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.

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

Looks good.

Any chance of an option for 24h mode?

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.

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.

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

ksauceyt t1_jcmqiqc wrote

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

Noice.

If only it could account for random 30-120 of tossing and turning trying to fall asleep...

I’m not finding this easily in the App Store…should I be able to download and install this like any other iPhone app? I’d like to put it next to my Clock / Alarm app so that I can meaningfully set bed/sleep/wake timings

Appreciate the effort but this is already a small function of the fully fleahed out alarm app "sleep as android" that I use

It's not in the app store (yet!), but you can add it to your home screen next to your Clock/Alarm, just like an App Store app.

Open the site in Safari on your iPhone (sleepy.im), then hit your share button on Safari's menu (aka the square with an upwards arrow). You should then have an option to "Add to Home Screen". You can make the name shorter if you like, then tap to Add the icon to your home screen and move it around like any other app.

Hope that helps!

That's a good shout! You're right, it's currently working on a rough average of 15 mins to fall asleep, so I'll make that clear and look at making it a setting so different folks can adjust as necessary.

u/Ryuzzaki it doesn’t appear to work on iPhone 12 Pro Max, iOS 14.1 using Safari or Chrome unfortunately. Aside from updating (which I won’t be doing on this device), any ideas on how to get it working?

Purely technical: Your site presents the "time to sleep" in the client's locale ("9 heures of sleep") but still shows the wake up time as AM/PM.

It would be nice if the wake up time followed the 12h/24h setting of the locale.

Ryuzzaki OP t1_jcn55g1 wrote

Replying to Indrigis (#2,258,842)

Yeah, definitely some improvement I can make here. I'll add proper 24 hour support and pull it from the locale + make it user selectable. Thanks for the feedback!

Former sleepytime user as well, definitely bummed when that changed. I don't remember them having the option of 'i know when I'll fall asleep...' so thank you for including that in your version!

Thanks, I used sleepyti.me a ton when I was in school and working full time, I noticed it got weird later on and I was dissapointed. These things are so useful when you need to basically minmax your sleep

Sleep as Android(app, not a typo) is basically this. Uses phone sensors to measure your movement and determines sleep phase on that. You can set it to have a wake-up window as well, to target that easily waked state. At least, it worked well for me.

I’ve also used Sleep Cycle for several years and love the feature that wakes you up in a 30 minute window of time. It tries to pick the best time to sound the alarm, when you’re not in that deep sleep. You can change the window of time but I think 30 is the recommended time frame.

Aw, that sucks about Sleepytime. I stopped using it a while ago but have actually been thinking of using it again after getting on meds for my fatigue.

Thanks for this. I'll have to look into it.

Fun fact, the shorthand (sic) is used to mean (I know you might think I made a mistake, but I'm accurately recreating the thing I'm referring to). Like if a court document references a Tweet that has a typo/misspelling or if a proper noun is stylized in a nonstandard way (like in your example), you could insert "(sic)" without quotations to signify to the reader that the "mistakes" were written with intention.

You didn't say anything incorrect, but thought you might find this interesting enough to spend 97 words to help you save 3 sometime in the future.

Sorry to be that guy, but that's not how sleep works and your calculations are off and not usefull. It's better than not caring about sleep at all of course, and might help somebody who simply just doesn't sleep enough, so it's good you made it anyway.

For anyone having sleep issues, please read Why we sleep if you consider your problems mild, or visit sleep centre or consult your doctor if it's affecting your day-to-day functioning.

procrastinator_prime t1_jcos1bg wrote

I think there is some inconsistency. If I select I want to sleep at 10 pm (It says fall asleep at 10 pm once I click calculate), wake up time suggested is 05:45 am. If I select I want to wake up at 05:30 am, It suggests falling asleep at 10 pm.

At the very least, you need to have one of these as go to bed, and the other one as fall asleep.

Rather than reading an entire book to understand your views, can you summarize things?

I would assume you are referring to variability in sleep patterns, but I don't know for sure since you just said, read a book. I think that's a big ask.

Why isn't there any app directly on my Samsung watch that automaticaly wakes me up when i finish my 12 cycles ?

iamjkdn t1_jcq0evg wrote

Tell me this, is it bad to sleep more than 6 cycles? I tend to wake up late but sleep early. Maybe 10-11 hrs of sleep. Sure you might have researched on sleep a lot to build this, what are your thoughts on sleeping more than 9 hrs based on your research?

I've heard the placebo argument but I find it a bit questionable. On occasion my brother who has downs has trouble sleeping and we give him it and it works really well. He has no idea what he's taking or why, so in that case it seems effective.

aeon3k t1_jcspnx5 wrote

The app is nice and simple. Maybe add translations for other people but it’s just that…

I just don’t believe in alarm clock anymore. I have noted throughout my life that when I go to bed at the right time, if I eat and exercise correctly and I’m not stressed out, I fall asleep when I need to and wake up naturally refreshed when I need too. When I’m filled with purpose and goals I even get up earlier !

We should ditch sofisticated mechanisms and try to find out what works for us. I’ve given you my recipe and it works better than anything else.

So now you are comparing yourself to someone that has a complete different body and strange genetics?

Also, are you sure he doesn't know and or want to see results?

Because the only recent study is a meta study that asks for a good trial since it may help, nothing concrete.

https://pubmed.ncbi.nlm.nih.gov/28648359/

As I said, 99.99 % 9f the supplements give more melatonin than the liver can remove in 24 hours, thus destroying your melatonin cycle and even making sleeping worse.

From all the people I know that used it(myself included) with or without works the same.
