Top Fitness Trackers Under £100 UK
#1, Fitbit Charge 6 Activity Tracker
If you’re after a fitness tracker that just quietly gets on with the job, the Fitbit Charge 6 is the grown-up in the room. It’s not out to grab attention with flashy extras, but it covers almost everything you’d want and does it well. For under £100, it’s packed with features: you get built-in GPS (still a rarity at this price), more than 40 exercise modes, automatic workout detection, and heart rate tracking you can actually trust. Plus, there’s a sweetener, six months of Fitbit Premium included.
The battery easily lasts about a week, so you’re not constantly chasing a charger. It’s water-resistant up to 50 metres, meaning rain, showers, and sweaty gym sessions are all in a day’s work. But what really makes the Charge 6 feel a cut above is how connected it is. Having Google Maps, Google Wallet, and YouTube Music controls on your wrist makes daily life that bit smoother, and it handles calls, texts, and app notifications like a lightweight smartwatch.
If sleep tracking matters to you, the Charge 6 does a solid job especially with Premium. You’ll get detailed sleep scores, smart wake-up alarms, and readiness insights that might just help you tackle Monday mornings (or at least understand why you don’t want to). No, it’s not the cheapest here, but if you’re looking for something accurate, dependable, and polished from a brand you already know and trust, the Charge 6 is probably the safest choice under £100.
#2, RUIMEN Smart Watch Health Tracker
Seriously Affordable and Surprisingly Good, Let’s be real - when you spot a fitness tracker going for less than £50, you’re probably not expecting miracles. But the RUIMEN Smart Watch manages to quietly overdeliver. It’s a crowd-pleaser for a reason. With its big, bright 1.85-inch HD touchscreen, it looks like it costs twice as much and covers all the basics most people actually care about. You get step counting, calories, heart rate, sleep tracking and SpO2 monitoring, and for everyday use, they all work just fine.
A standout feature here is the Bluetooth calling, you can answer or make calls right from your wrist, which is a neat trick for a budget tracker (even some pricier ones skip this). You’ll also see message and app notifications pop up, though you can’t reply but at this price, that’s understandable.
If you’re someone who likes to mix things up, the app’s got more than 100 sport modes. Whether you’re dabbling in new activities or just like to keep track, there’s plenty of choice. The battery lasts about 5 to 7 days, depending on how much you poke at it or show it off.
It’s worth mentioning: there’s no built-in GPS, and the waterproofing is more “splash-resistant” than truly swim-proof. Hardcore runners and swimmers might want to keep looking.
But for anyone just starting out, casual users, or those who want a load of features without spending a fortune, it’s a fantastic deal. Cheap doesn’t always mean cheerful, but in this case, it absolutely does.
#3, Google Fitbit Inspire 3 Activity Tracker
Subtle, Powerful, and Incredibly Practical – If you’re after a fitness tracker that’s light, comfortable, and doesn’t shout for attention, the Fitbit Inspire 3 is a real gem. It’s the sort of device you’ll barely notice on your wrist until it gives you a gentle nudge to get moving after you’ve been sitting for a while.
Don’t let its slim size fool you, though. The Inspire 3 is packed with genuinely useful health features: round-the-clock heart rate tracking, SpO2 monitoring, stress management scores, and Fitbit’s famously detailed sleep tracking, complete with a breakdown of your sleep stages and smart alarms to ease you out of bed. There’s also a complimentary six-month Fitbit Premium subscription included, giving you access to even more detailed insights and guided wellbeing tools.
What really sets the Inspire 3 apart is its battery life. A single charge can see you through up to 10 days outlasting plenty of chunkier rivals. It’s water-resistant up to 50 metres, so you don’t have to worry about taking it off for showers or swims. You’ll find over 20 different exercise modes, automatic activity tracking, and Fitbit’s Daily Readiness Score, which tries to gauge whether you should push yourself or take it easy that day.
Bear in mind, the screen is quite petite at just 0.7 inches, so if you prefer a big, flashy display, this might not be for you. There’s no built-in GPS either, so runners will need to bring their phones along for accurate tracking. Still, if comfort, solid battery life, and trustworthy health data matter more to you than bells and whistles, the Inspire 3 is a brilliant pick for under £100.
#4, Amzhero Health Fitness Tracker
Looking for a feature-packed fitness tracker that won’t empty your wallet? The Amzhero Health Fitness Tracker is proof that you don’t have to splash out for a solid wearable these days. Priced at less than £50, it’s a go-to for those who want plenty of tools without paying for a fancy logo.
Health tracking is where this little device shines. You get round-the-clock heart rate monitoring, SpO2 checks, sleep tracking, and even blood pressure readings. While you should take the numbers as helpful hints rather than medical advice, it’s impressive to get this much tech for the price.
There are 24 sports modes to keep you covered whether you’re swimming (it’s waterproof up to 5ATM), hitting the gym, or just heading out for a walk. You’ll get notifications for calls, texts, and your favourite apps right on your wrist, plus those handy reminders to move if you’ve been sitting too long (we all need a nudge sometimes).
Battery life won’t let you down either. With up to 15 days on standby, lighter users can easily go a couple of weeks before needing a charge. The 1.47-inch touchscreen is crisp and lets you pick from loads of different watch faces in the app. It doesn’t have built-in GPS and the app isn’t as slick as some pricier brands, but for the money, it’s hard to complain. All in all, it’s a fantastic starter fitness tracker for beginners, teens, or anyone keen to keep tabs on their health without breaking the bank.
#5, HUAWEI Band 10 Smartwatch Tracker
The Battery-Life Champion With a Brain – If you’re someone who can’t be bothered charging gadgets every night or you’re serious about tracking your sleep, the HUAWEI Band 10 is well worth a look. For less than £100, it’s a real standout thanks to its incredible battery life, comfort, and in-depth sleep tracking. Huawei has really focused on recovery and overall wellbeing with this band. The sleep tracking isn’t just a box-ticking exercise you get proper insights like average sleep HRV, breathing quality, and SpO2 readings. It doesn’t just say “You slept badly,” it actually digs into the reasons why, which is refreshingly useful.
Even with all those sensors inside, the Band 10 barely weighs anything (just 15g and only 8.99mm thick), so you’ll barely notice it whether you’re wearing it all day or all night. It’s comfy enough that even people who usually rip trackers off halfway through the night will likely forget it’s there.
The battery life is seriously impressive. A quick five-minute charge can see you through two days, and a full charge will easily last up to two weeks if you’re not hammering it with notifications. If you’re tired of having to plug in your tracker every single night, this is a real breath of fresh air. Fitness tracking is no afterthought either, the Band 10 packs a clever 9-axis sensor and uses AI to accurately track over 100 different sports, including swimming. It’s not pretending to be a full-on smartwatch, but as a health and fitness band, it’s more than capable.
The display is bright and easy to read, you can swap out watch faces, and the band itself comes in various colours and straps, so you’re not stuck with something boring or basic.
Conclusion – Which Fitness Tracker Should You Pick?
Honestly, there’s no real “wrong” choice under £100 these days, but each tracker shines in its own way.
