Since using this app, I have definitely noticed a difference in my sleep. I wake up feeling energized, refreshed, and less cloudy in the mornings. I love how it adds the amount of time it takes for me to go to sleep within the sleep cycle calculation. This app also sets an alarm directly to the default alarm app on my phone at the press of a button. There are no ads and it has a simple, easy to follow format. This app was definitely worth the download! Loved it!

The "about this app" section here says it gives you a notification at selected sleep time, but I don't see anything like that in the app; since that's the main reason I downloaded it, I am uninstalling. Seems like just a reverse calculator with clock inputs, essentially calculating the number of 90-minute intervals between two times. It does set a wake alarm for you using the system clock app, but nothing for going to sleep at a chosen time.

Lightweight, Simple to the point app. My sleep routine had devastated my professional life. I couldn't hear my alarms even though they rang continiously for 3 hours at a time. I read somewhere that sleeping in cycles makes sure that you wake up fresh and on time so i searched on playstore and this app popped up. Needless to say, I haven't missed a single alarm since I started using it. Highly highly recommend if you are a heavy sleeper and struggle to wake up.
