My biggest help with pacing: The app Visible. It is mostly but not always congruent with my self-assessment. So when I feel bad I ignore it and rest, if I feel good I have a look if it warns me and heed the warning. Works great.

Yeah, I really like the symptom and exertion tracking! I used to use the notes to indicate if it was rainy, too, since that has an effect on me, but I'm thinking i should make it a custom on/off toggle.
