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. It also attempts to contact facebook regularly even though I do not use it, do not have it installed and do not have an account connected to the app, which is odd.
The tracking is great, the charts are great, it does everything I like. But it's only getting 3 stars from me because it constantly shows 1mg, 5mg, et cetera from any drinks I had up to the past 2 to 4 days. So it skews the numbers because it's not properly zeroing out caffeine intake in a proper amount of time.
For a while, the size of the labels on the graphs was too small. That was my only complaint. Now that's fixed. It's worth paying for the full version. They have put together a good reliable app.
It's basic but does the job. The design of graphs is quite poor though
I've been using this for quite a while to monitor my caffeine levels seeing this is the only app I could find that would estimate the caffeine in my bloodstream. Always room for improvements.
Good tracker but it needs to zero out drinks faster and the graph needs to be scalable OR it needs to more clearly predict when you'll reach a desired caffeine level.
