Caffeine App - Track Caffeine 4+

This app really helps me make sure I can fall asleep easily at bedtime. I like the ability to customize the target amount of caffeine per day, at bedtime, and adjust bedtime. I find it to be an accurate predictor of how long it will take me to fall asleep.
There is one minor bug in the latest version: when logging a new amount the “sleep ready” time shows the current time. It used to correctly show the time I’d be ready for sleep if I took that amount of caffeine, which was helpful in deciding what to consume.
And there are some quirks, like when you add a new custom amount you can’t rename it until after adding it. And newly added custom amounts appear at the very bottom of the list instead of the top. But for an ad-free app it’s great!

I was looking for an easy way to better track my caffeine just to be more mindful of my consumption & have it sync to the Health app. This does just that & I love it so far. I love how I can add my own drinks I commonly use as well as being able to quick add using force touch. The “ready to sleep” might be iffy for me. I know it more than likely uses the overall half-life of caffeine, but I wish it would also factor in weight with the metabolism. Other than that, I am loving how easy it is to use & trackZ

This app does a pretty good job tracking caffeine intake in its many forms. I like the graph showing how it slowly dissipates from your system. Americans should note that many of its preloaded caffeine types are products and stores found in Germany since the developer is presumably German. It’s nice that you can add your own categories and forms of caffeine. I added dark chocolate to my list of groups.

The app could be improved by allowing users to set physical characteristics that determine caffeine affects each user according to body weight, or other factors.
