We’ve tested and ranked the best Fitbits available today, so you can be confident you’re choosing the right one. We’ve put all these fitness trackers through their paces in real world conditions, during workouts and everyday life, so you know exactly how each device works and feels to use.
If you want to find out more about any of the Fitbit wearables we’ve included, make sure to click through to our reviews for an in-depth look at each of them.
We’ll soon be reviewing the new Fitbit Luxe, which is Fitbit’s most fashion-forward device so far, so check back soon to see whether it earns a place in this guide.
If you can wait until Amazon Prime Day 2021, we’re expecting to see some significant savings on Fitbits, many of which are likely to be matched by other retailers. Amazon has a track record of knocking substantial amounts of cash off even newly released fitness trackers for Prime Day, so the Fitbit Inspire 2 is likely in line for a price cut. Also watch out for deals on the Sense and Versa 3, which are likely to be cheaper than any other time of year.
The Fitbit Versa 3 is our number one pick for the best Fitbit you can buy today. It looks stunning, with an aluminum case, and bright, crisp screen, and is packed with useful tools for both everyday wear and activity tracking.
You can receive smartphone notifications (which are customizable), make contactless payment via Fitbit Pay, control your music, monitor your blood oxygen saturation (SpO2), be guided through calming breathing exercises, and track your sleep. The Fitbit Versa 3 can track 30 different types of exercise (indoors and out), and the resulting GPS data can be synced automatically to services like Strava, as well as being displayed in the Fitbit app.
Voice commands are supported too, with Amazon Alexa and Google Assistant integration, and you can download additional third-party apps through the Fitbit App Gallery,
The Fitbit Versa 3 will need charging more frequently than some other watches in this list, but if you don’t mind clipping on its charger every six days or so, it’s easy to recommend.

The Fitbit Charge 4 neatly bridges the gap between activity bands and fully fledged fitness trackers. It’s simple and discreet enough for everyday wear, but has all the features you need for tracking workouts too.
The on-board GPS makes it a viable option for runners who’d prefer to leave their phone at home. There’s also Fitbit Pay for contactless payments, and if you are carrying your phone, you can use the Charge 4 to control your Spotify playlist.
When paired with the Fitbit App, the Charge 4 will also track Active Zone Minutes – a measure of exercise intensity recommended by various health organizations. These are based on heart rate training zones, but simplified so they’re easy to understand, and you’ll be set specific goals depending on your age and general fitness, as measured by the device.
The Fitbit Charge 4 costs the same as the Charge 3 did at launch, which is an impressive feat considering the upgrades under the hood. There’s still no color screen, but this is a superb fitness tracker that has the features that really count.

The Fitbit Sense is the company’s most advanced fitness tracker to date, with on-board GPS, an ECG sensor to detect signs of atrial fibrillation, and a new stress monitor that uses changes in the conductivity of your skin to estimate how much pressure you’re under. This data syncs with the Fitbit app, where you can also record your mood and any factors that might have influenced how you’re feeling so you can look for patterns.
The Sense is an excellent sports watch as well, with a huge range of activity tracking options. You can configure your favorite workouts so they appear as quick shortcuts when you press the touch-sensitive button on the left-hand side of the Sense’s case, and there’s on-board GPS to map runs and rides (which can be synced to Strava automatically).
It’s a great looking watch too, with an almost identical design to the Fitbit Versa 3, but features a new Infinity Band strap that makes it extremely comfortable to wear, even at night.
Our main complaint is that the step tracking can be a little inconsistent, recording steps even though you’ve told the device you’re taking part in a cycling activity. Otherwise it’s an excellent device that’s easy to recommend.

