Best Fitness Trackers and Activity Monitors of 2017

Searching for a new fitness tracker to counteract all of the indulgences of the holiday season? After extensive research, we bought the top 19 fitness trackers and after over a year of side-by-side testing, we were ready to select our award winners. We walked thousands and thousands of steps, climbed flight after flight of stairs, and completed dozens of rigorous workouts to assess the performance of each tracker at monitoring your fitness. We also ranked and scored the ergonomics and aesthetics of each model, as well as how easy it is to use and how effective it is at aiding you in establishing healthy habits. Check out the full review below to see which trackers are the best at motivating you to get off your sofa, supplement your existing training scheme, and which one is the best bet when shopping on a budget.

As winter rapidly approaches, we have added three new products to our review to see if they were up to the challenge of getting us up and active instead of eating holiday pies and treats. Unfortunately, the Garmin Vivoactive 3, the Garmin Vivosport, and the Huawei Band 2 Pro failed to impress, with none of this trio performing well enough to win an award. For now, at least, our current award winners below are the best around, but you can look at the full comparison review below and the individual analysis of the three new products to see how they stacked up.

Earning one of the top scores overall, the Fitbit Blaze handily claimed an Editors' Choice award and the title of Best Overall Fitness Tracker. This semi-smartwatch delivered a superb performance in our Fitness Impact and Health Impact metrics and has a fantastic display. It is one of the most accurate trackers around when it comes to counting flights of stairs climbed and steps taken. It has a phenomenal display and a fantastic online ecosystem that makes it easy to compete with friends and family in fitness challenges or in non-competitive "Adventures" with yourself. In addition to being an exceptional fitness tracker, the sleek and stylish Blaze is packed with a decent amount of smart features and functions, receiving text, call, and other notifications from your phone right on your wrist. It is also compatible with a large assortment of different bands to match every occasion, whether you are going to the bar or the boardroom. However, we did find the Blaze to be a bit on the larger side and isn't necessarily the best choice for those that want a more petite tracker.

Only narrowly missing out on the top spot, the Surge by Fitbit only trailed the Blaze by a single point. This watch has a built-in GPS unit in the device itself, boosting its standalone capabilities exponentially and allowing you to leave your phone at home. However, while this is a great all-around fitness trackers, Fitbit does plan on discontinuing it in the future with the release of their first smartwatch, the Fitbit Ionic. However, this wouldn't dissuade us from recommending it, especially if you can find it on sale. The Surge can track an impressive array of stats, providing you with accurate distance, speed, and average speed during your workouts, as well as tracking your route for later review. This caused it to earn one of the top scores overall when we evaluated the fitness impact of each tracker. This tracker is a little on the bulkier side, but it is comfortable and is definitely a model to consider if you want some serious sports tracking and don't mind the heft.

Shopping for fitness tracker on a budget? Then look no further than the Fitbit Charge 2. This model performed exceptionally well, tying for the top score in our test with the Blaze and costing about $50 less. This is an exceptionally well-rounded tracker, excelling at basic fitness tracking and has several features focusing on your wellness. These include a series of guided relaxation exercises to help you unwind when you are too stressed out. This model is also much slimmer and stylish than the larger, bulkier trackers with built-in GPS and comes in an attractive variety of colors. This is definitely the model to consider if you are shopping on a slim budget and want to keep a fat wallet.

Heart Rate Monitor: Yes | Built-In GPS: Yes
Amazing display
Tons of trackable activities
Packed with sensors
Bulky
Mediocre looks

Tying for the second highest score of the entire group, the Garmin Vivoactive HR is an overall excellent fitness tracker, earning our Top Pick for Outdoor Activities award. This rugged and durable fitness tracker is rated to 5 ATM of water resistance and is packed to the brim with different sensors, including everything from an accelerometer to an altimeter. It has a ton of preloaded activity profiles for all of your different outdoor adventures and has some of the most detailed and comprehensive fitness data displayed after a workout that we have seen. It is a little on the pricey side and is a bit hefty, but it is still surprisingly comfortable to wear and has a decently minimalistic profile on your wrist. For those looking for some wearable tech to accompany them on all of their outdoor exploits, then this is the one for you.

