Do you ever find yourself waking up feeling cranky even though you had a decent amount of sleep?

Or have you taken a nap and felt great one time yet felt horrible another time?

The reason for such scenarios is that you most likely woke up in the middle of one of your sleeping cycles.

Sleeping works in cycles of 90 minutes. That is why you might get a good amount of sleep yet still feel tired (because you most likely woke up in the middle of one of your sleep cycle).

With 90night (a sleep cycle calculator inspired by the popular website sleepyti.me [Sleepytime, Sleepy time]), you can calculate the times you can wake up if you know when you are going to sleep or you can calculate the times you can go to sleep if you know when you are waking up. It also provides you buttons you can press that can set an alarm for you using your preferred alarm app.

Features that 90night includes:
[✔]The ability to set how long it takes you to fall asleep and 90night will use that time in its calculations
[✔]Support for both 12/24 hour format (with the ability to change them)
[✔]A night mode for using a dark theme for the app to avoid straining your eyes in the dark
[✔]Buttons to set alarms for each time (with optional confirm dialog box which can be turned on in settings
[✔]The option to automatically add extra snooze alarms after you set the original alarm (with the option to pick how many alarms you want and the interval between the alarms)
[✔]NEW: Dashclock extension to show you your sleep times right from your lock screen!

What's different in Plus version:
[✔]No advertisements!
[✔]Ability to use shortcuts without sharing the app
[✔]Extra features coming soon!

Permissions Explained:
• Network communications: Used for ads
• Alarm: For setting your alarm

FAQ:
Q: Why doesn't 90night have an option to delete alarms?
A: Because as the developer, I am not given permission or the ability (through the API) to go inside alarm apps and delete alarms. There are a few alarm applications out there (such as Circle Alarm) that automatically remove alarms after they have gone off.

If you have any questions, requests, bugs/issues, or features you want, feel free to email me.

    The only problem I have is when I add a alarm to wake up. I cannot remove it. So I have a list of alarms on my alarm clock app.

    I'm sure this is a wonderful app, however the first time I set it, it said I have 10 alarms already. How is this so? I just downloaded it a few secs ago. This app is useless to me. Get this figured out, and it will be awesome.
