[Mac] Add a Mac app

I started building this purely as an iPhone app so that I could use Apple Health for storing Mindful Minutes. There are no analytics in the app to see how many people are using that feature, though.

  • With local storage in place, creating an Mac app would work, but it wouldn’t be able to update Apple Health on your iPhone, and there’s no Wind Down integration.
  • With iCloud syncing in place, updating Apple Health could happen on the iPhone.
