About Sleep Cycle

Sleep Cycle is a simple time calculator that makes it easy to manage sleep cycles, so that you wake up well-rested. The calculations are based on findings from scientific studies that show the human brain sleeps in cycles of approximately 90 minutes, with the end of each cycle being the best time to wake up well-rested.

Sleep Cycle works in three modes:

- Fixed Wake-up: Allows you to set your desired time to wake up, and suggests the optimal times to go to sleep based on your selection.

- Fixed Bedtime: Similar to above, but instead specifying the time you're going to bed, listing the optimal times to wake up.

- Sleep Now: When you're feeling tired and want to go to bed right away, this mode will display the best times to set your alarm clock to, based on your device's current time.

All three modes can automatically configure your Android alarm clock to the selected time.

I've used this app for a long time and it's always woken me up, to be honest I've only ever used the fixed wake-up time section of the app. However, I have realised that there is no way to view or delete an alarm you have set. Does anyone know how to do this? The reason I ask is I randomly woke up at 3am thinking I hadn't set an alarm, momentarily forgetting that I didn't have work that day. So I set the alarm to my usual 5:20 time, but now I can't find a way to cancel it. The only thing I think I can do it set a sleep now alarm for long after I when I want to get up, and hope it cancels out the first one?! Anyone got any suggestions?

Better rating if the spelling error of "Fuxed" was changed to "Fixed" and if menu also showed actual Sleep Cycle count next to each time. It still has best combination of features when I compare it to several other similar apps. Many other similar apps do not have all three modes of Fixed Sleep Time, Fixed Wake Up Time and Sleep Now. Before you criticize this app, learn the purpose of it as explained by this Google Store page and also try other similar apps which are less feature complete. This app has greatly helped me adjust to my ever changing work schedule as long as I am careful to always sleep in the cycles suggested and never cheat or snooze!

It didn't really work out for me at all and I barely used it for like 5 minutes and the whole app was really blank and lame.

The best part of the app is it gives me the option to wake to a tone of my choosing and not one the android developers have decided was usable to me.Many of which are too low to hear with a running semi. Otherwise, the only complaint I have is... where I am shows snow... i'm in 70° weather. I think the term... snowballs chance in hell is appropriate.

Not sure if there is more to this app. Other than the intrusive ads it seems pretty useless. I would pay for premium but I don't think it is worth it.

I thought this app would show me my sleeping pattern through the night, but it only says when to wake up based on when you fall asleep? Confusing app as well with some possible redundancies

All I'm getting is ads. I am going to uninstall. Maybe with directions it would work.

Is used the app to see what time I could get up and not be tired....and it worked! I woke up not tired for once. I use it when I have to get about 3-4 hours sleep because of my busy schedule and see what time I should go to sleep to not wake up tired.

Simple app that only calculates when you want to sleep or when you should wake up based on your sleep cycles. Exactly what I was looking for.

Literally all that this does is tell me when i should sleep. App is pointless
