I m Cyril, a solo founder building Dosion, a local-first iOS supplement tracker.
My first vibecode project was BioAionics. I made a lot of mistakes, burned money on tokens, rebuilt things more than once, and eventually landed on Dosion.
It s for people who actually take supplements: schedule, take/skip/miss, nutrients, Apple Health, offline, no ads, data stays on the phone. Not another cloud wellness app.
