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:
