The best fitness trackers are good tools for getting more active, getting more sleep, and getting more insight into your overall health. They can help you track your progress and offer guidance on how hard you should be pushing yourself, too.
As exercise-oriented wearables, fitness trackers can measure your heart rate, read your blood oxygen levels, accompany you swimming and tell you if you’re well-rested. When you’re not working out, some can be used to pay for groceries, play music, answer texts, and much more.
With so many devices, choosing one of the best fitness trackers or fitness watches for your needs can be tricky. We put dozens to the test, spending hours on the treadmill, running, biking, swimming — even sleeping — to see which excel, and which couldn’t make it past the starting block.

What are the best fitness trackers?
We think the best fitness tracker for most people is the Fitbit Charge 4. For $149, it’s not all that expensive, and features a built-in GPS and extensive health tracking. The Fitbit Charge 4 also sports improved sleep tracking, wireless payment support and on-device Spotify controls. Plus it’s swim-proof and has a bright touchscreen display that responds instantly to swipes and taps. We’d even say, right now, it’s still a better pick than the Fitbit Charge 5, which has an ECG monitor and a Daily Readiness Score, but neither are available on the tracker right now.
Looking for something with more features? The Fitbit Sense is one best fitness trackers that’s also one of the best smartwatches. It offers advanced health analysis, a dedicated app store and the Alexa voice assistant on-board. Long story short, it has more features than the Charge line, so it’s more comparable to the Apple Watch. We think it’s a better overall wellness tool than the Apple Watch, though.

The Fitbit Charge 4 is our top pick among the best fitness trackers and fitness watches because it introduces the key feature we missed on the Charge 4: GPS. The Charge 4 sync with a smartphone to show you a map of your runs, hikes and other outdoor activities. You’ll also see data for pace, elevation, heart rate zones, and calories burned. Even better, the app overlays this information along your route, so you can see what parts of your venture made you huff and puff.
The Charge 4 uses an SpO2 pulse oximeter sensor to better help you understand sleeping patterns, too. Plus the Charge 4 is the first of Fitbit’s fitness trackers to have contactless Fitbit Pay capabilities. If you’re looking for a well-rounded wearable with a broad collection of features, this is the one to get. Our Apple Watch Series 3 vs. Fitbit Charge 4 and Fitbit Versa 2 vs. Fitbit Charge 4 face-offs also details the benefits you’ll get with a traditional fitness tracker over a smartwatch.

The Fitbit Charge 5 is Fitbit’s latest tracker and it has a number of exciting features, usually reserved for Fitbit’s more expensive trackers, an ECG heart rate monitor being one. The bright, always-on color touch screen is a massive improvement to that of the Fitbit Charge 4 — it is easy to read in bright sunlight and is great to use during a HIIT workout or on a hike, although we found the lack of physical buttons made it a little fiddly to navigate around when running.
The Fitbit Charge 5 also has Fitbit’s new ‘Daily Readiness Score’ feature, which gives you an idea of how ready you are for a big workout, based on three different metrics — fitness fatigue (activity), heart rate variability (HRV), and recent sleep.
If you’re looking for a tracker that looks beautiful against your wrist, is easy to read in the bright sunlight and has some impressive features for the price tag, this is a good buy. Also, if you’re using a Fitbit Charge 3 or older, the upgrade is worth it for the color screen alone.

The Fitbit Sense is the company’s top-shelf smartwatch that comes with more advanced health and wellness features that the Versa line. Not only does it have an FDA-approved ECG sensor and blood oxygen reading, but the Sense has the ability to measure electrodermal activity and skin temperature, too.
As one of the best fitness trackers, the Sense works with both iOS and Android, and comes with on-board GPS, a native app store, Alexa and more. No longer is Fitbit just a brand with products for tracking our steps: Fitbit devices like the Fitbit Sense make for excellent smartwatches, too.

Garmin makes the best sports watches you can buy, and the Forerunner 245 is one of our favorites. There aren’t a lot of bells and whistles, but this running watch is small and light with built-in GPS and a colorful screen that’s easy to see in bright sunlight.
Even better is that the Forerunner 245 has onboard music storage, so you don’t need to carry a smartphone with you if you want to listen to tunes while you run. The 245 also calculates your V02 max score and offers a recovery advisor to let you know how long to rest between runs. This watch also lasts for about a week of workouts on a charge, which isn’t bad for such a fully-featured GPS watch. However, Garmin’s menus, on both the watch and its app, can be a bit confusing.

Whether you’ve got a Samsung phone or not, the Samsung Galaxy Watch 4 is an impressive piece of kit for anyone looking to keep track of their health from their wrist. There’s a 3-in-1 health sensor for measuring heart rate, taking ECGs and reading body composition – in fact, it’s the first major smartwatch to offer bioelectrical impedance analysis (BIA), to help you manage your health goals.
Even if you’re not interested in your body composition, the watch has all you need to track your daily activities, as well as automatic workout-tracking for when you forget to press start. The downside with this watch is the battery life, which we found didn’t last the full 40 hours Samsung suggests with GPS and activity tracking on, but unless you’re heading out for an ultramarathon, you shouldn’t let this put you off.

The Amazfit Band 5 is a $50 fitness tracker that promises many of the marquee features found in this year’s premium smartwatches, but at a fraction of the price. It has blood oxygen (SpO2) reading, stress monitoring, high heart rate alerts, Amazon Alexa built-in, sleep tracking and several other tools found in high-end offerings.
In our testing, the fitness and sleep tracking on the Amazfit Band 5 were good, not great, but respectable for the low cost while still offering more than other trackers of its price. Better yet, the 15-day battery life meant we didn’t need to worry about charging it all the time.