The Fitbit Inspire 2 is small, slim, and a great tool if you’re looking for a fitness tracker that will gently nudge you towards making healthier lifestyle choices.
It’s extremely easy to use, with a small but clear touchscreen operated using taps and swipes, and a single side button. It will automatically track your heart rate and activity levels all day (and alert you when you achieve your step goal), and offers over 20 workout modes, including several that start tracking automatically thanks to the device’s in-built accelerometer.
There’s sleep tracking as well, and all your data will be neatly collated in the Fitbit app, where you can monitor trends over time and set targets.
Perhaps best of all, it can keep running for well over a week on a single charge, so you don’t need to worry about plugging it in every night. A great choice for anyone who’s just starting to get more active and wants a little encouragement.

The Fitbit Ace 3 is a fitness tracker designed specifically for kids. Although it does track steps, it’s not just a simple pedometer; the Fitbit Ace 3 also tracks other activities (such as trampolining and school sports), with achievements to encourage kids to be more active.
There’s no all-day heart rate monitor (which makes sense, since kids’ resting heart rate changes as they grow), and no calorie counting or GPS. However, if your child has their own phone, they can use it to receive app notifications.
The Ace 3 is designed for ages six to 13, which is a broad range, but unlike some alternative devices it’s not adorned with cartoon characters, which means it’s not embarrassing for older kids to wear. In our tests, we were also pleased to find its band didn’t irritate sensitive skin, which is an important factor when kids are going to be wearing it all day.

The Fitbit Inspire HR has been superseded by the recently announced FItbit Inspire 2, but it’s still an excellent basic fitness tracker that will serve you well if your needs are relatively straightforward.
It’s reasonably affordable yet comes with a lot of features including – obviously – heart rate tracking, as well as activity tracking, sleep monitoring, and guided breathing exercises. There’s also connected GPS, but no onboard GPS.
Other highlights of the Fitbit Inspire HR include great battery life of around five days in our tests, and a sleek, surprisingly premium design, making this one of the best-looking Fitbits you can buy. It’s also waterproof, though doesn’t come with any real swim-tracking skills.
Basically, if you don’t need to track your activity in the pool, don’t mind taking your phone with you on runs and don’t need something that’s more of a smartwatch, this is the best Fitbit option – and if you do need those other features you’ll have to pay more.

The Fitbit Versa 2 has now been superseded by the Versa 3, but it’s arguably still one of the most versatile devices that the company offers.
You can get notifications through to your wrist, use Amazon Alexa functionality, and access a variety of third-party apps directly on your wrist. That’s all on top of the great fitness features like a heart rate tracker and exercise monitoring that you’ll get from most Fitbit products.
Plus, the Fitbit Versa 2 has better battery life than most smartwatches, lasting around five days on a single charge, and with its lightweight design it won’t weigh you down while exercising.
There’s no built-in GPS here though, so you’ll have to take your phone on any runs you go on if you’re after a device to track your location.
Fitbit recently recently announced a new watch in the Versa lineup, the Fitbit Versa 3, which will add Google Assistant support and on-board GPS to the Versa 2’s feature set. We look forward to testing it, and will update this guide once we’ve put it through its paces.

Although it’s now a few years old, the Fitbit Ionic has stood the test of time, and can tackle running, weight lifting, swimming and much, much more.
Dedicated workout programs and Fitbit Pay are among the other highlights of the Ionic, but it doesn’t perform as well as say the Apple Watch 6 if you’re looking for a full blown smartwatch experience.
It’s not cheap either and the Fitbit Ionic is also low in our list of the best Fitbit products because it’s just very expensive for what it can offer you. However, if you’re an outdoor runner the Ionic is your best bet. Not only is it durable, but it has built-in GPS, meaning you can leave your phone at home.

The Fitbit Inspire is basically a cheaper alternative to the Fitbit Inspire HR for anyone who doesn’t need a heart rate monitor. It’s now been replaced by the Fitbit Inspire 2, which we’re currently in the process of reviewing.
That somewhat limits its skills, but there’s still a lot to like here, including an attractive, petite design, activity tracking, sleep tracking and up to five days of life.
Sadly there’s no GPS here – not even the connected kind – so this is more for people who want a very basic activity tracker than a real workout companion, but it’s priced accordingly and what it does it does well.
