I will put aside my anti-JavaScript zealotry and say this is good, nice, informative, etc. Couldn't be more simple to use.
jfax on HNGood work - no fluff, straight to the point. I got value out of this in under a minute.
Tade0 on HNThis is great. I've traditionally eye-balled it to be 90 min or 3hr cycles which works as a quick hack, but I'll consider this calculator next time. Can I just say, it looks like…
themacguffinman on HNBeautiful, really nice!

Wow! The site and its functionality are cool. I am not a web dev, so I can’t say much more than that. What really impresses me is the site’s collection of information and its…

Impressive for a 15-year-old

Great project! Happy to see young hackers at work. Doing things like this get you valuable experience, more useful to actually working than school.
mchusma on HNCool. I learnt some things. I don't care that you're 15, though.

Fixed 90-minute cycle is too simplistic; cycle length varies
From 3 comments
This is quite nice but I feel a bit too simple. Sleep cycles vary widely from 70-120 minutes per person. I think an advanced mode where a person can input their own record of…
191101 on HNThose calculations should be taken with a grain of salt: Sleep cycle length of 90 minutes is just a rough average. It varies throughout the night and gets affected by other…
blauditore on HNI thought sleep cycle length is variable to an extent. I once calculated my own to be around 110 minutes per cycle, rather than 90 minutes. Using that as a base for calculating…

Time display bugs: wrong times on Firefox Android, 12/24-hour inconsistency, clock off by an hour
From 3 comments
So I happened to open this site on Firefox on Android and it's giving me strange bed timings. For wake-up time at 6:00AM, it's showing me the following bed timings: 3:30PM,…
abhi_kr on HNThe site looks pretty nice. I have no experience in web design, so no real technical input from my side, but I noticed it is inconsistent with the time representation. You use…
gosslot on HNNice idea. The clocks are one hour off here: the text says 00:55 but the clock shows 11:55 pm, and so on.

Site appears to be affiliate or sponsored mattress marketing

If this is done by a fifteen year old, well done. Given the poor quality of so many web sites, well done regardless. And my apologies if I'm entirely off here, but given how…

Hnrobert42 on HNThis is really cool. My only critisism is based on the text below, i can't figure out if the times shown take into accound the 10-20 minuites to fall asleep, or if I should get…

Whether the maker built the wider sleepsources site
From 2 comments
Great work! I'm curious how this tool relates to the rest of the site: https://www.sleepsources.com Is it a family-run site that let you create and launch the calculator? Or did…
jasonlfunk on HNdid you make the mattress and bed frame site as well?

I've been using https://sleepyti.me for many years. It's simple and easy, which is usually good when I'm tired near bedtime. I actually like your time picker better, but…
