Customer Reviews

So useful!

I track my caffeine intake daily and being able to model for the next 24 hours is great!

Please add an export capability. I have a sleep quality database and I want to be able to match these 2. Integrating data with Apple Health would also be nice.

Working again, almost

At least it launches and doesn't crash..
First data entered appears on graph, later entries show up in history but graph didn't change. Starting over.

Not very well designed

The interface is cumbersome, the graph is trivial, and notifications are conflicting.
