IBD Tracker: Crohn's & Colitis

IBD OS is a clinician-built logging app for inflammatory bowel disease — Crohn's disease and ulcerative colitis. Built by a practicing gastroenterologist, it captures the symptom patterns and clinical anchors that make a gastroenterology visit useful. What you log: • Stool frequency, rectal bleeding, urgency, and abdominal pain • HBI (Crohn's) and SCCAI (ulcerative colitis) component scores • Extra-intestinal symptoms — joints, skin, eyes • Biologic / medication doses and fecal calprotectin results What you get: • A per-entry Assessment & Plan card that names the mechanism, not just the score • HBI / SCCAI activity 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 biologics, steroid-sparing strategy, and calprotectin monitoring 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: IBD 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.
