Sleep
Withings Sleep is an under-mattress sleep tracker for people who want to understand their sleep habits without wearing a watch or charging another device.
The slim sensor automatically tracks sleep cycles, heart rate, and snoring, then sends the data to the Withings app so you can see how long you slept, how often you woke up, and how your sleep quality changes over time.
It also provides a daily Sleep Score and can connect with compatible smart home devices to automate parts of your bedtime routine. Once it's set up, you can track your sleep simply by getting into bed.
