Sleep Calculator
This is a free sleep app that can set an alarm for you to wake up in-between sleep cycles in order to start the day relaxed and with a clear mind.
Every time you go to sleep, you experience a series of sleep cycles that last on average 90 minutes, and waking up during one of the sleep cycles makes you feel groggy and exhausted even with plenty of hours of sleep
- sleep cycle calculator tries to determine the best wake up times, or go to bed time in order to workaround this situation.
Perfect at figuring out sleep cycles and recommended for people who have trouble sleeping and don't have a fixed sleeping schedule.
There are four sleep calculation scenarios to choose from:Scenario 1: you want to know when to go to sleep in order to wake up at a specified time. Sets a go to bed alarm.Scenario 2: you want to know when to wake up if you go to bed at a specific time. Sets a wake up alarm. Scenario 3: you want to know the best times to wake up if you go to sleep right now.Scenario 4: you plan to take a power nap and you want to know when you should wake up.

Wanted to install on my new phone and the previous one but still not available ("not compatible" message in playstore), hope you'll get it back on devs. See I do like the app (would be 5*) and use it also on my new phones but only because I made and have a APK backup devs. It does still run up till Oreo now. Come on get it fixed and back on Playstore (minus 1*).
Great little app and really has helped me figure out when to wake up and when to go to bed. Not sure why caller ID was added to the app but it's a bit silly that people leaving 1 star feedback because of it, by default it's not turned on under permissions so it can't actually do anything unless you allow it to.
Recent update added caller ID function is useless and irrelevant for the app. All those adds after every call is stupid. I am deleting the app
Had this on my S6 and now that I updated to S7edge, it's incompatible? Help me please, this is a simple straight to the point app that I use and love. I've tired to replace it with other apps, but the ad pop ups are so annoying and frustrating! Will change to 5 stars if someone can help
I simply cannot understand the use of the caller ID function?? Someone please explain to my how that is useful, or in anyway related to a sleep calculator! If I wanted a sleep calculator, I will download a sleep calculator, If I want a caller ID function I will download a caller ID app. I understand that I can turn it off at anytime, but why would you defend a feature that has directly led to so many people uninstalling your app and downloaded a hassle free alternative?
Features I downloaded it for are great, but it's getting one star as long as it has the extra annoying junk...
Hey this is a good app , don't ruin it by adding caller ID , I use Truecaller for that . Make another app for caller ID .
It helps me decide the best time I should wake up
Mysterious totally unrelated to calculation caller id function recently added. Nope nope nope. Uninstalled.
Recently added useless caller id filled with adds, what's next? You're going to ask me to do my banking through your sleep calculator? Uninstalled, worked great before, so this is sad
Without caller ID it's a 4
It does the basic thing i want it to do and it does it well.
Uninstalled because of random caller id bloatware.
I have to uninstall because of Caller ID
very helpful and simple to use!!
I download a simple calculator got a caller ID full of ads really ?? Uninstalled
It works!
Sleep cycle app has been great. Adding unnecessary features nothing to do with sleeping is pointless. Please put into a separate app rather than in this.
Bloatware. 5 stars to no stars. Anyway, I can just calculate my own sleep cycle and activate my own alarm.
If I download a sleep calculator, its because I want just a sleep calculator, is this so difficult to understand? Please create stand alone apps for whatever experiments you want to try... Thanks
A Caller ID feature? You already have an dedicated app called 'Call Blocker' where this feature is present. Please don't start adding unrelated features, you're already getting 1 star reviews because of it. Consider removing it to keep this app small, clean and simple.
This used to be a best in class app. Why add caller id notification??? How is that related to sleep patterns??? Sorry, uninstalling.
This app used to connect with the sleep cycle app to set an alarm. Why doesn't it do that anymore??
Great app, what's with caller id?
Good basis to work off. Great selection of options, makes it easy and faster to set alarms. My cycle can fluctuate so I set alarms at intervals over 30 mins (15 minutes either side of advised time), each gets a bit louder and I always wake up when I'm ready at the end of my cycle. 30 minute naps never a good idea for me.. 10, 20 or a full cycle
I definitely wake up easier using this app. My favorite thing about it is the different calculators. Some nights I go straight to bed and use the "when do I wake up if I got to bed now" calculation, but other nights I want to watch an episode of TV before going to sleep so I use the "I want to sleep at the following time" calculator. It's awesome!
I honestly doubted if the app will help me, but it for sure does help!! It helps me to coup with reduced sleep time easily, also the option to set the amount you take to sleep is really helpful as that can change a lot for me depending on how exhausted I am. Anyway it's a great app and thanks to the developer for a simple yet helpful app.
Would love this app, but the alarms it sets have no sound. The alarms I set manually do have sound, I have also set alarm volume to max. At first I thought I was dismissing them while sleeping, but today I accidentally woke up and realised the alarm on the screen with no sound. 5 days in a row I woke up in the afternoon instead of morning because of this. :/
I love this app, and sad that it may have been discontinued. I love the simplicity of the interface with the scenarios. This is the only app that has a power nap feature of 20 and 30 mins. Please bring it back, I would also love to have this on Apple App Store.
