I tested the latest Fitbit trackers to see if they are still worth buying in 2025

The latest to be released was the Fitbit Charge 6 tracker in 2023. The rest of the current line up is even older, with the Fitbit Inspire 3, Versa 4 and Sense 2 coming out in 2022. All four are still available to buy from , Fitbit's owner, and other major UK retailers.

Given Fitbit is still a household name, it's a little odd we haven't seen any new models in 2024 or 2025 so far. Google acquired the famous fitness brand in 2021 and has not only taken some features away, but also .

Does that mean we will see another Fitbit activity tracker, though? Only time will tell.

Google has instead spent the last few years redesigning the Fitbit app for use with existing Fitbits and also the line up, which requires the Fitbit app to track fitness metrics.

But if you are considering buying a Fitbit in 2025, it's right that you ask if it's worth it. Though you don't always need to buy the newest phone, tablet or indeed fitness tracker, I decided to strap on the latest Fitbits to see how they are performing today, and whether I think they are worth your time and money.

All Fitbits are compatible with modern and phones, with all features available on both platforms.

Google loaned me the Fitbit Inspire 3 and Fitbit Versa 4 to test out, and I still had to hand the sample I used to review the Fitbit Charge 6. Unfortunately I was not able to test the Fitbit Sense 2, but when I worked at another publication, and wore it for a few months after that, so I have plenty of experience with it.

I've split this article into sections that look at each Fitbit separately with a definitive verdict on if you should buy each or not in 2025.

• Released: September 2022
• RRP: £84.99
• Good: Battery life, comfortable 24/7 wear
• Bad: Tracking runs, small screen

The Inspire line hosts Fitbit's entry-level trackers, and the Inspire 3 is head and shoulders better than its predecessors thanks to a colour screen, extensive tracking smarts including blood oxygen and irregular heart rate notifications. It's all packed into a dinky tracker that's light and comfortable to wear.

I eked nearly ten days of battery out of it too, which makes it the longest lasting Fitbit by far. When I set it up there was a software update waiting for me, which was released this year, so Google is still keeping the tracker up to date.

Compared to other Fitbits, the Inspire 3 lacks built-in GPS. This means it can't track routes of runs, walks or cycles on its own, but it does have connected GPS, which means it can track them if you bring your phone with you.

The tracker also doesn't have Google Maps or Google Wallet for mobile payments, which others do. The touch sensitive button works well, though.

But this is the cheapest Fitbit, so you can't expect every feature. For £84.99 I'd say it's a little overpriced, but I really enjoy wearing it and am impressed with the sleep tracking data it collects (the diminutive Inspire 3 is the most comfortable Fitbit to wear at night). At the time of writing you can .

Yes, especially at a discount. This remains one of the best fitness bands for casual health tracking. If you don't need built-in GPS to track runs, this comes recommended.

• Released: September 2022
• RRP: £139.99
• Good: Built-in GPS, contactless payments
• Bad: GPS accuracy, small screen

For a few sheets more, you can opt for the Fitbit Charge 6. It has a larger screen than the Inspire 3 (though notifications are still cramped to read) and adds in built-in GPS to track runs without your phone - with the caveat that I found this GPS quite average, with some drop outs and inaccurate route measuring, but it mostly gets the job done.

It also adds ECG for heart rhythm assessment, Google Maps on-wrist directions, Google Wallet for contactless payments, skin temperature sensor to track stress (something the pricier Versa 4 lacks) plus YouTube Music controls.

Unfortunately, Google decided to take away control of any other streaming service or media playing on your phone from Fitbits, only supporting YouTube Music. It's an annoying and cynical decision, but weirdly only the Charge 6 can do it, perhaps as it's the most recently released Fitbit.

Impressively, the Charge 6 is the only Fitbit that can broadcast your heart rate to certain gym equipment, making it a great choice for gym rats on a budget.

As you'd expect, the Charge 6 can track more than 40 different activities and sports, more than the Inspire, and data is well presented in the Fitbit app. I found the battery lasted about four or five days of use with the always-on screen turned off, less if it's on.

Yes, if you want a slim tracker with good battery life and GPS. The Charge 6 actually has more features than the pricier Versa 4.

