IBS Symptom Tracker & Diary

IBS OS is a clinician-built logging app for irritable bowel syndrome. Built by a practicing gastroenterologist, it captures the symptom patterns and clinical anchors that make a gastroenterology visit useful. What you log: • Bristol stool form, bowel frequency, and urgency • Abdominal pain, bloating, and evacuation quality • IBS subtype (IBS-C / IBS-D / mixed) and symptom location • Optional voice logging — describe your day, on-device What you get: • A per-entry Assessment & Plan card that names the mechanism, not just the score • An IBS-SSS severity score tracked over time • A Visit Prep view that surfaces the questions worth asking your gastroenterologist • A clinician-ready export PDF — bring it to clinic or share via secure messaging • A library of ACG/AGA-aligned references on low-FODMAP, fiber, and IBS management Privacy by design: • All data stays on your device. No accounts. No cloud sync. • Voice logging (optional) is transcribed and extracted entirely on-device. • No analytics. No ads. No data sale. About the developer: IBS OS is built by a board-certified gastroenterologist. The app is decision-support — it does not diagnose, treat, or replace clinical care. Bring your data to your gastroenterologist. Subscription: 14-day free trial, then $8.99/month or $59.99/year. Subscriptions auto-renew; cancel anytime in App Store settings.
