Decent… could improve

Does a decent job. Not as accurate on sleep phases as Sleep Cycle alarm clock, but does a good job of waking you up before you risk over-doing your nap. Would be nice if it also did some level of monitoring and such stats could be integrated with the main (alarm clock) app… but this is an understandably different challenge with the phone in your pocket rather than on your mattress. Hoping to see improvements.
