Awesome

Great app. Easy to use and has given me interesting information to help with my health.

Stopped recording after recent updates

Have used this app successfully for several years now. Sometime recently something changed. When I use the Lights Off feature on my iWatch, it keeps running after I rise in the morning. If I don’t turn it off manually, it’ll run all day until I go to use it again that night. For these days, there are no stats recorded for that night. Very bummed about this. Everything used to be automatic - now I have to remember to turn it off! Why?

Best Sleep Tracker I’ve Found

I work variable night shifts, so I often switch from daytime sleep to regular nighttime sleep. Apple’s sleep tracking penalizes you when you change routines, which just doesn’t work for night shift folks.

The analysis that AutoSleep provides also matches how I am actually feeling, whereas other apps have told me I’ve had a great nights sleep when I feel just awful and the other way around.

Definitely worth the price and no subscription is refreshing

What kind of sleep data does AutoSleep provide?
