after, the Forerunner 570 is it.

Read Review: Apple Watch Ultra Review: Silicon Valley’s Best Smartwatch Dropped, Drowned, and Frozen

Apple is the bestselling smartwatch worldwide, and it’s clear why — it’s undeniably the best smartwatch (not GPS watch; we’ll get to that later) on the market. Everyone we spoke with who had one gave glowing reviews. “After literally decades of not trying a smartwatch, I recently bought an Apple Watch. I love it,” said one initial skeptic.

Now tuned for the outdoors and fitness market, the new Apple Watch Ultra ($799) is upgraded to take on the rough and tumble in your day-to-day, and boasts a larger 49 mm titanium case, brighter 2,000 nits screen, increased water resistance (up to 100 m), and an extended 36-hour battery life. You’re obviously going to pay for all those upgrades, but we’re convinced that it’s well worth it.

As with all the watches tested, the Apple Watch Ultra can track sleep, steps, and calories and puts it in an easy-to-understand format. Further sports integration offers up structured workouts in nearly everything from running to swimming to strength training and kickboxing.

These modes can be customized (choose your warm-up and recovery periods, etc.), and it logs most all of the metrics we’ve come to expect in a fitness watch, such as heart rate, pace, distance, elevation, and more. For runs after work or a weekend strength training session, the Ultra has everything we need.

Having coached many runners who wear an Apple Watch, our resident trainer can say two things with certainty: The GPS is not great, and the battery life just isn’t there to compete with flagship watches. But now that the Ultra version brings on board a multi-GNSS chipset with multi-band technology, the location reception is tack sharp and on par with the rest of the field high-end watches, such as the Garmin fenix 8 and COROS Apex 2 Pro.

The battery life issue, however, continues to be a ding, and with Apple’s large 49mm always-on AMOLED screen, it’s tough to squeeze much more out of it without compromising greatly on functionality. While the battery life of the Apple Watch Ultra is given as 35 hours in normal smartwatch mode, that number goes down to about 12 hours in GPS tracking mode.

Still, if daily convenience and smartwatch features take precedence over a detailed fitness activity, the Apple Watch Ultra is for you. One big caveat — it only works with iPhones. If you don’t have an iPhone, we suggest the Garmin Venu 2 or Samsung Galaxy Watch 5. Both are similarly focused on fitness tracking while offering a wide array of apps and smartwatch features. But for the MacBook crowd, the Apple Watch Ultra is an easy go-to.

Adorning the wrists of workout enthusiasts everywhere, the Fitbit Charge 6 ($150) takes the crown for the best fitness tracker. The sixth iteration is less expensive than the fifth when it was introduced and features a few useful upgrades. 

The Charge 6 reintroduces the haptic side button to the Charge line of trackers, which brings you back to the main screen when pressed. It also has a slightly curved AMOLED touchscreen, and the battery life lasts up to 7 days — the perfect tracker to wear all week.

An optical heart-rate monitor for 24/7 monitoring is standard and provides accurate calorie-burn calculations, sleep and stress data, and heart-rate zones for working out. It tracks daily steps, calories burned, and active minutes to help you make informed health decisions based on hard data.

The Charge 6 has 40+ different sports modes for tracking, including running, walking, biking, swimming, HIIT, yoga, skiing, surfing, indoor climbing, and golf. If you’re looking for finer details such as cadence, power, or rep-counting for weight training, you’re out of luck — one of our most notable issues with the Fitbit. A built-in GPS tracker allows you to go without your smartphone during an outdoor workout.

The Charge 6 also now connects with third-party platforms such as Peloton, NordicTrack, and Tonal to integrate heart rate data with your workouts. 

A few bonus features not usually seen on trackers are the ability to get notifications (call, text, email, and calendar), control YouTube Music (since Fitbit was purchased by Google, Spotify is no longer controllable on Fitbit devices) use Google Maps and Google Pay. If you don’t need these features and you’re OK carrying your phone during activities that require GPS (such as walking, running, and cycling), we suggest the cheaper Fitbit Luxe.

Our resident fitness trainer and ‘bio-hacker’ put the Whoop Band ($239) to the test for an entire year before rendering our verdict, and we’re sold. This low-key wearable isn’t quite all the watch that the rest of our suggestions are, but it also has a different purpose: recovery. Aimed at monitoring a few simple metrics and comparing them against your ‘stress’ level, the Whoop Band is a tool developed that athletes can use in training programs.

Unlike most fitness watches, which mainly track activities and workouts, the Whoop Band tracks health metrics that lend insight into your overall recovery state. These include sleep — Slow Wave Sleep (SWS), Rapid-Eye Movement Sleep (REM), light sleep, and time awake are all measured — as well as skin temperature, respiratory rate, blood oxygen saturation, resting heart rate, and heart rate variability (HRV).

Whoop also tracks daily activities (through smart tracking or customizable entries) and caffeine or alcohol intake. All of this is synthesized on the Whoop app and provided as raw data and a ‘Recovery Score,’ which can be used to know when to lean into your workout plan and dial it back.

The Whoop Band is a simple device with a dense optical sensor on the back of the device for siphoning up your biometric data. Otherwise, there is no screen and a simple textile band that stretches with you. After one year of use, our trainer found the Whoop to provide fascinating insights into his daily and weekly training efforts, and while the novelty faded after about 3 months, he still found utility for the whole year.