Ready to venture off the beaten path but trying to save some cash? the Garmin Vivosmart HR+ scored very well in our tests, just barely being edged out of the top spots. Its performance is eclipsed by the Vivoactive HR in almost every aspect, but the Vivosmart HR+ still has some merit. It retails for significantly less than the Vivoactive HR and is a solid option for someone who is still looking for a rugged and waterproof fitness tracker with a built-in GPS module and is shopping on a budget. It also is decently smaller than the Vivoactive HR, but is still quite bulky. Regardless, the Vivosmart HR+ is a solid option for the outdoorsy adventure that is shopping on a tight budget.

Looking for the most detailed GPS stats available right on your wrist, or looking to leave the smartphone behind? The Spark 3 is a rugged, 5 ATM waterproof fitness tracker with a built-in GPS module and audio player. This model will display your route right on your wrist or allows you to upload .GPX files and shows your location relative to your planned route, helping you stay on track. This tracker also has up to 3 GB of onboard music storage and can pair directly with a pair of Bluetooth headphones. However, this model doesn't have the most interactive of an online community and the app isn't quite as full-featured as other brands.

Analysis and Test Results


Exploding in popularity in the past few years, fitness trackers and other wearable pieces of technology have become one of the new hot items. These are designed to improve your fitness by measuring your progress towards various goals and maximize your motivation by integrating you into a community of like-minded individuals. We spent a substantial amount of time researching these trackers, comparing specifications and features, and reading through user reviews and experiences to determine what qualities the best fitness tracker would have, and design a testing regimen to crown the award winners.

We bought the highest rated products currently available and put them through a veritable barrage of tests to see which one came out on top.
We bought the highest rated products currently available and put them through a veritable barrage of tests to see which one came out on top.

We split our testing process into five distinct metrics: Fitness Impact, Health Impact, Ease of Use, Ergonomics, and Display. Each model of tracker received a score in each metric, and these were combined to determine the overall score. We detail exactly what each tracker did well and where it struggled in the following sections.

The lineup of fitness trackers  ready to be assessed.

Fitness Impact


The most important metric in our test, and the primary reason that many people will purchase one of these products is to improve their fitness. We rated the products on how the community could motivate you, as well as what activities and workouts each device could track. While health and fitness are arguably the same thing, or at the very least substantially intertwined, we focused primarily on how well each tracker did at recording physical activities in this metric, leaving things like diet and sleep tracking for a separate metric. You can see how all of the products compared in the chart below.


We manually counted how many steps it took to walk a mile course with a mechanical tally counter, then compared it to each tracker on the same course.

To check the step count of each tracker  we manually compared with a tally counter over a mile walk.
To check the step count of each tracker, we manually compared with a tally counter over a mile walk.

After multiple trials for each tracker, we computed the average % error. We also tested the tendency to record false steps off random arm movements. Finally, we checked how each tracker did at monitoring a high-intensity cardio workout, a cycling workout, and if any models had special features focused on other physical exercises.

The Fitbit Surge was the top-scoring model in this metric, earning a 9 out of 10. This model has a built-in GPS, so it is exceptionally accurate at measuring distance walked or ran, as it is actually measuring it, not estimating off a step count. This built-in GPS is a great feature, as the ever-increasing size of smartphones has made it less and less convenient to bring these devices with you while working out, making it a challenge for those addicted to tracking every adventure they take. A fitness tracker with a built-in GPS allows you to still generate detailed maps and tracks of your day while leaving your large smartphone at home. This model did a good job at counting steps, but it wasn't the most accurate, averaging about 0.9% off the true count in our tests. This model also does a great job of tracking cycling, measuring the top speed, average speed, distance traveled, duration, and elevation changes.

