Statistics of Self-managed labels (mood, environment, etc.)
This is about the labels which can be selected wthin the notes-section (e.g. head ache, movie night, etc.). I think tracking of subjectively perceived health, mood and general circumstances is a very powerful tool if this feature is extended.
From my view, I see two major user stories for this topic.
As a user I want to have access to statistical data around my own labels together with food and activity data in order to be able to identify possible causes of, for example, food cravings, physical or mental malaise.
Please don't hesitate to contact me via e-mail in case you want more backgound info or need somebody to test.