We did find that the device does underestimate the stress effect related to strength-related activities, such as climbing or weight lifting, which didn’t put as much of a ding in the recovery metric as we thought it should. The recovery status can be tweaked by adding data yourself after the workout, but we found it to be a bit annoying to have to adjust the data.

If you’re a high-level athlete locked into an intensive training program, the Whoop Band may be an excellent tool for measuring recovery. It’s a minimal device for those uninterested in full-on fitness watches who still want the data to inform fitness planning. You’ll need to pay for the subscription (ranging from $199 to $359 a year), but if you’re invested in your health, that might only be a blip on the radar.

320 is a lot of hours. That’s how long Garmin specs its Enduro 3 ($900) watch to run with GPS running — and the sun shining. This big-battery watch is made to go the distance, and if you’re after the longest running fitness watch out there, we think this is the one to snag.

We took this watch to Patagonia to test those claims, and while the sun was often in short supply, the watch did last the entire 2-week trip off the cord, and tracked more than a few multiday treks in between. The UI is the same version used in our top pick watch, and Garmin delivers in the personal tracking metrics as always.

In fact, the only real UI differences between this watch and the fenix 8 are the lack of a microphone/speaker and no dive functionality. Otherwise, it’s the same watch (just in a different case).

On a day that the sun was shining, we got the watch to charge at a rate of around 1% per 15 minutes — if you set the watch in a prime position. This seems to be the hack needed to really leverage your solar watch, and considering the watch only uses 1% per day when run in the battery saver mode, it’s easy to understand how this watch could run indefinitely, given perfect conditions.

The Enduro is more than a big battery, too: it has Garmin’s latest six-LED optical heart rate monitor, tracks almost 100 activity profiles, and puts it all behind a Power Sapphire glass and titanium bezel. We tracked an entire four-day trek along the Patagonian Icefield, and the watch easily led us over remote passes and through glacial labyrinths.

Satellite reception is top-notch and dialed in with both Multi-Band tech, which improves reception in deep recesses like canyons or cities, and Garmin’s SatIQ, a smart functionality that toggles between satellite modes to keep battery usage as low as possible. On-device mapping is the leading edge of the current generation and almost lag-free when scrolling quickly.

That battery does take up some wrist real estate, and the watch itself is a little over 1.5” thick, though we found it easy to get used to. The $900 price tag is also on the high end, though not as high as you’ll pay for the current generation Fenix 8. The Enduro 3 is instead for folks who simply need a watch to last and can sacrifice the latest and greatest features to get it.

While we’ve now pivoted our best budget suggestion to the new COROS Pace 4, there’s still a compelling reason to consider the $200 COROS Pace 3 while it’s still available. For one, it’s now $20 cheaper than it was previously, making this watch an even better value for the buck.

While the newer version added a super-bright AMOLED screen, it does soak up a good bit of juice to run full-time. For those who prefer the more neutral lighting of a Memory in Pixel screen, the older Pace 3 has got you covered. Even with all satellite systems running at high fidelity, the newer Pace 4 does run for longer (a claimed 30 hours) compared to the Pace 3’s 25 hours, so it’s a testament to COROS’ battery management to accomplish this, despite the pivot to a more battery-draining screen.

Both watches use the same set of five GNSS systems (GPS, GLONASS, Galileo, Beidou, QZSS), and both benefit from Dual-Frequency reception, which aids in getting a signal in dense cover such as canyons or cities. Like the 4, the 3 can be navigated with simple breadcrumb maps, which will be enough for some folks. If not, you can bump up to the Pace Pro ($349).

So what’s been left off? For one, the lesser glass in the screen, which is scratch-resistant (read: not scratch-proof), and the polymer bezel, which won’t be indestructible. While easy to use, the mapping functionality is a bit limited and lacks the detail of many mid-tier watches. Finally, it’s tough to match the workout planning metrics that the Garmin ecosystem brings to the table, but COROS has made big improvements as of late.

Sliding in at an impressive $200 ($49 less than the newest version), the Pace 3 is nigh impossible to deny for the price. This watch boasts many of the same features as watches that demand hundreds more, and is likely still one of the better options available currently for anyone looking to dip their toe into the fitness watch market.

Read Review: Sunny Suunto: ‘Vertical’ Sports Watch Gets Solar Charging, Offline Maps

Suunto has jettisoned itself squarely among the leaders in the GPS watch world with the new Vertical ($499), a watch that hits almost all the marks when it comes to a feature-packed wearable with plenty of horsepower under the hood.

The Vertical salves all of the things that didn’t quite make the grade for us with the Suunto 9 Peak Pro (still an excellent watch, read below), including brightening up the screen, adding Wi-Fi, and incorporating dual-band GNSS reception, and cements itself as a true flagship watch — landing among the Garmin fenix 8, and COROS Vertix 2.

Then there’s the new mapping functionality, something that Suunto hasn’t incorporated into a device since their Suunto 7 watch. The company has taken the time to perfect it as well because, in the Vertical, it’s an excellent rendition.

From the Suunto app, users are able to download (for free) shaded topographic maps for essentially the entire globe — directly onto the watch. These maps are sufficiently detailed for phone-free navigation, and can have routes uploaded to them from the app for course-making on the go.

And if all that wasn’t enough, Suunto also was able to boost its battery numbers by a substantial amount over the 9 Peak Pro, stretching the life in ‘Performance’ (all systems go) mode to an impressive 60 hours. We tested the Titanium Solar version of the watch, which leverages a solar watch face to juice up the Vertical on the go. This added feature will cost you (to the tune of $210), but it greatly extends your untethered time.

