NOT really effective, but good idea

Not really sure what’s going on here. Set for half hour sleep or 1 hr max and goes off in half hour. Doesn’t really seem to be measuring anything. And The developers response is mistaken. I was awake for the half hour. NOT napping, so the response I nonsensical. 1 star!

Works amazing, somehow knocks you out almost instantly and wakes you when you set it. The snooze feature should be eliminated however

Doesn't work

I have used this several times and never been able to see the results, that this app claims to do.

Happy Nappy Appy

It’s a good nap, App I like it. I just wish it had how much sleep you’ve had. I don’t know what the clock thing means. I guess if it’s on the 15 on the side or left, it’s a 15. I wish I had how much sleep you had when you wake up you see it easily.

Finally…A good Nap app

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! Time to go crush!

Retain the info?

It would be nice to retain the information about how long I actually slept for a little while- maybe until I use the app again? 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.
