Battery life	21 days
Water resistance	5ATM
GPS	No
Sensors	6-axis sensor, Dual-channel PPG biosensor with heart rate and SpO2 monitoring

The Xiaomi Mi Band 9 is an ultra-affordable fitness tracker that’s perfect for those on a budget. Despite its low price, it still packs an impressive range of health and fitness tracking features. We’re big fans of its sleek, minimalistic design and even bigger fans of its exceptional battery life – lasting up to an incredible 21 days on a single charge.

Beyond its affordability and longevity, the Mi Band 9 delivers accurate tracking for daily activities, including steps taken, calories burned, and sleep monitoring. It also includes heart rate and SpO2 tracking, making it a well-rounded choice for basic health insights. Naturally, at this price point, it skips some premium features like built-in GPS and personalised coaching, but given its budget-friendly nature, that’s an understandable trade-off.

3. Whoop

Whoop specs
Screen	N/A
Battery life	5 days
Water resistance	5 ATM
GPS	No
Sensors	Accelerometer, Heart rate, Pulse Oximeter (SPO2), Skin Temperature Sensor
Compatibility	Android and iOS
Weight	16 g

The Whoop is unlike any other fitness tracker we’ve used – it’s not just about counting steps or checking your heart rate. Instead, it focuses on optimising your recovery, training, and sleep with in-depth data and personalised insights. There’s no screen, no distractions – just a sleek, comfortable band that tracks everything 24/7. We love that it helps us understand when to push harder and when to rest, something most fitness trackers overlook.

Its strain and recovery tracking are game-changers, especially for athletes or anyone serious about performance. The detailed sleep analysis is another highlight, showing how well you’re actually recovering.

The (rather expensive) subscription model means it’s not the cheapest option, but if you’re serious about optimising your fitness and well-being, it’s worth it. It also means constant updates and improvements.

Really, Whoop is more than a tracker – it’s a coach on your wrist.

4. Garmin Vivosmart 5

Garmin Vivosmart 5 specs
Screen	0.41×0.73in OLED touchscreen, 88×154 pixels
Battery life	7 days
Water resistance	5ATM
GPS	No
Sensors	Heart rate, blood oxygen, accelerometer, ambient light
Compatibility	Android and iOS
Weight	24.5g (small), 26.5g (large)

If you’re after Garmin’s excellent fitness tracking app’s features but don’t want to spring for one of its pricey watches, then we think something like the Vivosmart 5 could be the ideal solution. It’s pretty smart, as far as fitness tracking bands go, thanks to a pared-back design and textured rubber shell.

Feature-wise, it ticks most boxes, including the usual fitness and sleep-tracking skills, along with a pulse oximeter, stress tracker, and Garmin’s body battery energy monitor. The addition of smartphone notifications and music controls also lends it some smarter functionality, without entering full smartwatch territory.

In our review, we found the battery life is decent, if not great, with around 7 days of use per charge on offer. If you’re set on using Garmin’s well-established app, then this could be one of the best entry points before potentially upgrading to something more fully-featured in future.

Water resistance	5ATM
GPS	No
Sensors	3-axis accelerometer, optical heart rate monitor, red and infrared sensors for blood oxygen (SpO2) monitoring, ambient light sensor
Compatibility	Android and iOS
Weight	17.7 g

With a great battery life, minimal-yet-smart design, and a price that’s at the more affordable end of Fitbit’s lineup, the Inspire 3 has plenty going for it.

Sure, you won’t get more advanced features like sweat-based stress tracking or GPS for phone-free runs, but if you want to enter the world of Fitbit’s tried and tested ecosystem while tracking activities, sleep, steps and more, the Inspire 3 won’t let you down.

6. Withings ScanWatch 2

Withings ScanWatch 2 specs
Screen	Analogue dial + small PMOLED screen
Battery life	30 days
Water resistance	5 ATM
GPS	No
Sensors	Multi-wavelength PPG heart rate/SpO2 sensor, stainless steel electrodes, MEMS 3-axis accelerometer
Compatibility	Android and iOS
Weight	58g (38mm), 83g (42mm)

We’re big fans of the Withings ScanWatch 2, as it continues the brand’s unique approach to blending fitness tracking, smartwatch functionality, and classic timepiece design. With its traditional analogue face and discreet built-in display, it delivers the charm of a conventional watch while packing advanced health-tracking features, including an ECG sensor, SpO2 monitoring, body temperature tracking, and sleep apnea detection. This makes it one of the most comprehensive hybrid smartwatches on the market.

Alongside these advanced health metrics, it offers 24/7 activity tracking, heart rate monitoring, and in-depth sleep analysis, making it a fantastic choice for fitness enthusiasts who prefer a more understated look.

And thanks to the lack of a large, power-hungry display, it boasts an exceptional battery life of up to 30 days on a single charge—putting most other smartwatches to shame. If you want cutting-edge health insights without sacrificing style, the ScanWatch 2 is an easy recommendation.

How to choose the best fitness tracker for you

Overwhelmed by the vast choice of fitness trackers out there? Fear not, for Stuff’s wearable experts are on hand to grace you with their expertise.

The first step is deciding on a form factor — we’ve gone mostly for more minimalist “band”-type trackers, as they’re fitness-focused rather than offering all the apps, bells, and whistles served up by, say, some of the best Android smartwatches. That’s not to say you can’t opt for a smartwatch, mind. In fact, we’ve included the likes of the Apple Watch SE above as it’s a great choice for iPhone users looking for fitness tracking and other smarts in one device.

For the most part, though, you’ll want something compact, thin, and light, with a smartwatch-beating battery life of around five days or more. Waterproofing is a must if you’re swimming, and practically every fitness tracker is weather/sweat-resistant at the very least, for obvious reasons.

Built-in GPS is a bonus if you’re looking to track outdoor activities without having to bring along your bulky smartphone, and other extras like music playback can come in handy for the same reason.

With most fitness trackers offering the same core experience — namely, steps counted, calories burned, heart rate, sleep tracking, activity tracking, and more, you’ll want to decide on which brand you feel most comfortable with. Some fitness trackers offer more comprehensive stats for particular sports like swimming, and if you’ve already got a device from a particular brand, you may want to stay within their ecosystem so that you don’t lose any of your existing app data.

Fitness trackers vs smartwatches

Fitness trackers and smartwatches both offer fitness tracking, but they serve different needs. Fitness trackers are typically smaller, lighter, and designed primarily for health monitoring. They focus on essentials like step counting, heart rate tracking, sleep analysis, and sometimes SpO2 and stress monitoring. Many fitness trackers also have longer battery life, often lasting a week or more.

Smartwatches, on the other hand, combine fitness tracking with a wider range of features, including notifications, apps, and sometimes even music storage or phone calls. They often have built-in GPS for precise workout tracking and larger, interactive displays. However, they tend to be bulkier and require more frequent charging—sometimes daily.

If you want a simple, dedicated fitness tracker with minimal distractions and long battery life, a fitness band is ideal. But if you prefer an all-in-one device that blends fitness with smart features, a smartwatch might be the better choice (read Stuff’s guide to the best smartwatches).
