Need to let us show time caffeine taken as an option instead of how long ago. Also could use interface improvements

Great. Does exactly as you'd expect. However, it would be nice to be able to view farther back into the projection chart history.

Just what I was looking for, but there is definitely room for improvement.

Quite useful. Great app. Tgree features that would be appreciated. 1. The ability to schedule a cup of coffee in the future to see what the long term decay will be. 2. Citation of the formula used to calculate caffeine decay and how much this might vary from person to person. 3. Upgrade the chart view to be more easily readable.

Needs a number of feature improvements, but nothing fundamentally wrong I am left disappointed with this app because there are a number of features that are broken or missing. You need to add an option for am/pm instead of 24hr for time entry. I should be allowed to enter in a drink at a future time, say if I'm going to drink 1 hr from now and I wanted to compare the effects of a coffee vs a soda. There is also no option to indicate rate of drinking. Whether I chug my coffee or sip it over an hour, the app has no way of distinguishing. Thus the graph will always look the same - a cycle of spiking and decaying. Graph: The numbers on the X and Y axes are so small that you have to squint to read them. You must add the ability to zoom in/out if nothing else. The notifications need to be overhauled. There should be more granular options, say If I want to be notified ONLY when I go below the minimum threshold. Right now it's just "all notifications on" vs "all notifications off" which isn't very helpful. Not a bad start but I really hope you take this feedback seriously and integrate it in future updates.