We used a bike mounted cycling computer as a baseline to compare the cycling tracking on each product.

We particularly liked that you can pause recording in the middle of a workout to take a quick break, then resume again when you are ready.

The Garmin Vivosmart HR+, Garmin Vivoactive HR, Fitbit Blaze, and Fitbit Charge 2 all finished in a tie for the second highest fitness impact score with an 8 out of 10. These four models all won awards, and particularly excel at tracking physical exercises. The most accurate step counter out of all the wrist-mounted models we tested was the Vivosmart HR+, averaging a minuscule 0.2% discrepancy. However, this model was substantially more prone than the others to pick up false steps off random arm movements. The HR+ also has a built-in GPS module, making it perfect for tracking cycling or long runs.

The Vivoactive HR only averaged a slightly higher discrepancy when it came to step counting accuracy — 0.47%. This model has a whole host of different trackable activities and has some of the most detailed fitness stats that we have seen in these products. It has a built-in GPS, as well as a ton of other sensors, making it an awesome choice for tracking cycling or other outdoor activities.

Both the Blaze and the Charge 2 can connect to your phone to add GPS capabilities — a great feature, but only if you are ok bringing your mobile device along with you. Both of these models have similar recording metrics for cycling, or with other workouts. In addition, the Blaze does have Fitstar — three-part workouts that last about 20 minutes if you need some added inspiration. We also found that the Blaze was slightly more accurate than the Charge 2 when it came to counting steps, about the same as the Surge.

Next in the rankings were the TomTom Spark 3, Garmin Vivoactive 3, and the Fitbit Charge HR, all earning a 7 out of 10. The Charge HR is exceptionally similar in fitness performance to the Charge 2, but it lacks the ability to pair with your phone's GPS, thus bringing down its score slightly.

The TomTom is exceptionally accurate at tracking steps and distance. It also does a solid job at tracking a whole host of other activities.

However, this model is severely deficient at allowing you to compare and compete with your friends — the worst of the group. It also lacks the ability to track flights of stairs climbed.

The Vivoactive 3 is a smartwatch-style fitness tracker. It has a ton of activity profiles for every activity you might do, such as ski, snowboard, XC skiing, SUP, yoga, or golf — to name just a few. It has a built-in GPS module, allowing it to do a great job at tracking different workouts and is very accurate at counting steps.

With a large selection of activities you might find one that best suits your less mainstream interests.
With a large selection of activities you might find one that best suits your less mainstream interests.

Following these two trackers was the Garmin Vivosmart HR, Garmin Vivosmart 3, Fitbit Alta HR, Garmin Vivosport, and the Polar A360, all earning a 6 out of 10. The Vivosmart HR is the non-GPS version of the HR+, performing similarly, but loses some accuracy at counting steps. This model also lacks a ton of the cycling metrics, only monitoring your heart rate and timing the duration of the activity. This model also tracks flights of stairs, but it was slightly more inaccurate than the Fitbit's in our tests, adding a phantom flight of stairs.

The Vivosmart 3 is alright at tracking steps and counting stairs climbed, but it is a little deficient when it comes to tracking other activities, with a limited set of data. The Alta HR is even worse at dealing with other activities, but it does have a substantially better online community — like other Fitbits — for fun challenges and competitions.

The Polar wasn't as accurate at step counting, lacked lots of customization available to other models, and only tracked basic stats: calories burned, heart rate, and duration. However, this model does have a ton of training profiles you can add for a whole host of activities, such as kitesurfing, table tennis, or backcountry skiing, though it is worth bearing in mind that the Polar doesn't change what it tracks for each activity, just logs that you did a different exercise.

The Polar app has plenty of different profiles to log your activity under.

The Garmin Vivosport has a built-in GPS module, allowing to accurately track and monitor a variety of metrics while you are working out. It is very accurate at counting steps, though it did show a slightly larger discrepancy from the true manual count than the Vivoactive 3. However, it does have a much smaller set of activity profiles to choose from and wasn't terribly accurate at tracking flights of stairs climbed in our tests.

