Best Wearables Under £100 in 2026

You do not need to spend £300 on an Apple Watch or £250 on an Oura Ring to get meaningful health tracking. The budget wearable market in 2026 is remarkably competitive, with devices under £100 offering heart rate monitoring, sleep tracking, SpO2, and even basic GPS. Here are the best affordable wearables available right now.

Fitness Bands

The Xiaomi Smart Band 9 is, based on reviewer consensus, the single best value proposition in wearable technology. For approximately £35, you get a bright 1.62-inch AMOLED display, continuous heart rate monitoring, blood oxygen tracking, sleep analysis with REM detection, stress monitoring, and up to 21 days of battery life. According to manufacturer specifications, it supports over 150 workout modes and is water-resistant to 50 metres.

Based on published reviews, the tracking accuracy is impressive for the price point. Heart rate monitoring is reliable during steady-state activity, though it can lag behind during interval training compared to premium devices. Sleep tracking identifies sleep stages with reasonable accuracy, and the Mi Fitness app provides clear data visualisation. The main compromises are the lack of built-in GPS (it uses connected GPS from your phone) and a notification experience that is functional but limited compared to a full smartwatch. For anyone who wants basic health tracking without spending more than a restaurant meal, the Smart Band 9 is the obvious choice.

Amazfit's Band 7 offers a compelling alternative to Xiaomi with a 1.47-inch AMOLED display that supports always-on mode — a feature you rarely see at this price. According to manufacturer specifications, it tracks heart rate continuously, monitors blood oxygen, provides sleep staging analysis, and includes Amazfit's PAI (Personal Activity Intelligence) score, which distils your overall activity into a single motivational number.

Based on published reviews, the Amazfit Band 7 is slightly more polished than the Xiaomi in terms of software, with the Zepp app providing more detailed health insights. The 18-day battery life with always-on display off (or around 7 days with it on) gives you flexibility. Like the Xiaomi, it lacks built-in GPS. According to reviewer consensus, the Band 7 is the better choice if you value a larger display and always-on functionality, while the Xiaomi wins on pure battery life and price.

At the top of the under-£100 range, the Fitbit Inspire 4 brings Google's health ecosystem to a budget price. Based on manufacturer specifications, it includes all the sensors you would expect — heart rate, SpO2, sleep staging — but adds an EDA (electrodermal activity) sensor for stress detection, which is rare at this price point. It also comes with six months of Fitbit Premium, which includes guided workouts, detailed sleep insights, mindfulness sessions, and a Daily Readiness Score.

According to published reviews, the Fitbit app remains one of the best health and fitness platforms available, with strong community features (challenges, social sharing) and a clear, motivational interface. The 10-day battery life is solid, and the slim design is comfortable enough to wear 24/7. The main drawback, based on reviewer consensus, is that after the Premium trial ends, some of the best features become locked behind a monthly subscription. However, even without Premium, the Inspire 4 provides excellent basic tracking and a significantly better app experience than Xiaomi or Amazfit.

Budget Earbuds

The Nothing Ear (a) is the budget sibling of the Ear (3), and based on published reviews, it punches remarkably close to its more expensive relative. Adaptive ANC with up to 40dB of noise reduction, LDAC high-resolution Bluetooth audio, and 11mm custom drivers are features you would expect at twice the price.

According to reviewer consensus, the sound profile is warm and engaging with decent bass, making it well-suited to most music genres. The transparent design with the signature dot-matrix pattern gives them a distinctive look. The main trade-offs compared to the premium Ear (3), based on published comparisons, are slightly less effective ANC, an IP54 rating instead of IP55, and no wireless charging on the case. But at £79, these are among the best-value earbuds available. For more on hearables, see our full hearables buying guide.

Budget GPS Watches

If you want built-in GPS without spending a fortune, the Amazfit Bip 5 is the most affordable option worth considering. According to manufacturer specifications, it offers four-satellite GPS positioning, which means you can track outdoor runs, walks, and rides without carrying your phone. The 1.91-inch AMOLED display is large and bright for the price, and it even supports Bluetooth phone calls.

Based on published reviews, GPS accuracy is reasonable for casual runners — it will not match a Garmin Forerunner or Apple Watch Ultra, but for tracking your 5K route and getting approximate pace data, it is more than adequate. The 10-day battery life in smartwatch mode (or approximately 26 hours with continuous GPS) gives you genuine flexibility. According to reviewer consensus, the Bip 5 is the ideal first GPS watch for someone who is not yet ready to invest in a dedicated running watch but wants to track outdoor workouts independently.

What You Give Up at Under £100

Budget wearables are remarkably capable in 2026, but there are genuine compromises. Here is what you should expect to miss compared to premium devices (see our tracker vs smartwatch comparison for more):

• ECG and advanced health sensors. No budget wearable offers electrocardiogram readings or hypertension detection.
• Premium GPS accuracy. Multi-band (L1+L5) GPS is not available under £100. Single-band GPS is good enough for most casual use but less precise in urban canyons and dense tree cover.
• App ecosystem depth. You cannot install third-party apps on fitness bands. Notifications are basic — you can read them but usually cannot reply.
• Build materials. Expect polycarbonate and aluminium rather than titanium and sapphire glass. Budget wearables are durable enough for daily use but will not survive serious outdoor abuse.
• Display brightness. Outdoor visibility in direct sunlight is noticeably worse on budget displays compared to the 2,000-3,000 nit screens on premium watches.
• Sensor accuracy. Heart rate monitoring during high-intensity interval training and sleep stage detection are both less accurate on budget devices. For steady-state activity and general sleep tracking, the difference is marginal.
