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.

Have tried several different apps for sleep cycle. Simple, easy to use, no annoying ads that keep popping up. It's just want I needed.

I've used this countless times. Excellent interface and works! I've never woken and been too sleepy to function normally when using this!

it's amazing

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!

Useless!!!Thumps down😬

that's what it said no instructions

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.

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

Per. T. Sep 18, 2016     

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 love this app. I've been an insomniac my whole life and just to complicate things I'm also nocturnal. I guess there's truth to sleep cycles cuz I wake up every time feeling great

Mo. H. Mar 29, 2016     

Went through 5 ads before i could click. Uninstalled before i could even try to use it.

Ana. K. Mar 26, 2016     

I already have my favorite alarm app, so this is sleep cycle app that i need. Simple and accurate.

Sam. C. Jul 7, 2016     

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

Smart. Just takes a little training in the body!

Tells you nothing..

Sta. V. Jan 26, 2016     

It actually works very well and does exactly what it's made for. Interface is also very neat and clean.

Mic. M. Feb 16, 2016     

Love it

Ala. F. Jan 9, 2016     

I love the last update it has made the app more efficient yet very simple to use.

Jol. C. Sep 20, 2015     

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.

Chr. T. Nov 4, 2015     

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.

Jos. B. Oct 18, 2015     

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

Za. Z. Sep 19, 2015     

Just started using and in two minutes doing settings two pop up ads. Ugh.

Him. H. Nov 11, 2015     

Who would want such a horrible thing

Dav. G. Jul 29, 2015     

They need it to be a pop up

Ash. Q. K. Dec 21, 2015     

Told me nothing.

Always

Cha. K. Aug 21, 2014     

I don't always get the recommended 6-8 hours. Before, I would go to sleep and get as much as I could and end up feeling groggy and exhausted. Now with this app I'm able to determine the best time to get up based on how many hours I can get. I get up feeling refreshed even when I get less sleep.

Ada. W. Jan 7, 2015     

Simple app, focused more on waking you up after cycles of 1.5 hours. Too many advertisements, makes the app rather difficult to use.

Cap. D. Mar 23, 2015     

Waking up refreshed is great (especially with my insomnia).