Rounding out the bottom of the pack, our last 5 trackers all scored 5 or below. The Garmin Vivofit 3 is limited to tracking steps and timing activities, lacking the sensors for heart rate or stair climbing, enough to merit it a 5 out of 10. The Misfit Shine 2 earned the same score, similarly only tracking duration and steps, but it has a few more activities that you can classify your physical activities under in the app than the Jawbone UP Move. The Jawbone and the Huawei Band 2 Pro both earned a 4 out of 10, getting docked for their step counts that varied off of the true count by much more than other models. The Jawbone was either dead on or way off, with no middle ground, while the Huawei was about 3% off of the true count in our tests.

The Band 2 did poor matching up to our manual step count over a mile.
The Band 2 did poor matching up to our manual step count over a mile.

Finally, the Striiv Bio 2 finished last, with a dismal 3 out of 10. It tracked steps accurately, but that's about all it did, proving unreliable at tracking anything else accurately.

Finally, we looked at the companion apps for each manufacturer, as different models utilize the same app. The Fitbit app led this category with its weekly emails including your stats for the previous 7 days, as well as your top 3 friends on the step count leaderboard. The app has non-competitive "Adventures", where you can digitally walk along a path to a point of interest, using your steps. There are also competitive challenges you can undertake against yourself or your friends.

Next was the Garmin Connect app, having a simpler set of features allowing you to track your progress over the past 7 days, month, or year, and allows you to opt into weekly challenges with people in your step range. The Jawbone app followed, allowing you to view your trends and duel with your friends, but lacked even more functionality than the Fitbit or Garmin apps. Rounding out the bottom were the apps from Misfit, Polar, and Striiv — each of these apps only allowed you to view your past progress, not really allowing you to challenge your buddies at all.

Health Impact


The next highest weighted metric in this product category is the health impact of each tracker. To assess this, we started with whether or not the tracker could monitor heart rate, and how accurate it was compared to a chest strap heart rate monitor. Then, we looked at what aids in dieting each model could provide, what other lifestyle changes it could help you implement, and whether or not it could track sleep and wake you, as well as it there were any other health-specific features. You can see which models scored the best in the chart below.


The Charge 2, Alta HR, Vivoactive HR, Vivosmart 3, and the Blaze led this metric, all earning a 7 out of 10. These models all have automatic sleep tracking, as well as a vibration wake alarm to gently wake you and leave your partner undisturbed. Our tester felt that the sleep stats reported by the Fitbit brand trackers were very close to his recollections of the night, in terms of the number of times woken up. We found the Garmin brand trackers to be a little more temperamental when it came to sleep monitoring, with it failing to log any data at all plenty of times. The Blaze and the Charge 2 were off an average of 23 and 16 bpm from the chest strap heart rate monitor, with larger discrepancies occurring the more active you are — and higher your heart rate was.

The Blaze did an alright job at monitoring heart rate  though its accuracy dropped the higher your heart rate was.
The Blaze did an alright job at monitoring heart rate, though its accuracy dropped the higher your heart rate was.

The Alta HR didn't perform terribly well in our heart rate test, averaging about 34 bpm off of the chest strap. On the other hand, the Garmin models — the Vivoactive HR and the Vivosmart 3 scored very well in our test, only averaging about 8 and 9 bpm off of the chest strap, respectively.

We also found the heart rate sensor to be quite accurate in our tests.
We also found the heart rate sensor to be quite accurate in our tests.

You can scan or search for food to help maintain diet in the Fitbit app, as well as monitor hydration. These models both offer reminders to move every hour if you have been too sedentary, and the Charge 2 has the unique feature of guided 2 or 5-minute breathing sessions to help you relax.

Breathe in....
And breathe out.
 

