   Caffeine Clock – A beautiful and accurate caffeine tracker app▲14

   Hi guys! I would love to show you Caffeine Clock 2.0, a tracker I made that shows you your caffeine levels now and in the future, helping you have undisrupted sleep by timing your caffeine better. A bit of context - as a guy who drinks a lot of caffeine, I wanted to make a good caffeine tracking app for a long time, since nothing I found at the time was sufficient. I wanted to make an app that would be easy to use, show you exactly when you’d have enough caffeine to not have your sleep disrupted, and could add all the drinks I usually drink, for free. After several iterations, I am now…

   Caff.ai a Caffeine Manager for better sleep and more energy▲6

   Hey HN, I often don't know if I can have a coffee at 2pm and started logging my caffeine intake so I wouldn't be up until 2am. For me it was never as easy as a cut off time (ie stop coffee at 1pm) because I vary the amount and timing of my coffee day to day. I made an app that helps you stay in your custom 'daytime target range' and under your 'bedtime target' caffeine level. It can predict how much caffeine you'll have at bedtime and tell you what time your caffeine will be below a configurable sleepable level. I also added a feature that gives you a notification 30 minutes before you can…

    Prevent your computer sleeping with just a webpage▲252

    There's often times I want to prevent a computer/laptop/VM from sleeping and while, yes, there's various Caffeine/Amphetamine apps they're often overkill. Instead, this small (12Kb) page does the job and only needs a web browser. It's just a very simple usage of a web api normally used for things like video players: https://developer.mozilla.org/en-US/docs/Web/API/Screen_Wake...
