Fitbit is the original fitness tracker. Although the wearable world has been flooded with new brands and tracker categories (ahem, smart rings) over the last two decades, Fitbit's devices are still some of the most dependable, user-friendly, and affordable options out there. Whether you're aiming to up your daily step count, improve your sleep, or train for a half-marathon, there's a Fitbit that fits your needs and budget.
Fitbit was launched in 2007 and purchased by Google in 2021, but the change in ownership seemingly didn't affect much for the brand (other than the Google Pixel watch getting a major upgrade by integrating Fitbit's technology). Its health and fitness trackers still offer long multi-day battery life, seamless compatibility with both iOS and Android, and access to Fitbit's well-established app, which stores all your data — years' worth, for brand loyalists — in one place.
Fitbit has six main fitness and health tracker families, but there are really only three that we'd consider the best picks for most people. Our top pick as the best Fitbit for most people is the Fitbit Charge 6. It's an exceptional health and fitness tracker offering multi-day battery life, health-monitoring tools, and comprehensive activity tracking in a smartwatch. For a budget option, our first recommendation is the Fitbit Inspire 3, a worthwhile entry-level wearable with basic health and fitness tools for well under $100.

Best overall
The Charge 6 by Fitbit has a more expansive feature set than the budget-friendly Inspire 3 for fitness, whether you're an amateur or enthusiast. While it's a pricier option, it's still amazing value for such a capable fitness tracker.
- Premium build with bright and colorful display
- Fast and accurate GPS
- Long battery life
- Advanced heart and stress sensors
- Can't make or receive calls
- No altimeter for stairs climbed tracking
- Some advanced features behind Premium paywall
Whether you're looking to increase your daily step count, track your sleep, or train for a race, the Fitbit Charge 6 is the best Fitbit for most people.
The Charge 6 is a kind of "smartwatch-y tracker": It's not a smartwatch, but it does have features like Google Maps, Google Wallet, and the ability to display messages on your wrist. That said, its screen is smaller, and its core focus is helping you achieve your health and fitness goals.
It offers the most accurate heart rate tracking of Fitbit's entire lineup, especially during intense interval workouts. It also features built-in GPS, electrocardiogram (ECG) sensors to assess any heart rhythm irregularities, electrodermal (EDA) sensors to assess stress levels, blood oxygen tracking, and all-day stress tracking (though you'll need a Fitbit subscription to access the coaching side of how you can improve any of these numbers).
The Charge 6 is compact, lightweight, and water-resistant, making it comfortable to wear while working out, in the shower, or sleeping. The display doesn't take up your whole wrist but is large enough to read at a glance. Its battery life stretches up to six days (shorter than the Inspire but longer than the Versa). And while you'll get text and app notifications, the Charge 6 isn't trying to replace your phone — it's a tracker first, smartwatch second.
This is the best choice for people who want a range of health and fitness features day in and day out without the bulk or distractions of a full smartwatch.
Best budget
The Inspire 3 may be one of Fitbit's most basic watches, but it still packs a powerful fitness-tracking punch with tons of trackable activities, advanced health features like skin temperature sensing, and a comfortable, lightweight design.
- Unrivaled battery life
- Comfortable to wear, even over long workout sessions
- Advanced health and fitness tracking
- No built-in GPS
- Small screen may not be preferable to some users
- Might be too basic for some users
The Fitbit Inspire 3 is a great intro fitness tracker. If you are just getting into a new health or fitness routine and want the basics of a fitness tracker without all the frills — or the triple-digit price tag — we love the Inspire 3. In fact, this is the tracker I got my mom for Christmas when she said she wanted to make sure she was walking enough and sleeping well. It has just enough features to provide value without being robust and overwhelming.
You get a lot for a relatively low price. For $100 or less (it's often on sale), it provides 24/7 heart rate monitoring, step counting, blood oxygen tracking, and automatic workout detection. In app, it also offers stress management tools like a stress management score, though this comes from a combination of metrics like heart rate, activity levels, and sleep patterns, versus the Inspire and Versa's more advanced EDA sensors. With a premium membership, you'll also get access to Fitbit's library of mindfulness sessions and deep breathing sessions. To improve your sleep, the Inspire 3 tracks sleep stages, duration, and heart rate variability and uses all of these to provide you with a daily sleep score. You'll also get daily readiness scores and personalized activity reminders on your wrist.
It's slim, modern-looking (thanks to a bright, colorful AMOLED display), and built for all-day comfort, even while you sleep. It's also compatible with a range of the best Inspire 3 bands to change its look slightly.
It cuts corners with no built-in GPS — you'll need to carry your phone to track distance — and no smartwatch features like on-wrist messages or music control. But thanks to Fitbit's robust technology, it still delivers all the aforementioned basics with surprising accuracy.

Best mid-range
The Fitbit Versa 4 disappoints as a fourth-generation smartwatch as it lacks third-party app support, has issues with fitness tracking, and doesn’t allow for music playback.
The Versa 4 is the closest thing Fitbit makes to a traditional smartwatch, with a large AMOLED display, physical button, and the ability to take Bluetooth calls and see notifications at a glance.
Functionally, it shares a lot with the Charge 6 — including blood oxygen monitoring (SpO2), sleep tracking, stress data, and built-in GPS. But the Versa 4 comes in a more traditional smartwatch aesthetic with its large, square screen, and has the ability to answer phone calls on-wrist.
Fitbit technically has two other smartwatches: The Sense, which is basically the Versa plus continuous EDA scanning to better alert you to stress patterns in real time for $50 more, and now the Pixel Watch 3, which is arguably a more advanced smartwatch and fitness tracker but only compatible with Android and $150 more than the Versa 4 (more on that one in a sec).