Trailing slightly behind the leaders, the bulk of the trackers all earned a 6 out of 10 in this metric, including the Alta, Charge HR, Surge, Vivosmart HR, Vivosmart HR+, Misfit Shine 2, Vivoactive 3, Vivopsport, and Polar A360. All of the Fitbit models were excellent at aiding in tracking caloric intake, though only the Charge HR and the Surge had the capabilities to read your heart rate. These models were both less than 25 bpm off the chest strap, on average. The Alta lacks this ability but does vibrate to alert you that it is time to get up and move.

The HR and the HR+ were much more inaccurate than the Fitbits in our test, averaging 51 and 31 bpm off, respectively. These models also require you to use a third-party app, MyFitnessPal to track your diet, rather than their companion apps. However, these models have the best reminders to get up and move, with a movement bar on the left side of the screen that builds up the longer you have been stationary, requiring a proportional amount of exercise to remove it. These models both have automatic sleep tracking and can act as an alarm clock.

The need to move bar  on the left side of the screen  will fill up the longer you have been sedentary  and takes a proportional amount of activity to reduce it.
The need to move bar, on the left side of the screen, will fill up the longer you have been sedentary, and takes a proportional amount of activity to reduce it.

The Vivoactive 3 and the Vivosport both were relatively subpar at monitoring heart rate, varying significantly from the measurement we took with the chest strap heart rate monitor. These models both did an alright job sleep tracking and required you to use a third-party app to track calorie intake, but both have a movement bar to remind you to get up and get active after you have been sitting for too long. This pair also has some basic sleep tracking abilities and a vibration alarm clock.

The Misfit Shine 2 lacks heart rate monitoring, though you can use the app on your phone to estimate it, and requires you to use the same third-party app to monitor calories, MyFitnessPal. This model does offer movement reminders with a customizable duration, anywhere between 20-120 minutes in 20-minute increments. The Misfit can also track your sleep, initiated through a button press. The Polar A360 was actually the most accurate at monitoring heart rate in our tests, averaging only 6 bpm off of the chest strap — definitely making this a model to think about if heart rate is your main priority, though you may just be better served with a chest strap monitor if that is the case. The Polar uses MyFitnessPal as well to track calories and lacks any sort of movement reminders.

Exceptionally accurate at heart monitoring  the A360 fell flat in our other testing metrics.
Exceptionally accurate at heart monitoring, the A360 fell flat in our other testing metrics.

The Spark 3, Huawei Band 2 Pro, and Garmin Vivofit 3 all earned an average 5 out of 10 when we evaluated their health impacts. The Spark 3 and the Vivofit 3 both lack heart rate monitoring, with the Spark 3 more effective at tracking calorie intake, and the Vivofit 3 better at reminding you to get up and move. The Vivofit 3 will also automatically track your sleep.

The Spark 3 has a heart rate monitor that works reasonably well but offers very little in terms of help implementing a lifestyle change or a diet. While it does estimate calories burned, it does nothing to monitor caloric intake and it doesn't have any sort of reminder to get up and move when you have been stationary for too long. This model also did an unremarkable job at tracking your sleep, only showing the duration with no additional data.

The Huawei Band 2 Pro had a relatively terrible performance in our heart rate monitoring test, averaging by over 70 bpm off of our chest strap control heart rate monitor. This tracker also uses MyFitnessPal to track calorie intake, like the Garmin's, but it does have a notification to alert you to get up and move if you have been stationary too long.

The Striiv Bio 2 and the Jawbone UP Move both scored somewhat poorly in this metric, earning a 4 and a 3, respectively. The Bio 2 measures heart rate, but was the least accurate out of our testing, averaging 61 bpm off of the chest strap. This tracker lacks an alarm to notify you to move and requires you to use MyFitnessPal to track dieting. You initiate and stop sleep tracking through the app, and it gave us an endless amount of problems. The Up Move does not monitor heart rate in any way or remind you to get up and move around. This model can track sleep using the included wristband, though it's not automatic, and requires the same third-party app to count calories.

