re: Does anyone else use an app as a sleeping aid or alarm

The app doesn't know what cycle you're in. It is designed from knowledge of typical sleep patterns in that you go in and out of deep sleep and your level of consciousness is greater the further you are from deep sleep. You can adjust the length of the alarm.

My current profile is set to 5 min Fade-in and 10 min of alarm at 70% volume. It also turns on the display at the alarm time after fade in to 50% brightness
