Would be 5 w more free options to try.

I was amazed to see it actually worked! Not only did it work, it was spot on! Last night was my second night using this alarm and the first time I relied on it to wake me at 4:45 a.m. for work (which isn't easy.) I usually set the phone across the room on full volume with some loud song set to play, which takes years off my life as i jump out of bed b4 waking the whole house! This a.m. I came to (with a little bit of panic at first not knowing what time it was since again im used to being shocked awake. I looked at the clock (which was right next to me:) and it had literally awoke me exactly 10 seconds before my "fail safe" alarm went off. 5 stars once we can try out payed features b4 buying. And people will pay $5 mo. for a good night sleep


this app has saved my life during the school year! being in school I'm usually up all night studying (or on my phone) and than I have to wake up at 6 am. using a regular alarm clock was a struggle and I would always hit snooze. but since this can monitor when you're sleeping your lightest, it makes it so much easier to wake up so you're not in a deep sleep when the alarm goes off! I love that the music slowly progresses louder to help wake me up, and that to snooze all you have to do
is lift it and turn it back face down. I also love that you have to hold the button to turn off the alarm as I probably wouldn't wake up otherwise. overall I love love LOVE this app! it has saved me from lots of tiredness and being late to school!

I just want to go to sleep, not look at an ad

This app has prettier, more colorful, graphics but Sleep Cycle, by Northcube AB, does the same thing, was doing it first, and does it better. Unfortunately, Sleep Cycle does not integrate into Apple Health, and for me that was a fatal flaw. Despite the shortcomings that others have noted in their reviews, I liked it enough to keep using it. Since the upgrade, however, I have not been liking this one as much. Today's request that I rate it has pushed me over the edge. My chief complaint has to be the full screen ads that pop up just when you want to go to sleep. I doubt that these ads have a very high click through rate, because *I* *JUST* *WANT* *TO* *GO* *TO* *SLEEP*!!! Looking through the App Store, I can see at least two other programs that offer the same functionality, including Apple Health integration.