Still, the Versa 4 delivers on everyday usability: You'll get four to six days of battery life, a bright screen, and access to Fitbit's app experience (though a Premium monthly membership is required to get the most out of its offerings). If you want the sleekness and convenience of a smartwatch with most of the usable health and fitness features, all at a mid-range price, the Versa 4 is for you.
Honorable mention for Android users
The latest Google Pixel Watch offers robust fitness tracking benefits like Fitbit Morning Brief, advanced running features, and target cardio load. The bezel is still quite thick, but given most apps run on a black background, it's really not that noticeable, and the rounded glass design makes it one of the best-looking smartwatches money can buy.
Though not technically a Fitbit-branded device, the Google Pixel Watch 3 is now powered by Fitbit's technology, and it's such a good wearable that it's worth a mention in this guide. For Android users who want both smart features and Fitbit's health data, the Pixel Watch 3 is worth the price tag.
It includes advanced metrics like cardio load, workout fatigue, loss-of-pulse alerts, and a helpful "morning brief" that summarizes your sleep, weather, and calendar at a glance. The onboard microphone and speaker let you take calls, set reminders, and respond to texts, and the built-in workout builder (via the Fitbit app) is a standout tool for training.
You'll get better app integration and smart features than any Fitbit device, even the Versa. But the tradeoff is battery life — you'll need to charge it every 24 to 36 hours. It's also Android-only. Still, if you're someone who wants your health tracking built into a stylish timepiece, the Pixel Watch 3 is worth the extra spend.
How we chose the best Fitbits
As a health and fitness writer for more than a decade, I've worn a number of Fitbits in various generations while training for half-marathons, sweating in HIIT classes, and commuting to and from office jobs. While I haven't tested every model on this list, I am intimately familiar with Fitbit's technology and ecosystem and have researched its current product offerings extensively. When considering which is the best Fitbit for different types of people, I prioritized:
- Sensor quality and accuracy (heart rate, GPS, SpO₂, ECG, EDA)
- Battery life during real-world use
- Design, comfort, and durability for everyday and sleepwear
- Companion app quality for interpreting health data
- Platform compatibility across Android and iOS
I also considered which models give you the most features without requiring Fitbit Premium — though many models unlock deeper insights with a subscription.
FAQs
Are Fitbits worth it?
Fitbit wearables are backed with reliable heart rate technology, well-designed to be compact but readable, and generally very well-priced compared to other fitness trackers. What's more, the free Fitbit companion app offers a lot of value to people looking for guidance on improving their workouts, sleep, and stress levels, though you'll get more value with the Premium subscription.
There are other brands with better battery life, better GPS tracking, and potentially more robust smartwatch features, but if you want a reliable health and fitness tracker without spending a fortune, Fitbits are definitely worth it. For other top picks, check out our guides to the best Android smartwatches and best fitness trackers.
What is Fitbit Premium?
Fitbit Premium is the brand's monthly membership option. You can access the Fitbit app for free to see basic data like your steps, sleep score, period tracking, activity tracking, and the Daily Readiness Score. But for $10/month, Fitbit Premium offers access to more in-depth health and fitness features like nutrition insights, advanced sleep tracking (e.g., insights into your sleep stages), and access to the workout library and mindfulness library to reduce stress. It also offers guided meditations, exclusive video workouts, in-depth goal setting, various unique challenges, and other health insights such as blood oxygen level readings, heart rate variability, and breathing rate.
You don't need a Fitbit Premium subscription to use a Fitbit, but it does help elevate the base experience on any wearable in its lineup.
Is a Fitbit better than an Apple Watch?
The best Apple Watch models are undoubtedly more powerful and full-featured than Fitbits, but if you don't need access to a suite of apps, then a Fitbit will suffice. Both options offer deep tracking capability for activities like running, cycling, and lifting weights, and each comes standard with a user-friendly interface.
Though the Apple Watch now offers a deep well of fitness and activity tracking capability, it still leans more heavily toward being a smartwatch (similar to Fitbit's Versa line, though arguably better). So, if you're after basic fitness tracking without the frills, something like Fitbit's Charge 6 would be more your speed.
Will a Fitbit work with an iPhone or Apple Health?
Fitbits are compatible with any iPhone running iOS 16.4 or later, which the Fitbit app requires.
While a Fitbit can't directly sync to the Apple Health app, it is possible to use third-party apps like Strava as a go-between to transfer data indirectly from a Fitbit to the Apple Health app.
What's the battery life like on a Fitbit?
The most current Fitbit models offer anywhere from four to 10 days of battery life, with the average being around 6 days. In our experience, the Sense 2 lasts an average of six days on one charge, while the Inspire 3 lasts up to 10 days, for instance.
While the best Garmin watches generally have a longer battery life, most Fitbits last long enough that you won't have to worry about charging them every night.
How accurate are Fitbits for tracking steps, heart rate, and sleep?
Fitbits are very accurate for tracking steps, heart rate, and sleep quality. Because it's one of the original tracking brands, Fitbit has been refining its technology for nearly 20 years. While it is outperformed by Garmin in on-wrist GPS tracking capabilities (e.g., the exact mileage of your morning run), pretty much every fitness tracker is equally reliable in step count and heart rate these days.
Which Fitbit is best for beginners
The best Fitbit for beginners is the Inspire 3. It offers all the basics you'll want to kick-start your health journey — step count, sleep quality, automatic workout detection — without any of the superfluous data to overcomplicate things, and all for $100 or less. If you pay for a Fitbit Premium membership, you'll also score coaching on how to improve your workouts or stress levels.
