Sleep Cycles provides an interface to find the perfect time to fall asleep or wake up. It utilizes researched methods to decide the optimal time to setup alarms.

By using the proper sleep cycle at night, you will feel more refreshed when you wake up. Your body is typically already in a half awake state during a REM cycle. This application just calculates when these typically occur!

You can decide when to fall asleep, based on a wakeup time specified by you. Assuming your phone has the ability, it can also setup alarms to remind you to start heading to sleep and one to wake up.

You can tell it you're heading to sleep now, and it will assume you need ~15 minutes to goto sleep. It will list the best times for you to wake up, and also provides the ability to set alarms for any of these times.

This works for me, I just needed it Androidized.

Whats new

    Version 4 removed ads. Version 3 crash was due to ads being removed.
    Version 5 will include a built-in alarm. I am currently in the process of creating and testing this alarm. This should help the Galaxy S2 users who cannot access their alarm in Android 2.2, 2.3, and 4.0.3.

Life Changer This app has literally changed my life! I used to wake up sleepy and/ or late almost everyday. I thought I needed more sleep but it was just impractical for me to go to bed that early. With sleep cycles, I go to bed at a reasonable time and wake up refreshed. I get to work on time and I feel great! The UI is not that attractive & I wish I could choose the alarm. That's why I gave it 4 stars instead of 5.

Only one glitch More advanced, accelerometer-based, apps don't work for me as I don't sleep alone. So this app is a gift from above. I get off work late and have to get up early, so being able to look at four different "wake up times" and picking the one that best fits my schedule as I plug the phone and put it on my nightstand is a blessing because I just CAN'T have a steady bedtime. Then during the weekend I have the luxury of picking the most cycles so I don't get that "I overslept because it's the weekend and now I feel like I got run over by a truck" feeling. Seems to work well on my HTC EVO 4G. The only glitch is that one simply cannot use the default clock for the alarms. Bad things happen. The default alarm clock sucks anyway, just use it with a BETTER alarm, right now it seems to play nicely with Alarm Clock Plus. I just worry that it keeps adding new alarms.

Works better than expected I was skeptical at the concept, but it really seems to work. Have woken up fresh quite a few times now. Great app

A Google User

Well done. I have so many ideas for this maturing program... This along with Sleep Droid can really do wonders.

A Google User

Ok app. Pretty much just a calculator. Forces close when I try to set the alarm feature. It calculates when I need to get up and I set my own alarm

A Google User

Perfect Adds alarms to your phones alarm. Go to your alarm settings to change the alarm to whatever ring tone you want and disable the time to sleep alarms

For one day.... The app worked great the first time I used it, and I woke up refreshed. Tried to set it tonight, but the wake up times never changed, no matter what time I set for when I was going to bed. Removing app, can't have something working only when it wants

Good info, not functional It's good for getting a decent time to sleep but whenever I tap on a time to set the alarm, the app crashes. HTC Desire

James McMeeking

Unpredictable at best After using the " going to sleep now" button and selecting what time I should wake up, it sometimes works perfectly, but sometimes adds 12 hours to my alarm time. I can't see any kind of pattern and it's quite frustrating to wake up late, then have an alarm go off that evening telling you to wake up...

Awesome. So easy. Simple. Doesn't have all the unnecessary fluff that others do. Keeping it simple.

A Google User

Simple and works I was looking for an application to calculate the sleep cycles, and I found tons with a lot of features but not the basic one, this fill exactly what I wanted, thanks

Mark Mwangi

Awesome Didn't know bout sleep cycles till I bumped into an article on the web. This app has been indispensable since.

George G

Good but no perfect This appis great calculating time to sleep and wake up .it is connected with alarm clocks on your phone to set the alarm. The only con i can see is in the want to sleep now mode, which also needs a nap function and not only 8 hours sleep.

Miranda Mckinnon

Love it. Does the math for you, but let's you change it if you want.

Tyler Kushma

No military time Simply put there is no military time opition for me to set. Other than that this app is great to do the quick math about when I should go to sleep even though I'm an idiot and never do so anyways

Crashes with inspire Clock does not work with the inspire and forces to close!!!!

A Google User

Great Would be even better if we could set the 'fall asleep' time.

Maia niemen

Never stops Even when I shut my alarm down it somehow just does it again the next day and waking me up a 5 on a sat.

A Google User

Good app but ad icon appeared on my home screen!!!! The cheek of it!!

Alarming This is an alarm that wakes you up and tells you how long you slept. Nothing i didnt already know

Jeremy Cotton

Usually works I've been using this for about a year. I work nights and its helpful in picking a good time to wake up so I won't be groggy and be able to do daytime things. Sometimes though it adds 12 hours to the alarm so if it's 5am it will set the alarm for 1250 19 hours later instead of 7...

Useful app Hope new version won't interfere with standard alarms.

Bader G. AlShammari

Great app Easy and simple,, looking for Holo UI to be awesome.

Kyle G

Fantastic This app is simple to use and extremely efficient. It may not work for everyone, but for it works great. Just remember to turn of the vibration if you're not a fan of it in the mornings.

Fouad Al-Amri

It's good It's working very good for me ..thanks

Jason Chapman

Alarm setting issue It suggested the right time, but it set the alarm for midnight instead of noon.

Aleksandra Petrov

Best app Does what it's supposed to do. Simple and accurate.

Roy Velasco

Good Job Very nice & simple application, does not invade your ptivacy & does not drain your power. it simply does what it said :-)

A Google User

Good app Does what is says. 5 stars

jessi burden

. It doesn't work 4 me

A Google User

Seems to work well enough. The sleep cycles are just based on averages rather than collect any data about the user. It would also be great if I could tell it how long I think it will take me to fall asleep rather than it just assume 15 minutes. I've been using it with Gentle Alarm and the two work very well together.

Sam Crowe

Helps me know when I must sleep

A Google User

Can't use it. I have an HTC Inspire Android and everytime click a button in the app it crashes and force me to close.

Rasta Magda

Was Looking 4 this one :-)sleep tight :-)

A Google User

Unsure... It is good BUT, can't get it to set wake up alarm as promised...

Hayani Ishan
