Lots of apps, and lots of smartwatches, have that, yep :)

Sleep as Android is my go to app for that

Thank you! Sometimes I have very late school nights and end up staying awake until like 4 in the morning. Ive always wondered if it was better to go to bed or just stay awake at that point and this answered my question with those shorter times with only one or two cycles. Great site, bookmarking it for sure

Are there any devices which somehow detect where you are in a sleep cycle and not alarm at the wrong time? I have a flexi schedule, so something like that would work

I'd mention something about estimated times to fall asleep. It usually takes me about 30 to fall asleep, I know a lot of people do it in 15, and some almost instantly. At least if I know what you are assuming (it looks like 15?), I can easily adjust. Also the style is great, it looks awesome and I love how easy to use it is.

Man I've been doing this for a while. I hear that 4.5 hours, 6 hours, or 7.5 hours are the best lengths of sleep to aim for. If I know I can't get the full 6, which is usually what I aim for, I can manage the 4.5hr cycle a few days out of the week and still truck along without much issue, especially if the day before wasn't very taxing.

This is amazing

I recommend body scan meditation. 10 minutes and I am so relaxed I fall asleep. There are plenty of guided meditations on YouTuber, Spotify etc.

Looks good.

Any chance of an option for 24h mode?

cute owl 😀

The problem for me is falling asleep at the right time :D

Nice! I had noticed sleepytime has changed a bit, I don't use it super often, but I'll have to change my bookmark.

Nice.Thanks for that

Will give it a try. Thank you!

Didn't work

Hey folks!

I put together this minimal sleep calculator app after the one I was using (sleepyti.me) was bought out and turned into a giant ad.

If you've never used a sleep (cycle) calculator before, the idea is that sleep is cyclical, with the body going through lighter and deeper phases in roughly 90 minute cycles. This app suggests times to go to bed or to set your alarm, aiming to wake you up in a lighter sleep phase.

It's not quite an exact science, but I find it helpful (as someone who is more of a night owl than a morning person).

Appreciate any feedback and hopefully some of you find it useful!

Update (22/03): Thanks for all the feedback all! As per requests, the site now has a 24 hour mode for those of you who prefer it (toggle between 12/24 in the settings menu, cog icon on the top right). Also resolved some issues a few people were seeing on older browsers.

They've got both the ancient hindu, buddhist or whatever swastika as well as the really shitty one on there too. Probably could just omit that

Pretty cool ♬
