Using smart watch to see if your asleep to stop the podcast/song with no need for timer

[Yonfloper]

If you can take that information of when you exactly fall asleep from an Apple Watch or any other smart watch you can decently stop the sound when your asleep without the need to put a timer every time agian or reset if you didn’t sleep in the time of it. It will help me with my tinnitus shimmer and keep the battery on my phone! It can be used in flights and other areas too!