As one of the best fitness trackers, Amazon Halo is a both a $99 activity tracker and $3.99 per month service that provides a holistic catalog of health metrics and ‘labs’ for helping you reach wellness goals. Although it’s an in-brand Amazon device, Alexa is surprisingly absent. Instead, the band’s built-in mics listen to how you speak and gauge the emotions you convey based on your tone. You can see how you sound to others, plus how well you sleep and how many activity points you’re banking, in the connected Halo app.
The Amazon Halo app is also how you capture 3D scans of your body which, using AI, determine your body fat percent and show you with a slider what you might look like with less fat. Plus the large library third-party labs introduce a “choose your own adventure” element to improving your overall wellness.

Amazon also announced the Amazon Halo View is coming soon — here’s what we know so far.
The Fitbit Inspire 2 is one of the best Fitbits for those on a budget, as well as one of the best fitness trackers overall. In essence it’s a slimmed-down, slightly stripped-down version of the Charge 3, which makes this ideal for those who are interested in tracking their steps and sleep.
Similar to the Charge 3 and Charge 4, the Inspire 2 has an OLED touchscreen display (though a bit smaller here), a heart rate monitor, smartphone notifications, swim tracking, and sleep-tracking too. One shortcoming of the Inspire HR is that it doesn’t have GPS built in, but you’re able to link it to your smartphone and use its GPS to accurately track your outdoor activities, if you so wish.
The Garmin Venu Sq has several of the features found in the $349 Garmin Venu —including GPS, blood oxygen (SpO2) readings, mobile payments and optional music storage — but at a more accessible price of $199. That’s what makes the Venu Sq one of the best fitness trackers you can get for under $200.
It might not be the most attractive watch (though the squircle shape is familiar), but it’s certainly capable. The Garmin Venu Sq has GPS, GLONASS, and Galileo satellite-tracking capabilities, as well as the ability to track a variety of gym exercises. It’s a good hybrid choice for people who workout both outdoors and indoors.

While the Apple Watch Series 6 might be a cheaper buy, the Apple Watch Series 7 is the most usable smartwatch yet and is well worth the upgrade in our eyes. (That said, if you’re looking to save, the Series 6 is still a brilliant buy — we even gave it an award in our 2021 Tom’s Guide Awards for Health and Fitness. From a fitness tracker perspective, it’s a brilliant piece of tech to have on your wrist. We loved the always-on display and the collection of health features, with an even brighter screen and added blood oxygen (SpO2) reader
The watch has 14 different quick-start workout modes, which include running, cycling, walking, and strength training, plus you have the option to add new workouts in the Workout app. It added Tai Chi and automatic outdoor cycling tracking this year, meaning it can detect when you’ve hopped on your bike and enable a workout. The cycling algorithm has also been adjusted to accommodate metrics for the best electric bikes, which are less strenuous to ride than regular bikes.
Apple also launched Apple Fitness Plus last year, which gives you access to hundreds of workouts.
The downside with the Apple Watch is the 18-hour battery life, which is a lot less than some of the other trackers on this list.

The best fitness tracker for sleep tracking is the Fitbit Versa 3, the next-generation of the Fitbit Versa 2. The Versa 3’s standout upgrade is on-board GPS. Now, even when you leave your phone at home, the Versa can (finally) track your location during outdoor exercise. A curvier, larger display is welcome, too.
Plus the Versa 3 has gained a great motivational workout feature, Active Zone Minutes. Introduced with the Charge 4, Active Zone Minutes monitors the time you spend in the fat burn, cardio or peak heart-rate zones while exercising. Your goal is to earn the AHA’s and WHO’s recommended 150 Active Zone Minutes each week.

While it’s one of the most stylish fitness trackers there is, the Garmin Vivoactive 4’s attributes are more than skin deep. That’s because this device has excellent GPS, a heart rate monitor, sleep tracking, and an NFC chip so you can use it for mobile payments.
We also liked that the Vivoactive 4 has on-screen animations for workouts including yoga, Pilates, cardio and strength-training exercises. It also has respiration tracking and a pulse oximeter for tracking blood oxygen saturation levels, as well as on-board music storage. Its estimated battery life of seven days is also pretty good, but that will decrease the more you use GPS.

How to choose the best fitness tracker for you
When buying a fitness tracker, you should first evaluate your needs. What do you want to track? If you’re only using it at the gym to count your steps and your heart rate, a simpler, less expensive fitness tracker will suit you fine.
If, however, you plan to do more outdoor activities, such as running or biking, you may want a fitness tracker with built-in GPS, so you can more accurately see where you’re going, and where you went. Dedicated runners and athletes will want to check out our best GPS watches page, too.
If you plan to use the fitness tracker for swimming, you’ll want to make sure it’s not only waterproof, but that it can also track your laps in the pool.
Many of the best smartwatches have fitness-tracking capabilities, too, and have additional features such as responding to text messages and paying for purchases. But there are trade-offs. However, smartwatches as a whole tend to be more expensive and have shorter battery life than dedicated fitness trackers.
How we test the best fitness trackers
For each new fitness tracker, we evaluate its hardware design and comfort; you need to be able to wear the device all day, and we’ve found that some larger trackers don’t fit well on smaller wrists. If the device has a touchscreen, we look to see how readable it is, especially in bright sunlight. We also examine how easy it is to navigate the fitness trackers’ menus; you don’t want to have to dig through multiple screens to change your music if you’re out running.
We also evaluate features such as step counting and sleep monitoring, distance calculations and when applicable, GPS and heart rate accuracy. And, we see how well a manufacturer’s battery life claims hold up in real-world testing.
Finally, we test how well a device pairs with its companion app, and evaluate the experience of using the two together. We also look to see what features the device’s app supports, such as coaching and diet tracking, and if it can sync data with third-party apps, such as MyFitnessPal.
