What are you all tracking on a daily basis?

Trying to get a sense of what a daily routine looks like for people with EDS, as well as POTS or MCAS.

What apps are you all using, to track what specific symptoms, medications, food etc?

On a personal note, I am looking into creating an app that is specifically tailored for the EDS/trifecta, and I'd like to have a better sense of how good the current solutions are, and where they come short.