Ease of Use


Next, we analyzed how easy each tracker was to use. These products are meant to be worn daily, and something that is difficult to use isn't exactly conducive to wearing on a daily basis. We evaluated the battery life, how intuitive the device and app was, how difficult it was to sync data from the device to the app, how hard it was to put on the device, and whether or not it was water resistant. The following chart shows which models stood out, and which ones fell flat.


Two trackers led this set of tests, the Charge HR and — surprisingly — the Shine 2, all earning an 8 out of 10. The Shine relies on a coin-cell battery, lasting for a claimed 6 months, but does require you to change the battery when it dies, rather than re-charge it. This model syncs well, taking only 6-8 seconds, and happens as soon as the app opens up. The app shows you your fitness stats by day, week, or month, and shows a little graph.

There aren't really any menus to navigate on this device, as it only has a ring of LED's, as a display. The Shine 2 is waterproof to 50 meters, and it is easy to put on. The Charge HR has a short battery life, only lasting for up to 5 days. This model's band has a nice stiffness to it, making it easy to put on.

The main bulk of the trackers closely followed, with the Alta, Alta HR, Blaze, Charge 2, Surge, TomTom Spark 3, and Vivofit 3 all earning a 7 out of 10. The Fitbit models sync quickly, and have the easiest to use and most intuitive app, clearly displaying all the relevant information.

The Vivofit 3 uses a coin-cell battery, lasting for up to one year before needing replacement. This model is rated to up to 5 ATM of depth, and the single button interface made it easy to navigate through the menus. The Garmin app isn't quite as intuitive as the Fitbit, with the sheer amount of information causing it to be slightly overwhelming at first. This model was also the most reliable and easiest to pair out of the Garmins.

The Surge lead the pack of Fitbits in terms of battery life, claimed to last up to 7 days, but only if the GPS is turned off. While using the GPS, the battery life is reduced to 10 hours. The other Fitbits last for up to 5 days, and all use a proprietary charger. The Blaze and the Surge were both equally easy to navigate through the menus on the device, much better than the slightly finicky Alta and Charge 2. None of these four models are waterproof, only water-resistant, and only the Alta gave us some difficulties with its clasp when putting on.

The Alta HR uses a watch-style clasp, making it substantially easier to put on than the Alta. The Alta HR also has an improved battery life, but is a little less water resistant, no longer rated for wearing in the shower.

The TomTom Spark 3 has a solid battery life, with the manufacturer stating it can last for up to 3 weeks with normal activity tracking and 11 hours when using the GPS. This model is also water resistant to 5 ATM, very easy to put on, and has a handy directional pad to navigate between menus.

However, while this model synced to a smartphone reasonably well, we found the companion app to be underwhelming. We had quite a few issues with it crashing and it was much harder to use than the Fitbit app and had a reduced set of features when compared to Garmin's Connect app.

Both the Vivoactive 3, Vivosport, Vivosmart HR, Vivoactive HR, and the Vivosmart HR+ all earned a 6 out of 10, losing a few points for their shorter battery life and slightly overwhelming app. These models last for up to 5 days, with the HR+ only lasting for 8 hours and the Vivoactive HR only lasting for 13 hours with the GPS enabled. The Vivoactive 3 and the Vivosport are similar, lasting for up to 7 days with normal use and 13 and 8 hours respectively when the built-in GPS module is being used. As mentioned above, the Garmin app is a little confusing, and we found that some of these models tended to have some syncing issues in our tests, tending to display some sort of error at first, but then syncing successfully. There weren't many on-device menus to navigate through on this group of trackers, but they were straightforward in their simplicity. All of these are easy to put on, and rated to 5 ATM of depth.