• Released: September 2022
• RRP: £179.99
• Good: Slim and light, larger screen
• Bad: No third party apps

The Fitbit Versa 4 is essentially a Fitbit Charge 6 with a larger screen and fewer features. This makes it difficult to fully recommend at its £179.99 price point, especially because it's a large screen watch with no access to third-party apps that you can get on an Apple Watch or Google Pixel Watch.

It's best to think of the Versa 4 as a fitness tracker that looks like a smartwatch. I really enjoy wearing it as it's lightweight, has a nice bright display and a physical button on the side that's easier to press than the touch sensitive ones on the Inspire 3 and Charge 6.

Battery life is strong at about six days, but I am more inclined to turn on the always on screen on the Versa 4 because it looks like a watch. This roughly halves the longevity, but it still beats most smartwatches. Then again, it can't do too many smart things, though you get the Google Maps and Google Wallet apps, plus a Fitbit tile on the watch to help you track your menstrual cycle.

It's a good choice if you want to track all your exercise, plus it has built-in GPS, though its not as accurate as comparatively priced Garmin or Apple Watch models.

The larger screen is far preferable to the smaller Fitbits for viewing your live stats when on a run. That display space also makes the notifications received from your phone far easier to read, but I turned them off as you can't interact with them because, remember, this isn't really a smartwatch.

Only if you want a fitness tracker that looks like a smartwatch. If you don't need the larger screen, the Charge 6 is a better buy. If you want an actual smartwatch, don't buy a Fitbit at all.

• Released: September 2022
• RRP: £219.99
• Good: ECG, premium design
• Bad: Stress tracking, expensive

I must caveat this assessment by saying I have not used the Fitbit Sense 2 since late 2023, but I am confident in this write up because of my time with it, and the fact it is practically the same device as the Versa 4. The Sense 2 adds an ECG sensor for heart rhythm assessments and a temperature sensor to help monitor stress levels. Otherwise, it's exactly the same as the Versa.

I found the stress tracking initially interesting but eventually turned it off. The idea is you keep the tracking on 24/7 and if the Fitbit senses a change in skin temperature it pings you to ask what emotion you were feeling from a list. The issue is, it notifies you several minutes after the change so you may have forgotten the trigger. Also, receiving a notification on your watch asking you why you are stressed is, believe it or not, quite stressful.

Otherwise, the Sense 2 is an overpriced Fitbit for what you get. Without any third party apps (lest we forget the original Sense could download some such as Spotify until Google nuked that for everyone) it's an expensive fitness tracker. You can buy an Apple Watch SE for £219, the same price, which offers far more advanced health tracking, better GPS accuracy, and scores of third party apps.

Like the Versa 4, the Sense 2 can help you track your menstrual cycle on-device, and all health data is well collected and presented. The display makes it a pleasant device to use.

No, unless you really want a Fitbit branded device with all the features it provides and don't mind the price.

Yes, all the Fitbit products in this article are water resistant up to 50 metres.

Every Fitbit has an accelerometer for measuring your step count, the core reason to buy a Fitbit for many customers. Each model also has a built-in vibrating alarm, which is very useful, and a heart rate sensor for tracking your BPM.

At the time of writing in April 2025, all four of these Fitbits are still receiving occasional software updates.

Yes, and both platforms get all features. The only extra thing Android users can do is reply to texts with quick replies, which doesn't work when the Fitbits are connected to an iPhone.

Only the Fitbit Charge 6 can be used to control YouTube Music. It can't control any other media playing on your phone, and neither can any other Fitbit.

Fitbit locks some functionality and features behind a paywall, so you also need to consider if you are willing to pay £7.99 per month for Fitbit Premium.

I don't think you need to. It provides video coaching sessions, more details on your sleep tracking rather than just a score, and similarly more in depth looks at your stress. You can also access healthy recipes and some mindfulness and meditation sessions. These are all nice to have, but aren't essential to enjoying the Fitbit app free of charge.

Recently, Fitbit also decided to make the Daily Readiness Score free in the Fitbit app for all users. It used to be locked to Fitbit Premium, but isn't anymore, providing a score out of 100 based on your activity and rest to recommend if you should exercise that day or not.
