When it comes to wearable fitness trackers, few brands have the same deal of clout as Fitbit. The California based company was among the first to market, with the original Fitbit hitting shelves in 2009. Since then, the company’s put out a wide range of devices, and we’ve tested them all.
Of course, Fitbit’s devices, from the original Fitbit Classic, all the way up to the recent Fitbit Versa 4, have taken on all sorts of shapes, features and aesthetics. As a result, while one Fitbit might be great for one person’s workout routine, there might be a more suitable option for someone else.
For example, the Fitbit Charge 5 is a solid choice if you’re after an inexpensive fitness tracker that can get the job done, especially on a run. If you’re after a fitness tracker/smartwatch hybrid however, then the Fitbit Versa 3 or the Fitbit Sense 2 will better suit the bill.

How we test
We use every Fitbit we review as our primary wearable for at least a week – or longer, if the battery life lasts beyond that point or we need more time to trial its features.
During that time we will test it on a variety of different activities. These will range from basic step tracking, to how well it tracks runs, swims, cycling and more.
For distance tracking, we assess how accurately the device records runs on tracks we know the length of. We also evaluate the level of battery life lost per hour using features such as built-in or connected GPS. To check heart rate accuracy, we compare the results from the wearable to a dedicated HRM strap.
Next we combine the data recorded with our general experience of using the wearable day-to-day, revealing whether the device proved comfortable to wear, alongside any issues we may have encountered with unexpected bugs over the review period.
We then evaluate key metrics including app support, usability and battery life.
Fitbit Charge 5
The Best Fitbit fitness tracker
Pros
- Vibrant colour display
- Comfortable strap
- Added ECG sensor
Cons
- Screen responsiveness a little temperamental
- ECG and Daily Readiness Scores not available (yet)
- GPS accuracy not great
The Fitbit Charge 5 is a great visual improvement over its predecessor thanks to its bright and detailed AMOLED screen, which adds a great deal of life and vibrancy to this handy wearable. It’s also an ergonomic success too, with a very comfortable and secure strap and an aluminium casing which is more appealing than the resin of the previous generation. This unit is waterproof up to 50 metres, so you can safely take it for a dip as well.
The tracking is particularly good when it comes to counting your steps or monitoring your sleep, which is accurate and gives you the data you need to keep a better eye on your health. The heart-rate sensor is also very accurate, but the on-board GPS was a little more wobbly and took a long time to lock on to your location. The generous battery life is also likely to give you a week’s worth of use before you need to charge it back up again.

Fitbit Sense 2
The best Fitbit smartwatch
Pros
- Physical button is back
- Reliable resting heartrate data
- Strong sleep tracking features
Cons
- Sluggish software
- Missing smartwatch features
- Some new features not available yet
The Fitbit Sense 2 is an all-round smartwatch that has a bit more functionality than a basic fitness tracker. It’s got a thin and light build, an appealing colourful AMOLED touchscreen display, and a physical button on the side.
However, it has to be said that the smartwatch experience here isn’t as well-executed as other brands’ offerings, because the support for certain key apps is lacking (at least at launch, when even the likes of Google Maps and Google Wallet were unsupported), and the performance is a bit laggy too due to an underpowered chipset.
However, the fitness and health features – including in-built GPS, ECG and skin temperature sensors, and blood oxygen tracking – all combine to help give you a strong picture of your overall wellbeing. The watch makes it easy to keep tabs on your sleep and on your stress levels, but if you want to get a deeper look into your athletic training then this one isn’t the strongest.
We found that the Sense 2 could hold up for around six days before needing a charge, though that’s reduced to 3 days if you keep the watch in always-on mode.

