Withings Sleep Tracking Mat

rec from a friend because it’s the best tracker she found where you don’t have to wear anything. it just works. you leave it between your mattress and boxspring (or whatever your mattress is resting on) and it is able to detect your heart rate and motion through your mattress??? i’m looking into it so i don’t have to charge a device and put it on as part of going to bed.

i ordered one ($99) and am waiting for it to arrive.
