I couldn’t find a Habit tracking app that I liked. They are all so needy, with bad UIs, poor data visualisation, and ill-suited to my use case.

I want to track frequency of both positive and negative events, then see their distribution and correlations.

I figured out a way to do this natively on #iOS by using the HealthApp in a slightly unintended way: define the things you want to track as Medicines!
