I used AutoSleep on iOS for a few weeks. Each morning I’d get a notification with how “well” I slept, and a percentage of either “Sleep credit” or “Sleep debt”. I stopped using the app after a few weeks because this data was not really actionable. The more actively I tried to sleep the less I slept because my mind was busy thinking about needing to sleep. The sleep debt percentage also wasn’t helpful. If I struggled to sleep then having the app tell me I was 30% in sleep debt made me feel extra tired in the day. We don’t need to measure everything with data.