While the Vertical does not have any music-storing abilities on the device (a functionality the Garmin fenix 8 boasts), it can control the music playing from your phone. This is a small ding in an otherwise iron-clad GPS watch, and the Vertical would be an excellent timepiece for anyone who lives on the cutting edge.

The Garmin Instinct 3 AMOLED ($500) is an update on a previous favorite of our team, and it’s only better now. Newly optioned in a beautiful AMOLED screen, the Instinct 3 is still just as get-er-done as the previous version — it just looks even better now.

The Instinct line keeps things accessible by holding back on a few metrics but leaning into the rugged durability and styling that appeal to many. Notably, the satellite reception is limited to three systems, and the battery life isn’t as dazzling as the upper-tier watches, but there’s considerable tech trickle-down from other Garmin watches that make this updated version a worthy one.

The big deal here is the AMOLED display, which is just as brilliant as the ones we’ve used on the Forerunner series. The touch sensitivity also appears to be better on this version of the watch, and the screen scrolls beautifully. There’s still a solar-charging MIP version ($400) of the Instinct 3 for loyalists, but we’ve been enjoying the deeper colors and better contrast.

On-watch mapping won’t blow you away (you get the standard breadcrumb-tracking style screens), but the watch does use Garmin’s SatIQ technology, which decides which GPS mode is ideal for the terrain you find yourself in. This means that the watch will toggle into Multiband mode when you’re in a city or tight canyons, which is a boon for battery life.

The new Instinct is also tougher, with a new metal band set into the bezel as reinforcement. The watch still meets MIL-STD-810 mil-spec standards and is rated to 10 atmospheres of water immersion. We found that the fiber-reinforced polymer bezel tended to glance off things we hit instead of scratching, and while the screen is only chemically strengthened glass, the raised bezel protects it well.

There’s impressive value in Instinct 3, too. For the same price as the COROS Apex 2 Pro, you get an AMOLED screen that pops in all conditions, whereas the COROS could, at times, be a little harder to see. That said, the battery life on the COROS when running single-band GPS is 75 hours, and while the 32 hours the Garmin can manage is decent, it’s the reason we think the Apex 2 Pro is a slightly better mid-tier watch.

If your workouts keep you closer to home (and you tend to get dirty doing them), we don’t see any reason not to stick with the rugged Instinct 3 AMOLED.

While your Garmin, COROS, and Suunto options dominate the fitness watch space, there’s always room for some friendly competition, and the Amazfit Cheetah Pro ($300) angles directly at the big dogs with a suite of features more often seen in watches hundreds of dollars its senior. 

With dual-band multi-GNSS reception, a 1.45” AMOLED screen, and navigation capabilities, the Cheetah Pro checks all of the boxes we’re looking for in a fitness watch that we can use for everything from days in the gym to long events outdoors. The watch also tracks 156 (!) different activities, and shuttles that info over to its app for post-workout breakdowns and training suggestions.

In practice, our testers found that while the feature set of the Cheetah Pro is exhaustive, the polish and execution left a little to be desired. For example, when tester Ian Atkinson ran a 24-mile route in the Canyonlands Needles District recently while comparing the Amazfit to the proven COROS Pace 3, the Cheetah lost satellite connection a number of times, while the COROS held strong.

While it’s no death knell, connection quality is certainly something we look for, and with watches getting just so good these days, we’re eager to see some improvement from Amazfit in this space. Further, while the Zepp app — used to provide training insights and plans — is a detailed offering, the AI training provided is a bit lacking, and advanced functionality is limited to paid subscriptions.

So, can the Cheetah Pro hack it? “I would say yes,” says Atkinson. “I was not gentle in my testing, and the Cheetah Pro withstood both ample amounts of sand and gritty rock. It just depends on what your standards are for a fitness watch.” For hundreds less than the competition, there’s much to enjoy on the Cheetah Pro, and if you’re willing to forgive some rough edges, it’ll track everything you get up to.

The Polar Vantage V3 ($700) is once again one of our preferred picks for running, even in a field dominated by Garmin. It’s not as jam-packed with features as most Garmins, but what it does offer, it does very well — especially heart-rate monitoring.

The biggest new feature since the last model is the addition of offline topographic maps, bringing this watch closer in features to a Garmin adventure-focused watch. It also has over 150 customizable sports profiles.

In addition, the battery life has been extended to 61 hours in continuous GPS mode with the option of 140 hours in battery-saver mode. The screen has been updated to an AMOLED display. Sensors for SpO2, ECG, OHR, and skin temperature have been added to the Vantage V3. 

Like all watches, you get training and recovery insights based on your unique physiological data to help you make more informed decisions about when to push and recover. It comes with built-in, step-by-step running and cycling performance tests to establish training zones via heart rate, speed, and power (meter required for cycling), as well as test recovery.

If you’re a Strava Segment-hunter, the watch will notify you as you approach your starred Segments and give real-time performance data so you can crush your Segment PRs.

Polar Precision Prime sensor fusion technology “combines optical heart-rate measurement with other sensor technologies to rule out involuntary movement that might disturb the heart-rate signal and produce unreliable readings.”

We weren’t, however, as impressed with the Polar Flow app that is used to sync your activities online — which is a bit simple and often has issues syncing data between the watch and your phone. Additionally, the buttons and interface were not as intuitive as other watches we tested. But these issues aside, the Vantage V3 is rightly up there with the Garmin Forerunners for our suggestion of the best running watches.

