The cheapest interesting question in wearables right now: do you want a screen or not? Xiaomi's Smart Band 10 gives you a genuinely lovely 1.72-inch AMOLED display, 21 days of battery and 150-plus sport modes for about $48. Google's Fitbit Air deletes the screen entirely, halves the battery, doubles the price, and argues that what you actually wanted was better health data with fewer distractions.
Both are right for different people, and this is the comparison where being honest about your own habits pays off most.

The screen is the decision
Everything else follows from the display. The Band 10's AMOLED gives you the time, your heart rate mid-run, message previews and music controls, a tiny smartwatch for a twentieth of an Apple Watch's price. The cost is attention: every notification buzzes your wrist, and you will look, because that is what screens are for.
The Air is the counter-argument made physical. No screen means nothing to check, which is precisely why the screenless category exists; even Apple is reportedly exploring it, as we covered in our explainer on Apple's screenless tracker plans. You glance at your phone when you choose to, and the band's only job is to gather better data than a $48 device can: HRV, skin temperature, heart rhythm.
Health tracking depth
The Air's sensor suite is a class above: AFib alerts with cleared-algorithm heritage, HRV trends, temperature shifts that flag oncoming illness, and sleep staging refined across a decade of Fitbit research. The Band 10 covers the visible basics well, steps, heart rate, SpO2 spot checks, credible sleep stages, but it is a fitness band, not a health instrument. Nobody's cardiologist will ask about their Xiaomi.
Flip to pure fitness utility and Xiaomi punches back: 150-plus sport modes, live stats on the wrist during workouts, and a battery that survives three weeks of everything. For gym classes and runs where glancing at pace matters, the screen is not a luxury, it is the feature.
Value and the upgrade path
At $48 the Band 10 is the best pure value in wearables, full stop. The Air's extra $50 buys sensor depth and silence. Both export core data toward Apple Health and Health Connect, so either can feed apps like Fitcoin, which scores movement into FitScore and pays it back in partner rewards and Leagues; the Air's route is documented in our Fitbit Air rewards guide. Whichever you pick, the data does not have to sit idle in a chart.
Verdict: which one should you buy?
Choose Fitbit Air if:
- You want deeper health data: HRV, temperature, AFib alerts.
- You are buying screenless on purpose to escape notifications.
- Sleep insight quality matters more than on-wrist stats.
Choose Xiaomi Smart Band 10 if:
- You want the most tracker per dollar on the market.
- You like seeing time, stats and notifications on your wrist.
- Three-week battery life beats every other consideration.
- You are buying a first tracker and might not stick with it; $48 is a painless experiment.
Our take: the Band 10 is the better gadget, the Air is the better health product. Buy Xiaomi for your wrist, buy Google for your physiology.
Frequently asked questions
Is the Xiaomi Smart Band 10 cheaper than the Fitbit Air?
Roughly half the price: about $48 street against $99. Neither requires a subscription for core features.
What does the Fitbit Air have that the Xiaomi Band 10 lacks?
AFib heart rhythm alerts, HRV-driven health insights in Google Health, skin temperature tracking and the screenless design itself, which many people buy specifically to avoid wrist notifications. Google's sleep science heritage is also a step up in credibility.
What does the Xiaomi Band 10 have that the Air lacks?
A bright 1.72-inch AMOLED touchscreen for time, notifications, live workout stats and music control, plus roughly triple the battery life at up to 21 days and 150+ sport modes.
Which tracks sleep better?
Both stage sleep credibly for the price, but the Air's combination of HRV, temperature and Google's sleep algorithms gives it the edge for health insight. Xiaomi's strength is that its 21-day battery means you never skip a night to charge.
Do they work with iPhone and Android?
Yes, both. The Air pairs with the Google Health app; the Band 10 uses Mi Fitness. Both can export core data toward Apple Health and Health Connect for other apps to use.
