This got me thinking, why don't I put my front-end web development skills to the test and build a tool that will help people optimize their sleep schedule?
So, I built a bedtime calculator with React JS, as well as some fancy CSS animations.
Looking forward to your feedback and suggestions :)
You've launched something and you've managed to get some very positive feedback. That's more than a lot of other people manage. Make sure you remember how good it feels, and use it as motivation to keep building and launching more projects. I hope we see more 'Show HN's from you.
I think the calculator itself isn't really useful, though I could be wrong. (The reason why I think it's not really useful is that I think the "90 minutes" cycles varies quite a lot between people, and the time between going to bed and to sleep can vary by half that length between people)
But what I really like, is that it is kinda (reasonably) click-baity, while it actually is a short, sourced, clean, no-ad, straight to the point, FAQ about sleep, which is useful to raise awareness of those issues.