The Garmin vívoactive 5 ($300) combines basic fitness, health tracking, and performance statistics with classic smartwatch features like music, smart notifications, and texting.

For the everyday athlete who doesn’t need all the features or the price point of a watch like the fenix 8, but wants data more than your average fitness tracker or smartwatch, the vívoactive 5 is a good option. If you’re looking for more outdoor-specific features like navigation and more in-depth training features, a higher-end watch would be a better pick. 

Some of the updates from the previous version include nap tracking, a new Morning Report, and an AMOLED screen compared to the MIP screen on the vívoactive 4. It also includes a new wheelchair mode, which tracks pushes and workouts. The vívoactive 5 also starts at a lower price point ($300) than the vívoactive 4 ($350). 

With features like sleep scores and tracking, energy monitoring, and basic training statistics, the vívoactive 5 keeps you aware of any changes in your health or activity levels. The vívoactive 5 has up to 11 days of battery life in smartwatch mode and up to 5 days, with the AMOLED touchscreen in always-on mode. For those looking for a smartwatch with a little extra under the hood, the vívoactive 5 is an excellent option.

Hot on the heels of the already-impressive Vertical, the Suunto Race ($399) slides in hundreds less and better suited for the runners out there — all while boasting Suunto’s first AMOLED screen. This beautiful display is a showstopper and it’s not difficult to call this the best watch Suunto has ever made.

Like the split between MIP and AMOLED screens on otherwise similar watches, the Vertical and Race also share a lot of like features, but there’s also a good bit new on the Race. For example, the new digital crown bezel makes navigating through maps a breeze and moves away from the three-button layout for the Vertical.

HRV tracking has also been expanded to nightly surveying, and integrates with the newly added Suunto Coach functionality — synthesizing your workouts and providing feedback and suggestions.

The AMOLED screen can’t be ignored, however, and is a 466 x 466-pixel resolution unit that blows MIP screens out of the water when the light starts to wane. We especially noted this during map navigation, which is sharp when viewing turn-by-turn directions or zooming in or out of maps.

The processor on the Race is also top-notch, with none of the lagging that we’ve unfortunately dealt with on previous Suunto watches. Map and compass rotations are smooth, menu switching is clean, and post-workout screens flip through easily.

Like the Vertical, the Race has onboard map storage in either 16 GB or 32 GB capacities, depending on the variation you choose. These are non-routable maps, meaning your turn-by-turn route won’t update should you miss a fork in the trail, but the definition is still top-notch. The Suunto app allows for quick shuttling of maps over to the watch over Wi-Fi, and uses a smart map area picker that only downloads the sections you’ll need.

Stacked up next to the Garmin Forerunner 570 and Polar Vantage V3, the Race makes a compelling case for itself, with a much longer comparative battery life than the 265, and a more user-friendly button interface and app than the Vantage.

That beautiful screen will ding the battery life on the Race compared to the Vertical, however, with a 20-hour difference between both in the Endurance mode. Still, a full 40 hours in the highest-demand GPS mode is nothing to shake a stick at, and most runners will find this more than enough for weekend ultras.

For those engaged in endurance events, the Vertical’s longer battery life and available solar watch face may prove more tempting, but for casual and spirited runners alike, the Suunto Race has everything we’ve been wanting from a Suunto watch and more. It’s easy to say that this watch is well competitive with top-tier Garmin and COROS options, and we’re excited to see it.

How We Tested the Best Fitness Watches

Comparing fitness watches can be a fairly complicated task, as there is a blizzard of different sensors and metrics to compare. To truly gain a good understanding of each watch, it takes a solid week or more to accumulate the logged data. Thankfully, this is what we’re here for, and our in-house experts have the know-how to compare everything from the differences in optical heart rate monitors to dual-band satellite reception and tracking.

  1. Field testing: When we truly hit the field, our testers aim to get each of these watches out for at least three different types of activity tracking modes — running, cycling, and swimming are our most commonly used.
  2. Health data tracking and measurement: After this, we compare track lengths, measure heart rate data against dedicated chest-strap devices, challenge the satellite reception with difficult terrain, and run each of these watches completely dead — all in the name of winnowing out the chafe and finding the best fitness watches available today.
  3. Battery charging and waterproofing tests: Recharging times from a completely discharged state are timed, as are discharge rates with watches in their lowest power consumption modes. Water resistance is also challenged with the help of our garden hose.
  4. Our fitness watch rating system:
    • Activity Tracking & Accuracy: The variety, accuracy, and types of data collected during your activities is the whole point of a fitness watch, and we rank it highly whenever we run a unit through the paces. Besides looking at overall activity types and the information collected, we compare the watches against known standards such as running on a track or counting reps.
    • Battery Life: We specifically examine battery life when using GPS tracking to compare run times and aim for at least a solid day’s worth of battery power to earn a high score in this metric. Anything more than this puts the watch in the endurance category, and anything less means it’s likely a smartwatch with fitness features.
    • Training Data & Planning: Most fitness watches utilize data from your fitness activities to create personalized training plans, but the style and complexity of these plans can vary significantly. We look for advanced metrics that take into account your overall health, such as sleep tracking, as well as associated apps that allow you to input additional data, like food intake or adjust tracked activities.
    • Build Quality: Ultimately, we assess the overall build quality of these watches when rating them. Bezels and watch faces can vary in construction, with those sporting sapphire glass and titanium earning higher scores. We also look for high-quality optical heart rate monitors, straps, and charging solutions.

