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! Time to go crush!",
