Having trouble getting a good night’s sleep? For $2.99, AutoSleep Tracker can report not just on the quantity of your sleep hours but on their quality. Simply wear your Apple Watch to bed.
The app monitors and records your total time asleep, your wake time, and your restless time, along with each phase of sleep such as light sleep and REM sleep. The app also keeps track of your heart rate during the night.
The next morning, you can check the data in the watch app and the iPhone app to see how the night went. If you’d rather not wear your watch in bed, you can still tell the app when you turn in and when you wake up so it can track your sleep.