Fitbit Versa 3
The best affordable Fitbit smartwatch
Pros
- Feature-packed for the price
- GPS is finally here
- Six-day battery with intensive use
Cons
- Fitbit’s apps and app store still need work
- The step count is just too eager
- Still no support for offline Spotify
- Fitbit Premium is essential for getting your money’s worth
The Fitbit Versa 4 is the latest device in Fitbit’s Vera line-up, but we actually preferred its predecessor and that’s the one we’d choose out of the two. Why? Well because the feature list is more or less the same as this one, and actually some have been lost; the newer watch doesn’t have Wi-Fi connectivity or a music player, both of which are present here.
For the price this watch delivers plenty of features and is therefore a tempting proposition, though features such as the GPS and the heart-rate tracking are not highly accurate and even the step counter can be a bit over-generous.
However, if you’d like a Fitbit with some smarter features, and want to save a bit of money, then this is a decent option.

Fitbit Luxe
The best-looking Fitbit
Pros
- Decent-quality AMOLED screen
- Good for resting heart rate monitoring
- Nice straps available
- Works well for sleep tracking
Cons
- Notifications feel cramped
- Connected GPS support isn’t always reliable
- Features hidden behind Premium subscription
- No payment support
Slim and attractive, the Fitbit Luxe is light to wear and has a selection of appealing metallic cases, and equally appealing watch bands, that make it a tab more fashionable to wear compared to standard fitness tracker and smartwatches. The screen is also sharp and bright, and it’s purely touchscreen without any input buttons.
In terms of health monitoring, this watch will gives reliable continuous heart rate sensing and comfortable and accurate sleep tracking too. There aren’t tonnes of additional exercise-tracking options here, but this is a handy little tool for keeping an eye on your day-to-day health and wellness.
You’ll get around five days’ battery life from this wearable before you need to charge it back up, which isn’t brilliant, and it’s fairly slow at recharging too as it takes two hours to go from 0-100%.
This tracker isn’t right for you if you want intensive exercise logging or a host of smart features on your wrist, but it’s still a handsome and helpful little accessory.

Google Pixel Watch
The best Fitbit that’s not a Fitbit
Pros
- Cleaner feeling version of Wear OS
- Crisp display
- Fitbit added into the mix
Cons
- Battery drain
- Awkward to change straps
- Sub-par sports tracking
The Google Pixel Watch might not be branded as a Fitbit on the box, but to all intents and purposes that’s exactly what it is; Fitbit fitness tracking is well-integrated on this watch, so if that’s a major selling point for you then you’ll be relieved to see the familiar interfaces on this product too.
Google’s first-ever own-brand smartwatch is sleek and elegant, and it’s also remarkably small too with just a 41mm casing. There’s a crown and a side button to complement the touchscreen, which is a rich AMOLED panel that’s bright and brilliant despite the bezel running around the edge.
There’s very little lag on this watch when you’re zipping around the interface, though there are occasionally long loading times, and the Wear OS software feels particularly clean and pure. Part of the appeal lies in the close collaboration with Fitbit, which is responsible for step counts, sleep tracking, and exercise tracking. There are handy ECG and blood oxygen sensors here too.
We found that health metrics such as heart rate and sleep were reliable, but it was a different story when it came to exercise tracking, as the on-board GPS was fairly inaccurate, and the swimming tracking was so dreadful as to be useless. Another bad miss was the battery life, which is far shorter than other Fitbits; it will get you through the day, as long as you don’t use the GPS too much, but that’s it.

Fitbit Inspire 2
Best Fitbit for beginners
Pros
- Excellent battery life
- Comfortable fit
- Slick Fitbit app
Cons
- No GPS
- No Fitbit Pay
- Pokey display
The Fitbit Inspire 2 is our choice if you’re new to the world of fitness trackers and would like to be eased in gently. There’s no on-board GPS or NFC payment option here, as this device isn’t about premium features, but it does fit very comfortably on your wrist, offers great battery life, and has that same slick and useful Fitbit companion app.
If a daily step count, good sleep tracking, and a heart rate monitor is all you need, then this little watch will deliver it subtlely but reliably, and will help you get used to the idea of wearing a fitness tracker without demanding too much attention. However, if you’re already a keen fitness fanatic then you’ve graduated beyond the need for a watch like this.