Our Testing Process and Testing Grounds

Our experts have crafted a detailed testing regimen that aims to compare these watches on a level playing field. It’s not uncommon for our testers to wear three or more watches at once to give them a fair shake.

From the start, we aim to use these watches in two broad field testing categories: gym work and outdoor activities. Our time in the gym provides us with deep insights into the nitty-gritty comparisons between watches when it comes to heart rate tracking and training suggestions, as well as the finer details, such as which watches count our reps the most accurately and which have the best sense of when we need to recover.

Our Expert Testers

GearJunkie knows fitness, and our testers know their watches. The team includes Cory Smith, an online running coach and freelance journalist with over 25 years of running and rock climbing experience. He’s an expert, from treadmills to shoes

Our most recent fitness watch update saw contributor Ilana Newman saddled with more watches than she has wrists to put them on, putting them through the paces in southwest Colorado while trail running, backcountry skiing, and working through daily fitness regimens. The San Juan mountains provided the perfect testing ground for this new generation of watches, and Newman is obsessed with training data and staying up to date on the newest outdoor gear.

Beyond their personal expertise, GearJunkie has solicited the opinions of fellow runners, hikers, and climbers. When the dust settled and the final grades came in, the list above represented the best fitness watches we could drum up. But know that fitness tech is constantly improving, and new functionalities are being added daily to some of these watches. As they improve, so does our coverage, and we’ll continue to test them.

Buyer’s Guide: How to Choose the Perfect Fitness Watch

The fitness watch market can be overwhelming. There are so many options — all of which might seem similar — that it can feel as though you need a college degree to tell them apart. 

While finding the best fitness watch for you does require some thought and research, this handy how-to-choose guide has all the essential information compiled so you can make the best decision for your fitness watch needs. 

We go into everything from GPS reception to how training data is used to provide health and performance predictions. Each brand of watch uses slightly different data and provides different features, each of which is more or less important to consumers. We’ll spell it all out for you so you can make an informed decision that works for your specific fitness, health, and performance goals.

Smartwatches, GPS Watches, and Fitness Trackers

There are three very distinct categories of watches, each with strengths and weaknesses. Smartwatches are basically small smartphones for your wrist where you can add apps and take calls without your phone.

The most popular smartwatches are Apple and Samsung Galaxy watches. Functionally, they’re geared toward convenience and health tracking, but they tend to fall short on battery life, GPS accuracy, and workout functionality.

GPS watches such as Garmin, COROS, Suunto, and Polar are designed primarily for workouts that require GPS functionality (running, cycling, hiking, swimming, etc.). They tend to have over triple the battery life of smartwatches and are very strong with workout features, metrics, and tracking.

While most will allow text and email messages, and many provide storage for music or access to streaming apps like Spotify, they’re limited in the scope of apps you can add and will not replace your smartphone.

Fitness trackers have the least functionality and only track health and fitness metrics such as resting and variable heart rate, sleep patterns, and steps. Most will need to stay connected to a phone for features like GPS tracking.

Activity Tracking

A good fitness watch will have specific activity profiles and associated information to display; (photo/Matthew Tangeman)

Today’s fitness watches can track just about any activity imaginable, ranging from running to indoor rock climbing and even surfing. We’ve found that watches labeled as “outdoor” or “multisport” not only tend to be able to track the more obscure activities but also do so with more detail and granularity. As a result, this increased level of functionality tends to come with a higher price tag.

Some more entry-level watches do allow you to create new activity profiles for sports that are not built-in, but most of the time these only allow you to track the basics like heart rate, time, etc. 

For example, while you could track rock climbing with the Garmin vívoactive 5, it does not have a specific profile for it, so you would only get basic data logged for that workout by using a different activity profile, such as cardio. The Garmin fenix 8, however, has specific rock climbing (indoor climbing, climbing, and bouldering) activity profiles that allow you to track each route, the grade of the route, and the length of each climb. 

Backcountry skiing is another specific activity that testers found lacking on some of the lower-end watches, as a session includes both uphill and downhill travel, logging it without a backcountry skiing-specific activity profile creates an inaccurate representation. Even using cross-country skiing as a substitute on the Fitbit Charge 6 did not provide the same overall picture as using a backcountry skiing profile on a watch like the Polar Vantage V3.

Depending on the brand and the activity being tracked, you will be able to see different data both during the activity and in the activity summary after completion. If the watch supports navigation, and you’re tracking an activity that involves moving, one screen will feature a map with your location. 

High-end Garmin watches like the fenix 8 series feature over 80 activity profiles with the ability to add more. The Polar Vantage V3 can hold up to 14 profiles on the watch and requires the Polar Flow app to edit or add more. COROS watches have about 30 activity profiles, but veer more toward technical outdoor activities instead of gym activities like Fitbit fitness trackers do. 

All the watches we tested tracked common activities such as walking, running (outdoor, trail, treadmill), outdoor and indoor cycling, yoga, elliptical, general strength, and cardio sessions. If there’s a less-common sport you’d like to track, we suggest checking the watch’s spec sheet to see if it’s covered.

Training and Coaching

As fitness watches have gotten better at tracking health and fitness data, companies have been able to use that data to give guidance on training. As a full-time running coach, our tester Cory Smith finds this particularly interesting.

