Meanwhile, FWIW, started monkeying with Siri Shortcuts. Now have voice transcription logger thingie, intending to keep a better daily journal. Now trying to figure out how to lash up Streaks.app reminders with Health.app's blood pressure data. (I know, I should just upgrade to a bluetooth enabled cuff. But I'm stubborn.)
I mention Shortcuts because I'm hoping it proves useful for the quantified self stuff.
