Sleep Cycle user reviews :

I’ve been using this for a while now. I don’t find the quality judgement to be accurate. I travel a lot so the surface I sleep on changes among other things. Also for people who share needs it is worth noting it will likely register both peoples movements. But it’s still a 5 star app to me: I love having a noise gradually get louder, the snooze is intelligently spaced and having a tone frame to wake up I feels great. Trains you to wake up naturally. If you let it wake you up on the earlier side when it deems fit you’ll find you feel great after 5 minutes.

I like the app, I’ve woken up early 75% of the time feeling refreshed because of it. I just wish Android version had Hue Integration and I can’t seem to find any snore detection. Two of the three things I wanted this app for are not there.