He sees most runners struggle because they overtrain or undertrain. Garmin and Polar seem to have the best training and coaching insights, with COROS right behind them.

Garmin, as the leader in the field for training data and even coaching through the watch interface, has a few statistics that seem to be included across its newest watches, no matter how high-end it is. Even these baseline stats can provide a good overview of training readiness and recovery. 

Recovery time, for example, is included on both the vívoactive 5 and the fenix 8. Garmin’s recovery time uses data from your past workouts, including your recent and long-term training load and VO2 max. Other data, like sleep and stress tracking, can also impact recovery time.

Another now-standard piece of training data for Garmin is Heart Rate Variability Status (HRV), which tracks the time in between heartbeats to determine the level of stress your body is currently under, due to training load, life, lack of sleep, and more.

Garmin also uses all of the data it constantly gathers during the day and activity tracking to provide workout suggestions. High-end watches, like the fenix 8 or Enduro 3, provide a specific workout each day in the Morning Report, with specific goals like “base building” based on past activities and current training status.

There’s also the option to set up Garmin Coach on any Garmin Watch, which uses the Garmin Connect app to choose a training goal — such as training for a half marathon — and Garmin Coach will provide a training plan over an allotted time. 

Polar uses similar data to provide data like Cardio Load Status, which looks at short-term training load (strain) versus long-term training load (tolerance) to determine the effect of your training (detraining, maintaining, productive, or overreaching).

Health Tracking

More in the realm of smartwatches and fitness trackers, even GPS watches offer insightful health tracking info; (photo/Matthew Tangeman)

Health tracking is standard across fitness watches, from the most basic fitness tracker to the highest-end GPS watch.

Technology for health tracking has advanced a lot over the past few years, and certain features that used to be considered high-end are now available on just about every fitness watch, like SpO2 (blood oxygen saturation — measured through red and infrared light) and Heart Rate Variability. 

Every fitness watch measures heart rate and sleep, while some, like the Whoop Band 4.0, focus intensely on it. Additional health data, such as calories and hydration, are available on most watches we tested, but must be tracked manually. 

The Apple Watch provides heart health alerts for low or high heart rates and also allows for medication reminders. All fitness watches provide menstrual cycle tracking, and many have integrated mindfulness into their interfaces, like the Garmin vívoactive 5. 

Garmin watches now also track naps, along with overnight sleep. Each brand has its own way of summarizing a night of sleep, but most use a scale of 1-100 to rate the night of sleep while also tracking time asleep and sleep cycles. 

Health tracking features are generally standard across brands, but each brand has features that synthesize data in unique ways, like Garmin’s Body Battery and Fitbit’s Daily Readiness. 

Garmin’s Body Battery, for example, uses data from sleep, stress, rest, and physical activity to provide a score from 1 to 100 for physical energy. Your Body Battery will be highest upon waking and ebbs throughout the day, depending on activity and stress (measured through heart rate variability).

Some Garmin watches additionally provide insights such as “Easy Day: Your day has been easy so fa,r and you have plenty of energy left for exercise or activity.” Other brands have similar features with different interfaces.

Navigation and Mapping

On-device navigation has come a long way, and is now very impressive on flagship watches such as the Garmin fenix 8; (photo/Matthew Tangeman)

If navigation and mapping are important to you, you’ll have to shell out some cash. You can get some basic navigation features like waypoint markers and tracking integrated into your phone without needing to go for top-of-the-line watches. But if you’re going to be using your watch off-grid and want to upload your own .gpx tracks, you’ll need to go for a higher-end Garmin, COROS, or Polar watch. 

Entry-level Garmin watches like the vívoactive 5 that include GPS but lack navigation often feature a back-to-start mode that allows you to use an on-screen compass to return to where you started recording without an on-screen map. 

Watches with full GPS navigational capability and onscreen maps, like the fenix 8, Polar Vantage 3, or COROS Apex 2 Pro all allow you to download maps and .gpx tracks for navigation. They all come with basic maps installed, and the ability to add maps is available through each brand’s app or website.

Garmin’s high-end watches like the fenix 8 have a navigational feature called ClimbPro that shows the remaining distance for a section of uphill travel. Garmin watches also include pre-downloaded ski resort maps for 2000 ski resorts worldwide.

Garmin, as well as COROS, includes off-track alerts as well as turn-by-turn directions to a predetermined location.

Smartwatch Features

If you want the most smartwatch features, an Apple Watch or similar will be the way to go. But most fitness trackers and GPS watches also include an assortment of smartwatch features. 

After Apple and Fitbit, Garmin has the best smartwatch features. Other brands, like Polar and COROS, forgo features like contactless payment for better heart rate tracking and outdoor-focused features. 

Pretty much all fitness watches sync with your phone and provide notifications for texts and other alerts — if you want. You can also turn this off if you’re in the camp that seeks fewer distractions. 

Many Garmin and COROS watches also feature offline music storage, while lower-end watches have compatibility with music streaming apps like Spotify and have music controls. All Garmin watches now feature Garmin Pay and have the ability to download many third-party apps for various additional features through the Garmin ConnectIQ store. Some watches, like the vívoactive 5, even allow you to respond to Android phone texts through the watch’s onscreen keyboard.

Accuracy and Sensors

Global Navigation Satellite Systems

Most GPS devices are accurate within 1-3%. In our testing, all GPS-focused brands (Garmin, COROS, Polar, and Suunto) performed equally in GPS connection and accuracy. Connection time varied from 10 seconds to a couple of minutes, while distance was within the 1-3% margin.

