I’m so tired today I didn’t remember it from one moment to another. My favorite, the best Sleep Cycle keeps it going back to the beginning. Granted, Power Nap doesn’t. I’ve picked up the sounds and apps advertised but still see their ads. I got the extras to get rid of the ads.",

"body": "First of all… meant to tap the 5 star. I like the ‘sleep time’ readout of how much and IF I did sleep.(with 20 min nap—which are perfect for me) I sometimes feel I didn't actually fall asleep — this is able to let me see that I did. *just now I felt I didn't sleep at all— but I feel SO much better, and yeah, the app shows I actually slept 27 of the 20 min. -Perfect!