The Huawei Band 2 Pro, Jawbone UP Move, Polar A360, Vivosmart 3, and Striiv Bio 2 all were of average difficulty, earning a 5 out of 10. While the Jawbone has a great battery life of up to 6 months on a coin cell, it was very finicky to connect with the app and the app was overly complex and unintuitive for such a simple device. The Jawbone has no menus to navigate on the device — lacking a screen — and is rated as splash-proof only. The A360 has a good battery life of up to 14 days but takes around a minute to sync data with your phone. We struggled a little to put this model on, and it is only rated for accidental splashes. The Vivosmart 3 is waterproof to 5 ATM and is very easy to put on, but we found it to be quite confusing to navigate among the menus on the device and it has a somewhat reduced battery life compared to its peers. The Bio 2 has a claimed battery life of up to 30 days, but we found it depleted extraordinarily fast in our tests. This tracker's app also felt a little outdated, and only had minimal useful information.

The Huawei Band 2 Pro has a mediocre battery life and an abysmal app. There wasn't a ton of data displayed and we had a ton of syncing issues, such as lost data in our tests. It's fairly easy to put the Huawei on or take it off and it's water resistant to 5 ATM.

Ergonomics


Ergonomics was a much simpler test for these products, split into three aspects: comfort, aesthetics, and profile design — the likelihood that the fitness tracker would become snagged when performing various common tasks, such as putting on a windbreaker or a backpack. The chart below shows which models were the most comfortable to wear, and which ones were too bulky for our taste.


The majority of the models tied for the top spot, with the Alta, Alta HR, Vivosmart 3, Vivofit 3, UP Move, TomTom Spark 3, Shine 2, Garmin Vivosport, Huawei Band 2 Pro, and Bio 2 all earned a 7 out of 10 in this metric. These models all have a relatively low-profile, making it easy to put on a backpack or a light jacket. The clip-on UP Move was the most comfortable and least obtrusive of this bunch, closely followed by the low-profile Shine 2. The Bio 2, Spark 3, Vivofit 3, Vivosmart 3, Vivosport, and the Huawei were next, being decently comfortable and having lower profiles. These were followed by the Alta and the Alta HR, which had very low profiles, but still weren't the most comfortable to wear.

The Alta and Alta HR are, in our opinion, the most visually stunning of that group, available in an attractive variety of colors. The Huawei is a close second, essentially being a visual clone of the Alta. The TomTom, Vivofit 3, Vivosmart 3, and the Bio 2 are pretty run of the mill for these products, all black plastic rectangles of varying dimensions. The Vivosport improves on this, having a slightly sleeker, rubberized exterior available in a variety of colors. The UP Move comes in a few colors, but is essentially a small disc clipped to your pocket — so there is not too much potential for a striking fashion statement. The Shine 2 received mixed views from our panel, with people either loving it or hating it, but it's ultimately up to you if it matches your style.

Next were the Vivoactive 3, Vivosmart HR, Vivosmart HR+,Vivoactive HR, and the Charge 2, all earning a 6. These models were all similarly comfortable, though the HR+, Vivoactive 3, and the Vivoactive HR have a larger profile due to the built-in GPS module. The Vivoactive HR does manage to maintain a much lower profile than the others, hardly ever snagging on anything. The other three models were all equal when we tried to put on a backpack or jacket, only experiencing some slight snags. The Vivosmart HR, HR+, and the Vivoactive HR were equal and average when it came to appearance, but the Charge 2 and the Vivoactive 3 stood out as being much more visually striking.

The A360, Blaze, and Charge HR all were about average in ergonomics, deserving a 5. The A360 is mediocre across the board, along with the Charge HR. The Blaze is the closest to a smartwatch out of the bunch, with a larger, higher-resolution display and interchangeable bands to match any style. However, this model is quite large, and wasn't the most comfortable, especially for those with more petite wrists. However, this tracker definitely qualifies as visually appealing.

Finally, the Fitbit Surge rounded out the bottom of the pack in this metric. This model is large. Period. It has the larger profile common among the built-in GPS models and is of about average comfort to wear. It comes in a handful of colors, and like other models, a rectangle of molded plastic — making neither stunning or ugly. What really sets this model back is its elevated profile, which managed to get caught on everything throughout our tests.

