The Sleep Cycle app does a pretty good job at sleep analysis and gentle waking and you don't have to wear anything.

- calvinbhai 9y agoI was a first adopter for this app, and I have seen way too many scientific journals / papers by PhD candidates or from researchers saying that the Sleep Cycle app is not anywhere close to identify the correct sleep cycles. After using it for a few years, I stopped using it because how I felt in the morning had no correlation to what the app was saying how my sleep was.
