Amazfit Band 7 Fitness Tracker
Best for: Cheapest credible sleep tracker, marathon battery
The budget sleep tracker — 18-day battery, SpO2 and genuinely usable sleep staging at a price that makes trackers impulse-buyable.
The Band 7 proves credible sleep tracking no longer costs flagship money: a bright AMOLED screen, 18-day battery, blood-oxygen monitoring, and Zepp's respectable sleep-stage breakdown at a budget price. It's plasticky and the app pushes premium upsells, but as a first tracker or a no-worry beater for the gym and bed, nothing touches the value.

How our prices work
We show the price at our recommended retailer and, when Amazon reports one, its list price for comparison. Amazon prices come from Amazon's own product data service and are refreshed twice a day; each one shows the date and time Amazon gave it, and one older than 24 hours is replaced by “Check price”. Other retailers' prices are checked by hand and show the date of that check. Retail prices move constantly, so the price on the retailer's own page at checkout is the one that applies.

Frequently asked questions
Is budget tracking any good?
Surprisingly yes — the staging agrees with pricier bands more often than the price suggests. You lose polish and coaching, not core function.
Band 7 vs Fitbit Charge 6?
Charge 6 has better sensors, ecosystem and staging; Band 7 costs a third and lasts three times longer per charge. Budget-first: Band 7.
SpO2 reliable?
Fine for trends, not medical spot-checks — same caveat as every wrist SpO2.
Battery honestly 18 days?
With always-on display off, yes 12-18 days — genuinely the best in the value tier.
