Celiac & Gluten Tracker

Track gluten exposures, symptoms, and serology with label literacy. Built by a gastroenterologist. 14-day free trial, then $8.99/mo or $59.99/yr.

Celiac OS is a clinician-built logging app for celiac disease. Built by a practicing gastroenterologist, it captures the symptom patterns and clinical anchors that make a gastroenterology visit useful.

What you log: • Gluten exposure events — intentional, accidental, and label-read • GI and extra-intestinal symptoms — fatigue, brain fog, skin • Serology results (tTG-IgA) over time • Follow-up anchors — DEXA and nutrient monitoring reminders

What you get: • A per-entry Assessment & Plan card that names the mechanism, not just the score • Symptom and exposure trends 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 on gluten-free label literacy, ACG-aligned celiac guidance, follow-up serology, and bone health

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: Celiac 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.
