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: • Today’s note: written from your answers, with a plan you can read line by line and the reason behind each line • HBI / SCCAI activity tracked over time • For your next visit: what you recorded and the questions worth asking your gastroenterologist, on one page • Premium: a one-page visit report for your doctor, symptom trends and CSV export • 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. • 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.
