Withings Sleep review

Withings Sleep is the low-effort choice: you slide a 5mm pad under your mattress, plug it in, and it tracks every night without charging or wearing anything. A pneumatic sensor measures heart rate, breathing rate and movement through the mattress, and a sound sensor picks out snoring and breathing disturbances. The app shows sleep duration, how long you took to fall asleep, time to wake, deep, light and REM cycles, continuous heart rate and snoring duration, all rolled into a Sleep Score. That makes it good at showing what interrupts a night, especially for people who suspect snoring. Withings says it developed the device with sleep physicians at Hôpital Béclère in Paris and tested it against polysomnography. The limits are physical: it stays in one bed and does not track daytime activity. Basic data is free, while Withings+ adds a readiness score and coaching for $99.50 a year, with one month free.
