There's such a selection of Fitbit smartwatches and fitness bands, choosing the right device feels mindboggling. That's why we've set up this feature, to try and compare Fitbit models.

New Fitbit devices like the Fitbit Sense have reached another level of features and health tracking, so now it's a choice about how much data you want to collect.

Fitbit devices range between simple steps and sleep tracking at one end (Fitbit Inspire), to full tracking of your heart vitals, sleep stages and even body temperature stress levels at the other (Fitbit Sense).

You'll also need to weigh up whether you want a fitness tracker or smartwatch form factor.

There's no wrong or right answer here.

Read on for our guidance based on years of reviews and testing.

Fitbit watches vs bands

But if you already have a watch that you love to wear, you might want to choose a Fitbit band so you're not wearing two wrist watches.

Some people also just don't get on well with watches, and prefer something slimmer. And the Fitbit Inspire can be clipped on, so there's no need to wear something on the wrist at all.

Then there's features. A lot people think about a Fitbit in terms of 10,000 steps a day - but now they're all about heart rate tracking and analysis, resting heart rate and sleep monitoring too. But if you're an active person, or really hungry for in-depth data – you'll be looking at specific trackers in the range. Read on for our comparison and reviews.

Update: We updated this article in October 2020 with details of brand new Fitbit devices, and will add our reviews once those have been reviewed next month.

Fitbit Sense

Fitbit Sense - the best fitbit

The best health tracking Fitbit


Fitbit Sense features: Heart rate | ECG | Stress detection | Temperature | VO2 Max | GPS | SpO2 sensor | Steps | Sleep tracking | Guided Breathing | Workout modes


If you're choosing a Fitbit, but looking for a little more detail than just your daily step count, the Fitbit Sense is the device for you.

It's a fully fledged health watch, with every bell and whistle you can imagine. In fact, it's provides more data about your wellbeing than any rival on the market.

Stress tracking, mindfulness via an electrodermal activity sensor, ECG, temperature monitoring all join blood oxygen, 24/7 heart rate, top sleep tracking and, of course, your step count.

There's also GPS, loads of workout modes, and it will kick your data out to platforms like Strava if you hook them up.

Fitbit has put an added focus on its Fitbit Premium, so subscribers to the $79.99 a year service will get even more data.

Premium reveals a whole dashboard of new raw data called Health Metrics across all devices – but Sense leverages the most. You get temperature and resting heart rate, breathing rate, oxygen saturation, and heart rate variability all shown in one screen.

If there's a downside it's that there are a lot of graphs, but not a lot of information about what's happening under the hood, so we'd advise getting yourself clued up on the key metrics.

At the moment Fitbit Sense has some annoyances - and the on-watch experience is a little laggy, and the wrist-raise is too slow. Hopefully these get fixed up, because you do get around six days of battery life, a seriously rapid fast charge. And Fitbit Pay is on board if your bank supports it.

Fitbit Charge 4

Fitbit Charge 4 on wrist from our review

The best fitness tracker


Fitbit Charge 4 features: Heart rate | VO2 Max | GPS | SmartTrack | SpO2 sensor | Steps | Sleep tracking | Guided Breathing | Workout modes


If you're looking for a Fitbit then there's a new sheriff in town. The Fitbit Charge 4 isn't just the most powerful Fitbit tracker we've seen to date, but one of the most powerful fitness trackers full stop.

Most of the race for health innovation is now played on on smartwatches, so the full gamut of features in wrist-band form is now pretty unique. GPS is the big new addition, offering accurate tracking of runs and cycles from the wrist, and the Charge 4 also has an SpO2 sensor for blood oxygen, will monitor VO2 Max, resting heart rate, and boasts Fitbit's brilliant sleep tracking smarts as well.

It's swim-proof with 5ATM water resistance, and will track and tag data from 20 sports, from HIIT and yoga to general workouts (although just basic calorie, HR and duration data).

The Fitbit Charge 4 certainly sets out its stall as a great device for those who like to workout, do HIIT, living room workouts, gym classes and the odd run. If you're a 10,000 steps a day person it's overkill, and committed runners will crave more detail on progression. But it's a fine update to the Charge 3, although we do wish Fitbit has worked on the screen, which looks pretty dated these days.

With the inclusion of the SpO2 sensor, the Charge 4 is also one of the best Fitbit devices for sleep tracking. It has Sleep Stages, Sleep Insights, Sleep Score and Estimated Oxygen Variability - all metrics that far outweigh the rest of the competition.

The Charge 4 isn't just one of the best Fitbit trackers you can buy, it's one of the best wearables you can buy.

Fitbit Versa 3

Fitbit Versa 3 - from our review

The best Fitbit smartwatch


Fitbit Versa 3 features: PurePulse 2.0 HR sensor | GPS | SpO2 sensor | Swim tracking | Sleep tracking | Fitbit Pay | Notifications | App Gallery | Alexa | Music storage | Women's health tracking


While the Fitbit Sense has stolen the show as the company's flagship smartwatch, the Versa 3 is here for those that don't want to pay big money for features like ECG and stress.

