Best Budget Fitness Trackers Under £100: Fitbit vs Xiaomi Smart Band 10 Pro

Affordable Fitness Tracker Basics: Who Are These For?

An affordable fitness tracker is a wrist-worn device that records everyday activity, health metrics, sleep patterns, and exercise sessions, often with built-in GPS and water resistance, designed to give practical health insights without the high price or complex features of premium smartwatches. In the budget smartwatch under 100 space, the bestselling Fitbit deal at £79 targets users who want straightforward budget health tracking, solid sleep monitoring and integrated fitness tracker GPS without paying flagship prices. The Xiaomi Smart Band 10 Pro, sold at a discounted RM289 on its official website, pushes harder into advanced fitness tracking with a bright AMOLED display, long battery life options and broad sports coverage while staying firmly in the budget wearable category. If you care most about simple, dependable health tracking, the Fitbit feels friendlier; if you want more screen and sport features, the Xiaomi band has the edge.

Design, Display and Everyday Use

The Fitbit bestseller focuses on comfort, basic smartwatch styling and clear at-a-glance data. It is water-resistant to 50m, offers around seven days of battery life, and is built to be worn all day and night for activity and sleep tracking. The display is adequate for checking steps, heart rate and notifications, but it does not try to compete with high-end smartwatch screens. In contrast, the Xiaomi Smart Band 10 Pro is built around a 1.74-inch AMOLED panel with 480 x 336 resolution, up to 2,000 nits peak brightness, a 60Hz refresh rate and over 200 watch faces, plus a high-strength aluminium frame and 5ATM water resistance. That makes it much closer to a full budget smartwatch under 100 in look and feel. The trade-off is usability: Xiaomi relies only on a touchscreen, which can be awkward with wet or sweaty hands, while the Fitbit’s simpler interface may suit users who value ease over visual flair.

Health Tracking, Sports Modes and GPS Performance

If you want budget health tracking, the Fitbit deal leans into essentials: all-day activity monitoring, heart rate tracking, and sleep monitoring that helps busy users understand their rest and recovery. It includes integrated GPS so walkers and runners can track routes and pace without carrying a phone, and it ships with three months of Google Health Membership, which adds extra guided insights and programs. According to one review, “The Amazon number one bestselling Fitbit is now £79, offering health tracking, sleep monitoring and GPS for more than £60 less.” The Xiaomi Smart Band 10 Pro raises the bar with an upgraded PPG heart rate sensor, a blood oxygen sensor, over 150 sports modes, dedicated pool and open water swim profiles, and built-in GNSS GPS noted for reliable and accurate route tracking as well as modest battery drain during workouts. Its sleep insights are described as lacking depth, though, so serious sleep optimisers may prefer Fitbit’s emphasis on night data.

Value for Money: Fitbit vs Xiaomi Band

Both devices are clear wins for anyone hunting an affordable fitness tracker instead of a premium smartwatch. The Fitbit becomes compelling when its limited-time price drops to £79, a 44% reduction from £139.99 that “puts a bestselling fitness gadget into a much lower price bracket”. At that point, you get health tracking, sleep monitoring, fitness tracker GPS and seven-day battery life for under £100, plus a simple experience that suits users who want to set it up once and stop thinking about settings. The Xiaomi Smart Band 10 Pro, priced at RM399 but currently RM289 on its official website, is praised as offering “exceptional value for the feature set on offer” in the budget wearable category. You pay less than typical premium watches yet get a lively AMOLED screen, wide sport coverage, dependable GPS and practical battery life options. The main trade-offs are its more basic smartwatch features and an inconsistent companion app, which might frustrate users who care about polished software more than hardware value.
