App is rudimentary to say the least. Graph could be scalable with more detail, any point should be selectable to display caffeine level and time at that point. I need more precision, this app does not provide it. If I was not so busy I would have refunded it. I cannot even see the end of the graph, where caffeine reaches 0. Would be nice to have a configurable widget as well.
Overall the app is fantastic. I love that you can customize your drinks, that you can set your own personal goals, and that it helps you predict caffeine levels after so long. My only issue is I want to try to export the data and, no matter where I export the data to, it won't work because the data file is empty. Perfect 5 if I can get help on that.
Fantastic app. What it does that the others don't - and what makes it worth the price - is that it shows you how long the caffeine you drink now will be in your body. Setting how much of my morning coffee was still affecting me at midnight or 4am was a real eye-opener. Also I saw that I didn't need as much as I thought because a lot is still active in the afternoon. I dramatically cut back my caffeine in just two weeks with this app. Highly recommended.
As a fitness professional, I very much approve and appreciate this product. It helps me keep track of my caffeine intake, as well as clients that download it.
Really like this app, especially the graphical presentation of the caffeine level. Would be even better with more accurate figures of how much is in each drink. Overall excellent app
Some pie chart issues, but mostly ok
* Fixed bug exporting data in later versions of Android
