Sleep Cycle is accurate at tracking the consistency of your sleep schedule. It's similar to documenting your sleep patterns with a sleep diary and monitoring it with an actigraph. At a cost of 99 cents, though, it's much less expensive than actigraphy.May 7, 2020
Is Sleep Cycle a good app?
Unlike SleepScore, Sleep Cycle doesn't show how long you were in each stage of sleep. It also doesn't give you any advice for improving your sleep. But this app's clean graphs let you easily see general trends—which may be all you need to understand your patterns.
