I found it useful to track “episodes of anger.” I’m not usually angry, so if I find myself enraged by something it is usually a good clue that something’s up. It is a nice clear signal, unlike a mood score.
I don’t find anger a problem worth tracking in my life but if I did I would probably be tracking it. I do track mood with the app “how are you feeling”
Good suggestion. I would probably add this in my misc field if I noticed it.