It’s important to remember that location has a lot to do with GPS connection and accuracy. Accuracy depends on multiple satellites communicating with each other freely and reporting back to the watch.

Distractions such as buildings, trees, cliffs, and clouds can affect the satellites’ ability to pinpoint the watch sensor. We suggest asking fellow athletes in the area where you’ll be working out to find out how their watch’s GPS performs.

GPS isn’t the only game in town when it comes to satellite navigation systems, and many new fitness watches are integrating other global systems to increase fidelity in their location technologies.

GLONASS is a Russian satellite navigation system that provides global positioning data in the same way that the GPS system does, and can provide more definition in high latitudes. Galileo is operated by the European Union and also offers full global coverage.

The BeiDou Satellite Navigation System is operated by China, and while originally only providing coverage to eastern Asia, it went global in 2020. And finally, QZSS, a Japanese system, provides coverage over the Asia-Oceania regions.

Because different satellite systems have undergone multiple generations of satellites, each operates on a different frequency than the last. These older satellites are still functional and provide more data that leads to a much higher fidelity signal when combined with one another. This is multi-band GNSS (Global Navigation Satellite System) technology, and more and more fitness watches today are incorporating it into their builds.

Barometric Altimeter and Compass

Most outdoor-focused fitness watches now come with barometric altimeters and compasses that support their navigational capabilities. This is where the older term ‘ABC’ watch comes from.

Barometric altimeters measure elevation through air pressure. They can also predict incoming storms and weather patterns.

Polar and Garmin both have options to set their watches to one of three settings: Automatic, Barometer, and Altimeter. ‘Barometer’ locks the watch in a mode where all changes in pressure will be considered due to weather and changes in ambient pressure, while ‘Altimeter’ considers all changes in pressure to be due to elevation change. Automatic determines the best mode for your current activity. 

Pretty much all fitness watches that include GPS, even without full navigational capabilities, include a compass. This allows for back-to-start navigation and basic orientation without service.

Heart Rate Monitors and Pulse Oximeters

Monitoring heart rate is one of the most basic features of any fitness watch or tracker, and pulse oximeters have become standard over the past few years. These two sensors allow users to monitor training strain and overall health. 

Each brand of watch uses a slightly different technology to analyze and interpret heart rate data, but they all use similar ways of measuring optical heart rate, known as photoplethysmography (PPG). A green light shines from the back of the watch, through your skin, and reflects off of red blood cells in your veins, measuring blood flow. 

Pulse oximeters measure blood oxygen content, which is most useful at high elevations to determine adjustment to altitude and performance ability. Fitness watches use red and infrared light to estimate the percentage of oxygen in your blood. While useful, especially for altitude training, watch pulse oximeters are not as reliable as fingertip pulse oximeters.

Battery Life

This is the most notable difference between smartwatches and GPS watches. On average, smartwatches need to be recharged every 24 to 48 hours, whereas GPS watches can last 5 to 20 days between charges.

These times are ever-increasing, thanks to the integration of solar charging on some of the more premium models. Solar charging, like with the Garmin fenix 8 or Enduro 3 uses a Power Sapphire lens to convert sunlight into power, extending the charge of your watch, depending on sun exposure.

Many factors influence how long your watch’s battery will last, including what you’re using it for. If you’re using GPS tracking (and single GPS versus multi-GNSS mode matters), your battery will die faster. Most watches advertise battery life with and without GPS. 

For example, the COROS Apex 2 Pro advertises 75 hours in GPS mode (GPS + QZSS) and 45 hours with five satellite systems (GPS, GLONASS, Galileo, Beidou, QZSS), and 30 days for daily use without GPS tracking. 

Charging time is relatively quick, with most offering a full charge in around 2 hours. If you’re like us and hate having to constantly charge yet another device, we recommend a GPS watch with a longer battery life.

Design

Size

Outdoor and multisport watches are often larger and heavier because of the sheer number of features (and extended battery life), so much so that they can look too big and awkward on small wrists. If you prefer a smaller size, most brands (including Garmin, COROS, and Polar) offer smaller versions of flagship models. 

Buttons and Dials

The physical design of watches varies across brands, with some using a two-, four-, or five-button layout, others using a dial and buttons, and others using no buttons at all. 

Garmin tends to have two-, four-, or five- buttons on its watches. Its lower-end watches tend to have fewer plastic buttons, and premium watches feature more metal buttons. Each button can be programmed as hotkeys (press and hold) to access various screens such as music controls, settings, timer, alarm, and more. In our testing, we found that the Garmin buttons feel intuitive, but the left-side buttons can be hard to reach.

Polar uses a similar layout of buttons to Garmin, but we found the material used for its buttons to feel less satisfying and reliable when in use. 

COROS and Apple use a combination of buttons and dials. The dial is useful for looking through lists at a glance, while buttons help make choices and find more in-depth information. 

Most watches have ways to lock the button use, which can be convenient when you don’t want your watch to change screens. Fitbit, however, has mostly eliminated buttons and uses haptic sensors on one side of the Fitbit Charge 6. Testing found this to be much less reliable compared to buttons on other watches, but it does provide a simple design.

Displays and Touchscreens

Nowadays, most fitness watches feature touch screens, although some are still button-only. The type of screen depends on the watch and the brand.

