I downloaded an app that I think is meant to be used for like, detailed food tracking or something, but I instead really just wanted something with this format (color coded calendar days) so I could put in one single simple entry a day to kind of rate my day overall (based on physical health symptoms).. which..... looking back over it for the new year since when I first started tracking.. 9 "good" days in about 9 months, so roughly one good day a month LOL...