The Surge is an exceptionally large tracker...but also has an exceptional set of features and functions.

Display


The final rating metric that we looked at for this category was the quality of the display. The following graphic shows which models had the nicest displays, and which ones fell short.


We evaluated the clarity of information displayed, whether or not the tracker could substitute for a watch, how visible the screen was in different lighting conditions, its responsiveness, what notifications could be displayed, and what other information was shown on subsequent screens. All of these models enter a sleep mode when you are not adjusting settings on them to conserve power, so we defined responsiveness as how easy it was to wake up the device to initiate a workout or look at your progress, and how easy it was to control the device through the touchscreen and buttons.

Eight models tied for the top score in this set of tests, all earning a 9 out of 10. The Vivoactive 3, Vivosport, Blaze, Surge, Polar A360, Vivosmart HR, Vivoactive HR, and Vivosmart HR+ all have exceptionally nice displays, with a distinguishing factor being how easy all of these models were to read in direct sunlight. While all of these models can receive text and call notifications, all of the models from Garmin are able to receive email notifications as well.

The five models from Garmin and the A360 were also slightly more responsive than the Fitbit models, something to consider if you become easily frustrated by a finicky tracker. This primarily presents itself by not being able to wake the device up, or by having a touchscreen that is unresponsive to commands. This can actually be a surprisingly differentiating factor between models, as the less responsive ones were incredibly infuriating over time.

Next up, the TomTom Spark 3 and the Fitbit Charge 2 both scored an 8 out of 10. The Charge 2 mainly getting knocked down by its lack of visibility in bright sunlight, but sharing all the other features that the top scoring models had. The Charge 2 also has calendar event notifications, to ensure that you never miss an appointment. The predecessor to the Charge 2, the Fitbit Charge HR earned a 7 out of 10. This model has a much smaller screen but is very responsive, both to button and touchscreen presses. This model shares the similar problem of not being quite as easy to read in sunlight, and lacks text notifications, only calls.

The Spark 3 had an exceptionally easy to read display that was highly visible in direct sunlight. However, it lacks notifications entirely, severely dropping its score in this category. It also does not have a touchscreen, instead relying on a directional pad below the display. This input method is highly responsive but takes a little bit of time to become familiar with.

The Spark 3 had one of the easiest to read displays of the entire group  especially in bright light.

Tying with the Charge HR and the TomTom, the Fitbit Alta, Alta HR, and the Garmin Vivofit 3 all earned 7 out of 10 as well. This Alta and Alta HR do a much better job at notifications, displaying text, call, and calendar events, but both are dismal when it came to responsiveness. This pair of models requires the most delicate of touches in a specific spot to cause it to wake and caused us an endless amount of frustration. The Vivofit 3 is highly responsive, and extremely visible in bright light, but to our dismay, lacks any sort of backlight, making it impossible to see in the dark. This model also lacks any notifications.

Next, the Huawei Band 2 Pro earned a 6 out of 10 for its display. This tracker isn't very easy to read in bright conditions, hurting its score slightly. It's not terribly responsive, but it does get smart notifications and showed a decent amount of basic fitness data.

Finishing out the bottom of the pack in this metric was the Jawbone UP Move, Misfit Shine 2, Garmin Vivosmart 3, and the Striiv Bio2, all earning a 5 out of 10. Both the Misfit and the Jawbone lack traditional screens, foregoing them in favor of a ring of LEDs. While this severely limits the amount of information conveyed, these models still convey the current time and progress. These models are responsive, and the Misfit will vibrate when you receive a call or text. The Striiv showed the time and some fitness stats, but it was very hard to read — the worst out of the bunch and was incredibly unresponsive. This model supposedly can receive notifications, but we couldn't successfully get it to work. This model does show your step count, distance, calories burned, and active time on further displays. The Vivosmart 3 is exceptionally difficult to read and is not very responsive, though it does display a decent amount of data and notifications.