There are two types of displays found on fitness watches — AMOLED (Active Matrix Organic Light Emitting Diodes) and MIP (Memory in Pixel). AMOLED displays are brighter and perform better in low light, but are not always great under direct sunlight. These are your smartwatch screens that look more like a smartphone. They also use up battery quickly when always on, so they usually are ‘lift’ or ‘tap’ to wake. 

MIP screens look duller at first glance, with colors showing up differently than on your phone. They use reflective LCD technology that depends on ambient light for visibility. This allows them to be always on and show up brighter in bright sunlight. They use less power than an AMOLED display. 

Outdoor-focused watches typically feature an MIP screen since this is the battery-friendly option and allows for better visibility outside, while smartwatches tend to have AMOLED displays. Some watches are even offered in both styles, such as the Garmin fenix 8.

The actual material used for a screen also matters, especially if you’re going to be using it for high-impact activities, or just tend to beat up your belongings. Sapphire glass is one material used by Garmin, Apple, and other watch brands that is incredibly crack and scratch-resistant. Another common material for fitness watch screens is mineral glass, which is cheaper but scratches more easily.

Watch Bands

Most fitness watches come with silicone watch bands that are easy to swap out. Depending on the type of watch, alternative watch bands can be found through the manufacturer or, depending on the type of watch, through third-party sites. You can choose between various textile, rubber, or even leather watch bands.

Silicone is the best for active use, although some designs do need to be cleaned and dried often to avoid the build-up of sweat and grime. Textiles or leather can look nicer.

User Experience, Ecosystem, and Apps

Perhaps as important as the fitness watch itself is the depth and strength of its ecosystem. An ecosystem is composed of the watch’s application, web portal, and supported third-party apps such as Strava and Spotify. To view your data, you’ll need to download an app on your phone.

As Garmin is the largest fitness watch company, it has the broadest and strongest sport-specific ecosystem. Garmin’s app and web portal, called Garmin Connect, displays just about all the performance and health metrics you need. Polar’s Flow app and web portal follow close behind Garmin, with COROS and Suunto following Polar. Amazfit’s Zepp app is a bit of an outlier, though it shows function and promise.

Price & Value

Price can give you a good measuring stick of the features of a watch, and there’s a pretty wide range when it comes to fitness watches, especially among different styles. Fitness trackers tend to be the cheapest, with smartwatches asking a bit more and GPS watches commanding the most.

Budget

The universe of fitness watches is a big place, but that doesn’t mean you have to drop a grand to get some solid fitness tracking ability. This is the realm of fitness trackers and light-duty smartwatches, as well as some budget-minded GPS watches that trim some of the extra functionality to hit a more approachable price. Expect these devices to track everyday metrics such as heart rate, calorie burn estimates, sleep data, and a number of different activities.

Entry-level fitness watches tend to cost between $150 and $300 and will typically track in GPS mode for between 20 to 40 hours. The COROS Pace 3 ($229) is at the top of the heap and leverages an energy-sipping MIP screen to do it. The Garmin vívoactive 5 ($300) won’t track for as long, but the sharp AMOLED screen is far better for folks using the watch indoors as much as outdoors.

Mid-Tier

If you’re an active person interested in more detailed fitness metrics such as your VO2 max and activity intensities, a mid-tier watch is likely the way to go. These watches tend to cost between $400 and $600 and will open up a great deal of training ability, as they often incorporate adaptive training programs that synthesize your tracking data and use it to inform your progress.

Spending a bit more opens up more software power and greater hardware. Heart rate sensors will have multiple LEDs to obtain a more accurate reading, and satellite chips will tap into a greater number of global satellite networks and sometimes additional satellite bands as well.

The COROS Apex 2 Pro ($449) is our favorite mid-tier watch at the moment, as it piles on the functionality with a built-in barometer, altimeter and compass, on-watch navigation, and some mapping features.

Premium

If you’re an ultra-racer who needs extended battery life for into-the-night endeavors or a multi-sport athlete who needs extended specialized functionalities like depth alarms for diving or heart rate variability, then spending the dough to get a one-and-done watch can make a lot of sense. These watches often have larger bezels to accommodate bigger batteries, and with them, GPS-tracking times between 60 and 90 hours. Solar screens are also available, helping to keep your watch topped off.

The Garmin fenix 8 ($1,100) is near the top of the price range, but for good reason — it’s got nearly anything you could want. Flagship watches like this sport the most activities tracked (80+), receive dual-band GNSS data, and have user-programmable buttons and touchscreens. The Apple Watch Ultra ($799) is certainly premium when it comes to smartwatches, and the Garmin Enduro 3 ($899) boasts huge battery life numbers.

Frequently Asked Questions

How does a fitness tracker work?

A fitness tracker’s primary purpose is tracking health data such as heart rate, sleep, steps, and calories. It uses sensors in the band or watch to monitor. Most fitness trackers need to be connected to your smartphone to access the data.

Fitbit vs. Apple Watch Ultra — Which is better?

If you have an iPhone, we would recommend the Apple Watch Ultra. It’s the bestselling smartwatch, and everyone we spoke with absolutely loves it. If you don’t have an iPhone, the Apple Watch will not work.

Fitbit is a great choice, but with Google’s recent acquisition in limbo, the future of Fitbit as we know it today is in question.

What fitness watch is the most accurate?

This is a tough question to answer. It depends on what features you’re talking about. In general, we found Apple watches to have the best health tracking, Garmin to have the best GPS tracking, and Polar to have the most accurate heart-rate monitor.
