FAQs

Are sleep trackers actually accurate?

Premium trackers like Oura and Apple Watch detect sleep stages with 80–90% accuracy compared to clinical polysomnography. Budget trackers are less reliable.

Do I need to wear something to track sleep?

No. Under-mattress sensors like the Withings Sleep Analyzer track sleep without wearing anything. They also measure snoring and breathing disturbances.

Can a sleep tracker actually improve my sleep?

The data alone does not improve sleep, but it highlights patterns — like late caffeine or inconsistent bedtimes — that you can then change.
