Incoming: New Fitbit devices
We’re working on our full testing of these devices and will update you as and when our verdicts are in
Google Pixel Watch
The newly announced Google Pixel Watch is a Fitbit in its own right, connects to the company’s app, and offers the full gamut of features.
The Google Pixel Watch runs Wear OS 3, rather than Fitbit OS, and boasts a 41mm circular case with a domed screen, which certainly catches the eye. As such, it offers the full selection of apps from the Google Play Store and Google Pay.
But the ace up its sleeve is access to Fitbit services. You can connect it to the Fitbit app, and get 24/7 heart rate data, Health Metrics Dashboard information, sleep tracking with stages data, and even Premium-only features, such as Daily Readiness.
Buyers also get six months of Fitbit Premium, and access to all the mindfulness content.
Fitbit Sense 2
Fitbit’s flagship health watch is back, and it’s gone all-in on stress. The EDA sensor, which reads stress responses via the palm, is now continuous. It’s called Body Response Sensor and can offer a much more detailed look at stressful feelings, and it will prompt you for manual feedback on how you feel.
Elsewhere, the Fitbit Sense 2 is lighter and thinner than its predecessor and still packs in the ECG sensor found on the original Sense.
Again, the Sense 2 is designed for those who want to keep a close eye on heart rate rhythm data and stress â if those things don’t interest you then the Fitbit Versa 4 will be of greater interest.
Fitbit Versa 4
The Versa 4 is the revamped version of Fitbit’s smartwatch, and with 6 days of battery life and a sub $250/Â£200 price tag, it offers a strong alternative to the Pixel Watch.
Fitbit added a tactile button to the case, which makes the watch easier to use, especially with sweaty hands.
And it features a revamped Fitbit OS, with Google Wallet and Google Maps â and the latter will offer turn-by-turn directions.
It doesn’t feature the same access to the Wear OS app collection as the new Pixel Watch, but it offers all the same tracking with battery life that the likes of Apple, Google and Samsung can only dream of.
Fitbit Inspire 3
The Fitbit Inspire 3 gets a full-color display for the first time â and the company’s entry-level tracker is a significant upgrade to the Inspire 2 at the same price.
What’s more, SpO2 also makes its debut on the Inspire 3 for the first time, which is now ubiquitous across the whole range.
Thereâs 10-day battery life, which is impressive given the big boost in screen tech and the demands of a SpO2 sensor.
And you get access to all the features that make Fitbit a great platform, from Active Zone Minutes, top sleep tracking, and the new sleep profiles â the Inspire 3 is extraordinarily complete.

The best devices that have passed through our reviews
Fitbit Charge 5
Price when reviewed: $179.95/Â£169.99
The most advanced Fitbit tracker
Fitbit Charge 5 features: Heart rate | ECG | Stress tracking | Temperature | VO2 Max | GPS | SpO2 sensor | Steps | Sleep tracking | Guided Breathing | Workout modes | Women’s health tracking
The Charge 5 is Fitbit’s flagship tracker and follows the Fitbit Luxe by introducing a stainless steel case and AMOLED display, which makes it far more wearable and pleasing on the wrist.
The Charge 5 screen size is 11% bigger than the Charge 4, and the device itself is 1mm taller but over 1mm thinner.
But it’s packed with sensors that make the Charge 5 a mini-smartwatch in its own right.
It brings ECG and the EDA stress sensor from the Fitbit Sense, the first time these have been seen on a fitness tracker form factor. That joins GPS alongside the standard set of advanced sleep, stress score, Active Zones Minutes, and all-day heart rate tracking.
There’s skin temperature and the new Daily Readiness score, which assesses how well-rested you are before recommending workouts. Both of these are cleverly calculated from personal baselines, tailored to your physiological profile.
We’ve now had time to review the device â and to recommend it comes with caveats. If you want the chunkier, more male-friendly form factor, or the ECG then it’s a no-brainer, it brings Fitbit’s platform to your wrist in a sleek and wearable package.
But the GPS accuracy is problematic, which undermines a huge part of its USP. And if you’re not interested in ECG, then is it worth paying more for?
For a lot of people, the Fitbit Luxe is a smarter buy. It’s a question of personal design preference and interest in those advanced features.

The best health watch
Fitbit Sense features: Heart rate | ECG | Stress tracking | Temperature | VO2 Max | GPS | SpO2 sensor | Steps | Sleep tracking | Guided Breathing | Workout modes | Women’s health tracking
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. It provides more data about your well-being than any rival on the market.
Stress tracking, mindfulness via an electrodermal activity sensor, ECG, and temperature monitoring all join blood oxygen, 24/7 heart rate, top sleep tracking, and, of course, your step count.
There’s also GPS, and 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 â but Sense leverages the most. You get the temperature and resting heart rate, breathing rate, oxygen saturation, and heart rate variability all shown on 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.

Best Fitbit for women
Fitbit Luxe features: Heart rate | VO2 Max | SpO2 sensor | Step tracking | Sleep tracking | Guided Breathing | Workout modes | Skin temperature | Women’s health tracking
There’s a new Fitbit in town and it’s bringing some much-needed style to the party. The Fitbit Luxe introduces a stainless steel case and a color AMOLED display, both of which are a huge visual step up from the Charge and Inspire.
It’s something you might want to wear. And while the look and feel are Luxe, the price tag is not. It retails for $149.99/Â£129.99 â which is the same as a standard Charge 4.
It comes in white, black, and orchid (pink) options and there’s a special edition with a gold link bracelet. It’s not exclusively for women, but quite obviously marketed that way.
Compare: Charge 5 vs Luxe
In terms of features, there’s nothing exclusive to Luxe, but plenty of top features filter down the Fitbit range. It’s not as advanced as the Charge 4 (there’s no GPS, for example) but trumps the Inspire range with its SpO2 sensor for blood oxygen.
There’s also a new drive towards mindfulness, and it will keep tabs on stress using a daily stress score. That feature is rolling out across Fitbit devices. That’s on top of sleep, heart rate, and steps â everything you expect from Fitbit.
In short, the Luxe puts the best parts of the Fitbit experience in a nicer, sleeker, and more stylish package. What’s not to like about that?

Fitbit Versa 3

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 â with heart rate, steps, and 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.
Alexa is chief among these, where a button press will summon Amazonâs voice assistant for alarm setting, timers, and quick check-ins on your goal progress â if you like that sort of thing.
Check out our full review of the excellent Fitbit Versa 3.
Fitbit Inspire 2
Price when reviewed: $99.95/Â£89.99
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 slimline, dainty activity bands are perfect for smaller wrists, yet they still manage to boast a relatively big touchscreen display.
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 recognize 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.
Check out our comprehensive Fitbit Inspire 2 review.

The best Fitbit for kids
Fitbit Ace 3 features: Step counting | Swim-proof design | Sleep tracking | Activity | Challenges
The Fitbit Ace 3 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 3 puts move reminders at its core, reminding kids to get those 250 steps per minute on their way to 60 minutes of active time per day.
It’s still a monochrome display, so no color options here. And the main features are still step tracking, sports monitoring, and sleep insights. Thereâs no heart rate monitor, but it does boast swim-proof 5ATM water resistance.
There are also bedtime reminders and silent alarms to help parents get a settled sleep schedule and there are also timers and race the stopwatch features built into the watch.
The larger tracker also means a boost in battery life and it will now last 8 days between charging, up from 6 days on the previous generation.
