Most symptom trackers are built for someone with energy. They want numbers every day, scores out of ten, a streak to protect — and on the week you most need a record, they are the first thing to go.
taluvu is built the other way round. A check-in is a few taps and it is finished. There is nothing to lose by missing a day, nothing to catch up on, and no chart demanding to be fed. What you write is yours, in your own words, and it stays on your phone.
