FODMAP Detective

About this app

What FODMAP Detective does

FODMAP Detective is the offline guide through the hardest part of the low-FODMAP diet: the reintroduction phase, where most people get stuck and never learn which foods they can actually tolerate. The low-FODMAP diet is the first-line dietary treatment for IBS, which affects 25-45 million Americans. But the gold-standard food-rating app (Monash) has no symptom tracker, and the comprehensive logger (mySymptoms) produces analysis reports users call 'completely useless.' Nobody owns the guided-reintroduction-plus-readable-results niche. What FODMAP Detective does: — Guided challenges, one FODMAP group at a time. Fructose, lactose, sorbitol, mannitol, GOS, fructans — the app walks you through a structured challenge for each, with the right test foods and portions, and schedules the challenge and washout windows. — Symptom logging that fits IBS. Bloating, pain, urgency, stool (Bristol scale), gas — logged in seconds, time-stamped. — Per-group tolerance verdicts. After a challenge, FODMAP Detective gives a plain-English result: 'You tolerated lactose well' or 'Fructans triggered moderate symptoms at half a serving.' The correlation report Monash and mySymptoms never deliver. — Bundled FODMAP food list. Foods tagged by FODMAP group and serving threshold, on-device — no recipe or barcode API. — Challenge reminders. EventKit nudges for the next test dose and the washout day. — Doctor/dietitian PDF. Export your full reintroduction results. — No account, no ads, no subscription, no cloud. For the 25-45M Americans with IBS whose dietitian told them to do reintroduction — and who need a detective, not a spreadsheet.