The Versa 3 is a solid update to the previous version, adding GPS for outside tracking of workouts.

It also gets the upgraded PurePulse 2.0 HR sensor, which should be more reliable but still struggles at very high intensity.

As a smartwatch and fitness tracker, the basics are the still same – with heart rate, steps, sleep tracking all done within the Fitbit app. The SpO2 sensor is now live, too, adding insights into Estimated Oxygen Variability, as well as Sleep Score, Sleep Stages and Sleep Insights.

And Fitbit Premium users will get breathing rate, heart rate variability, oxygen saturation and resting heart rate in the new Health Metrics dashboard.

You still get Alexa is chief among these, where a button press will summon Amazon’s voice assistant for alarm setting, timers, and quick check-ins on your goal progress – if you like that sort of thing.

Check out our full review of the excellent Fitbit Versa 3.

Fitbit Inspire 2

Fitbit Inspire 2

The best basic Fitbit fitness tracker


Fitbit Inspire series features: Step tracking | Waterproof | Swim tracking | Heart rate (Inspire HR) | Sleep tracking (Inspire HR) | Screen and notifications | SmartTrack | Interchangeable bands


The launch of the Fitbit Inspire 2 is a minor update to the Inspire HR, but a better screen and the new Active Zone Minutes feature make it a no-brainer at the same price.

The slimline, dainty activity bands are perfect for smaller wrists, yet they still manage to boast a relatively big touchscreen display. What's more, they're also waterproof, offering some basic swim tracking – making it more versatile that its predecessor, too.

It covers the usual fitness tracking bases, with the Inspire HR unlocking features like Sleep Stages, guided breathing and training with heart rate zones. You also get the goal-based exercise modes from the Charge 4 and SmartTrack tech to automatically recognise when you're working out.

There's notification support here, but that's as far as the smartwatch features go. There's no third-party app support, either, but you do get a decent handful of watch faces to choose from.

It's a feature-packed fitness tracker that, crucially, doesn't come at a great expense. This is now Fitbit's cheapest tracker range, whether you go for the Fitbit Inspire or the Inspire HR.

Combined with Fitbit's great companion app that also unlocks additional features, like women's health tracking, you're getting a great overall fitness tracker that won't break the bank.

Fitbit Versa Lite Edition

Fitbit Versa Lite edition

The best cheap Fitbit smartwatch


Fitbit Versa Lite features: Heart monitor | Waterproof | Swim tracking | Sleep tracking | Notifications | App store | Women's health tracking | ConnectedGPS


The original Versa was a massive success, so it came as no real surprise when Fitbit capitalized by releasing another variation of the model.

A great pick for those who want the core Versa experience for a little less outlay, the key differences between this and the newer Versa 2 are the boxier design and the strip-back of high-end features.

There's no on-board storage for music, there's no Fitbit Pay, there's no swim lap tracking and there's no altimeter. Everything else is still here, though, meaning it's swim-proof, runs Fitbit OS, has workout modes and a heart rate sensor and SpO2 sensor.

It's a near identical design to the Versa 1, though Fitbit has ditched the two side buttons, making it slightly more in line with the Versa 2.

On the software front, it's largely the same experience, although you do miss out on Fitbit Coach support to download workouts onto the watch. Updating the watch is done a little differently, too, with Wi-Fi missing in action, doing it in the background when you sync the device to the app.

Sports tracking performance is pretty much identical to the first Versa, too, while battery life will get you through four or five days.

If you can live without those extras and just want that core smartwatch experience, then the Versa Lite definitely fits the bill.

Fitbit Ace 2

Fitbit Ace 2

The best Fitbit for kids


Fitbit Ace 2 features: Step counting | Swim-proof design | Sleep tracking | Activity | Challenges


The Fitbit Ace 2 is aimed at kids aged six and up, with the latest generation featuring a modular design that utilizes a bumper to keep the display a little more protected as kids run around and play.

The Ace 2 still does the fitness tracking basics. There's steps and active minutes, and it can also log sleep duration and quality, telling you whether your child was restless, asleep or awake during the night.

There are new watch faces with animations that Fitbit hopes will keep kids motivated, too. And to make it a truly versatile tracker, it's swim-proof so your kids will be able to hit the pool with it.

On the privacy front, Fitbit says the Ace is 100% applicable to all child privacy laws, and, when you set up the Ace 2 for the first time, it'll make sure to walk you through its privacy policy.

Even better, your kids will get to grow up with the Ace. They'll be able to pop out the tracker for the bumper and put it into bands from the new Inspire fitness tracker and even upgrade the UI to something less cartoony.
