Caffeine Clock – A beautiful and accurate caffeine tracker app

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…
