2. Xiaomi Mi Band 9

Xiaomi Mi Band 9 specs
Screen	1.62 inch AMOLED Touch Display, 192 x 490 pixels
Battery life	21 days
Water resistance	5ATM
GPS	No
Sensors	6-axis sensor, Dual-channel PPG biosensor with heart rate and SpO2 monitoring
Compatibility	Andoird and iOS
Weight	13.5g / 0.47 oz

The Xiaomi Mi Band 9 is the go-to choice if you want a fitness tracker that won’t break the bank. It’s slim, minimal, and surprisingly capable for its price. The real star is battery life – lasting up to 21 days on a single charge, it easily outperforms far pricier rivals.

Despite the low cost, it covers the essentials well. You get step counting, calorie tracking, sleep monitoring, plus heart rate and SpO2 for extra health insights. Accuracy is solid, making it a dependable daily companion.

Of course, there are compromises. There’s no built-in GPS or advanced coaching features, but at this price, that’s hardly a deal-breaker. If you want a simple, reliable, and long-lasting fitness tracker to get moving, the Mi Band 9 offers unbeatable value. If you want an easy way to stay on top of your daily activity without spending a fortune, this is one of the best options out there.

3. Whoop MG

Whoop MG specs
Screen	N/A
Battery life	14 days
Water resistance	IP68 (up to 10m)
GPS	No
Sensors	PPG heart rate, ECG electrodes, accelerometer, skin-temperature sensor
Compatibility	Android and iOS
Weight	27.3 g / 0.96 oz

We wore the Whoop MG non-stop for over a month, and it’s easily the most advanced fitness tracker we’ve tested – as long as you’re OK wearing an Apple Watch alongside it. The screenless band hides seriously smart tech, including medical-grade ECG and surprisingly accurate overnight blood pressure estimates. We calibrated it using a proper cuff and found the readings within 3 mmHg. That’s impressive.

We really liked waking up to meaningful insights instead of another vague sleep chart. Recovery scores often lined up with how we actually felt, and the daily “Optimal Strain” targets were weirdly spot-on – on green days we really did feel stronger. But auto-detection let things down. It spotted our runs, but missed most strength workouts unless we logged them manually. That meant relying on our Apple Watch for reliable tracking, which defeats the purpose somewhat.

The companion app’s a highlight – slick, insightful, and genuinely helpful – especially the Daily Outlook and Journal tools. But only the included strap unlocks ECG, which feels limiting.

With two-week battery life, a featherweight feel, and real health insights, the MG is a serious tool. Just know you’ll be paying handsomely for it – both upfront and every year after.

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 / 0.86 oz (small), 26.5g / 0.93 oz (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.

5. Fitbit Inspire 3

Fitbit Inspire 3 specs
Screen	72x128px AMOLED
Battery life	10 days

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 / 0.62 oz

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.

The Withings ScanWatch 2 nails the hybrid smartwatch formula, combining classic looks with cutting-edge health tracking. Its analogue face hides a discreet display that delivers notifications and stats without spoiling the traditional watch aesthetic.

Health features are where it shines. You get ECG, SpO2, body temperature tracking, and even sleep apnea detection – making it one of the most advanced hybrids available. It also covers the basics with 24/7 activity tracking, heart rate monitoring, and detailed sleep analysis.

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 go beyond fitness tracking, offering notifications, apps, and even extras like music storage or phone calls. Many include built-in GPS for accurate workout tracking and feature larger, interactive displays. The trade-off? They’re bulkier and often need charging every day.

If you want a straightforward fitness tracker with long-lasting battery life and minimal distractions, a fitness band is the better pick. But if you’d rather have a do-it-all device that balances health features with smart functionality, a smartwatch makes more sense (read Stuff’s guide to the best smartwatches).

Which fitness tracker has the best health app?

Every fitness tracker app has its strengths, but Oura’s stands out. It focuses less on step counts and high-intensity workouts, and more on recovery, sleep, and long-term well-being. If you care about understanding how your body recharges as much as how it moves, Oura arguably offers the best overall health app experience.

The Oura app is slick, calming, and obsessively detailed. It’s less “rah-rah” motivation and more “here’s how your body’s really doing” – tracking sleep stages, readiness, heart rate variability, body temperature, and even stress with impressive accuracy. You get personalised insights without being bombarded by pushy alerts.

Fitbit’s app is more fitness-focused, gamified, and social. Garmin’s excels for performance stats and sports, though its interface is more utilitarian. Whoop is great for athletes, but its app can feel a bit intense if you’re not chasing PBs daily.

So, for thoughtful, science-backed health insights wrapped in a beautifully chill app experience, Oura leads the pack – especially if you like tracking, not just training.
