Sort of useful, but the interface drags it down I like the tracking features and half life graph. But, this is 2015 and the app's interface is obnoxious and confusing. Google has some clear guides for app interface that would really improve the workflow and make finding functions easier.
Works great! I find that when I can feel my levels dropping, I have a notification from the app within +/- 15 minutes that I'm below 200. I wish there was an option to have a gradual decrease over a few months so you can reduce/eliminate caffine intake.
Not enough options. Green tea and black tea have different caffeine content.
Good, but would be nice to have more options. There is no option to add pure caffeine such as is in pre-workout. Please add.
Awesome Very accurate and useful app that seems to adopt a proper exponential model of caffeine metabolism. Awidget would make it perfect.
So so...not w worth money Never removes the final 2mg of my diet coke. Statistically questionable.
Bug fix: Fix issue with inaccurate level on refresh when preference options "Using birth control" or "Pregnant" were selected.
