90night: SleepyTime Calculator

90night: SleepyTime Calculator


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.
Q: Why is the app called 90night?
A: It's actually a play on words! A sleep cycle is 90 minutes long and sleeping happens at night and when the name of 90night [90 night, ninety night] is read out loud it sounds like "nighty night!"

Very functional. Not pretty. This app has great functionality. The custom wakeup time home screen shortcuts are a great feature. But the whole app could really use a facelift. Dated look that doesn't inspire sleep.

Sadly, No The app bases what time you go to bed on what time you should wake up in the morning, or vice-versa...if you need to wake up at a certain time, then you should plan on going to bed at a certain time to get the recommended hours of sleep. It also accounts for how long it takes you to fall asleep. Twenty minutes beforehand, I entered 22:10 as my bedtime, so that it would wake me at 06:10. I was jolted awake by the alarm at precisely 22:10, which was the time I calculated I should be asleep. I was irked, as I have trouble falling asleep anyways, and just as I had dozed off, the app wakes me up. I tapped the "Dismiss" button and fell back asleep. 8 minutes later the alarm woke me up again, despite the fact I had dismissed it earlier. I slammed my finger on the dismiss button again and fell back asleep.The alarm woke me up early this morning and I felt quite tired and this time, hit the snooze button. It went off again 8 minutes later like it was supposed to. However, the time read 03:10, 3 hours before it was supposed to wake me. I reset the alarm to 06:10. It then woke me up at 05:47. I give up. I am sleepy and foggy-headed today.

I don't wake up tired nor grumpy anymore with this. I would like the timer to have an "advanced" mode to where the preset 15-20 minute sleep time expectancy could be changed
