Flat-Price IBD Trigger Desk

The people who pay are adults living with Crohn's disease or ulcerative colitis - roughly 2.4 to 3.1 million in the US (CDC, snippet only, page 403s) - and the job is simple: find which foods push you into a flare and hand your gastroenterologist a page they can read. But the competition is brutal and honest: there are at least eight near-identical store apps, the most-reviewed one (Cara Care) has not been updated in about five years, and Fathom - built by a co-founder who had already sold a company - ran out of money and shut down within a year of launching (Fathom shutdown opened, citation 17; co-founder exit confirmed on the opened team page, citation 20). The claimed differentiators are weaker than the pitch implies: Clairop's opened site already advertises three delay windows out to three days, a one-page GI report and 'one subscription, everything included', and mySymptoms already runs correlation with variable reaction windows - so the only real openings I can defend are Android coverage (the newest dedicated apps are iPhone-only) and a single low flat annual price. One documented flaw is concrete: a FlareCare review shows a patient logging severe urgency for weeks while the app's own doctor report said 0%. The pitch is one flat $29 a year on both platforms, with the trigger analysis and GI report included and the log stored so it survives a broken phone; whether a flat $29 can be profitable is an untested hypothesis, not a proven one. Do not build yet: recruit 30 people from r/CrohnsDisease, r/IBD and flare-focused Facebook groups who paid for a tracker in the last year, show them a clickable demo of the trigger report, and ask for a $29 annual pre-order.
