Frequently asked questions
How accurate are sleep trackers, really?
Total sleep duration, time in bed, and bedtime consistency are measured reasonably well. Individual sleep stages (light/deep/REM) agree with clinical sleep studies only about 60-70% of the time across every consumer device, including all five here. See our full breakdown.
Ring or wristband?
Rings (Oura, RingConn) tend to be more comfortable for side sleepers who dislike a band pressing into their wrist. Wristbands (Fitbit) have real screens for checking stats without a phone, and generally cost less.
Do I need a subscription?
Fitbit’s core sleep/activity tracking works without one. Oura requires $5.99/month after the first month. WHOOP is subscription-only, bundled with the hardware. RingConn’s standard features are subscription-free.

How we picked these: We did not physically test these five trackers. These picks are based on the manufacturer’s published specifications and Amazon’s aggregate rating and review-volume data — a large, hard-to-fake signal, even without hands-on testing. We’d rather tell you exactly how we know what we know than dress up a spec sheet as a lab report.
