Show HN: Caff.ai a Caffeine Manager for better sleep and more energy 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 have your last cup of coffee and still be under your bedtime target at bedtime. This helps you stay maximally caffeinated while minimizing the negative effects. I have over 600 drinks in my drinks list, and I'd appreciate any feature suggestions or tangential app ideas as well. https://ift.tt/oAxdBzl January 15, 2023 at 10:30PM
