Sleep staging
4-stage via Zepp
The $50 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 $150: a bright AMOLED screen, 18-day battery, blood-oxygen monitoring, and Zepp's respectable sleep-stage breakdown for about $50. 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.

Frequently asked questions
Is $50 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.
