Thread: Using a SmartWatch to wake at the end of a REM cycle?

Hmmm, but unless I'm badly mistaken, the Smartwatch also collects data related to temperature and heart rate. At any rate, you give the app permission to access that information! And it also drains the watch battery like crazy, which indicates that it's monitoring those things all night. I could be wrong, I only started setting it up yesterday, and it's a bit of a curve.

I hate having it in my BEDROOM. I had some issues with wasting time with a phone in the mornings, and only got over it by locking it away in a cupboard and not accessing it til after yoga, journalling, meditation, coffee and breakfast. After that, I felt strong enough to face the day's headlines. I really don't like having a phone anywhere near me at night. Too tempting.

PS The developers of the Sleep as Android app already have some kind of mask with lights in it. They have a pipeline section somewhere that says they'd like to add sensors in it to detect eye movement. If they got that done, it would definitely be interesting!
