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 August 2020 with details of brand new Fitbit devices, and will add our reviews once those have been reviewed next month.

Incoming Fitbit devices

While our best Fitbit round up is devices that have been through our tough testing process, we can't ignore the new Fitbit devices launched in August 2020.

Fitbit Sense

Best Fitbit 2020: choose your perfect watch or band from our reviews

The new Fitbit Sense is the company's new health watch, and is easily the most advanced Fitbit smartwatch to date.

The Fitbit Sense adds ECG for the first time on a Fitbit, with afib detection and high/low heart rate alerts.
It adds temperature tracking alongside breathing tracking, heart rate variability, resting HR and blood oxygen, to warn against infections such as Covid-19.
And stress is a big target, and it packs in an electrodermal activity sensor (EDA) to produce a daily stress score.

Fitbit Versa 3

The Fitbit Versa 3 also adds GPS (at last) with a larger AMOLED display than its predecessor.

The Versa 3 also gets the same PurePulse 2.0 tech from the Fitbit Sense, which promises to be more accurate than previous devices.

And the smartwatch now has a choice of voice assistant, with both Alexa and Google Assistant on board.

Fitbit Inspire 2

And finally the Inspire 2 fitness tracker adds a better screen and the new Active Zone Minutes metric to be a better all-round performer at the same price as its processor.

We'll be getting in each of the new Fitbits for review over the coming weeks before the end of September release date.

1. Fitbit Charge 4

Fitbit Charge 4

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.

2. Fitbit Versa 2

Best Fitbit 2019: Features, price and style compared

The best Fitbit smartwatch


Fitbit Versa 2 features: Heart rate monitoring | SpO2 sensor | Swim tracking | Sleep tracking | Fitbit Pay | Notifications | App Gallery | Alexa | Music storage | Women's health tracking | ConnectedGPS


While the company has launched the Fitbit Versa 3, expect to see big deals on the Versa 2 which still stacks up well if you can live without GPS.

One of the best compliments you can pay the Versa 2 is that it doesn't mess with the winning formula too much, simply adding nifty new features and refining the design.

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. There’s no speaker - so all responses will be text-based - but it's a great way of controlling your smart home and tapping into the smart assistant on-the-go.

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.

There’s still no built-in GPS, but it will take the connection from a paired smartphone if you're out exercising. Or, you can leave your phone at home and let the watch use its accelerometer to estimate your distance.

Overall, the Versa 2 is a minor upgrade but adds a bunch of new features at a really competitive price. It's a good buy if you’re looking to jump into Fitbit’s superb fitness and health tracking.

3. Fitbit Ionic (discontinued)

Best Fitbit 2020: which fitness tracker or smartwatch is right for you?

Best Fitbit for runners


Fitbit Ionic features: Built-in GPS | Waterproof | Swim tracking | Heart rate | SmartTrack | Sleep tracking | Fitbit Pay | Notification support | Cycle tracking


The arrival of the Versa 3 with GPS means the Ionic has been dropped from the company's website, signalling the end for Fitbit's dedicated sports watch. But it will likely get some tasty deals this Black Friday, and it may suit some looking for cut-price Fitbit for runners.

With a sportier design and GPS, this makes it more of a Garmin rival, bringing all the usual frivolities in the exercise tracking department. Expect your steps and calories to be counted, alongside the option to make use of the altimeter, accelerometer, compass, GPS and heart rate monitor for more rigorous activity.

The company's SmartTrack tech will automatically recognise a score of different exercises, but runners, cyclists, swimmers and treadmill runners will also have dedicated modes within the watch. And for those looking for a more structured workout, the Coach app is available to provide plans of varying difficulties and durations.

It's not just activity Fitbit is helping you with, though, as its sleep technology and Fitbit Pay also work in the same way as the Versa 2 and Charge 3.

The design may be a sticking point for some, but this is a sporty smartwatch that represents the best of what the company has to offer. That includes the Fitbit app store, which Versa series owners can also peruse, and an impressive four-day battery life.

4. Fitbit Inspire HR

Best Fitbit 2020: which fitness tracker or smartwatch is right for you?

The best cheap 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 means that anyone considering this version should keep their wallet fastened until the end of September. However, as that's a minor upgrade if you see any Inspire HR deals it could be worth investing.

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 3 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.

Both now sit below the £100 price mark, with the regular Inspire closer to £50 and is the cheapest you can officially buy.

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.

5. Fitbit Versa Lite Edition

Best Fitbit 2019: All our new Fitbit reviews for you to compare

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.

6. Fitbit Ace 2

Best Fitbit 2020: which fitness tracker or smartwatch is right for you?

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.
