EoE & Esophagitis Tracker

Track dysphagia, diet phases, and EREFS for eosinophilic esophagitis. Built by a gastroenterologist. 14-day free trial, then $8.99/mo or $59.99/yr.

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

What you log: • Dysphagia and food-impaction episodes • Symptoms by food texture • Diet phase — 6FED / 4FED elimination and reintroduction • EREFS and eosinophils-per-HPF from endoscopy/biopsy; dupilumab / PPI / swallowed steroid use

What you get: • A per-entry Assessment & Plan card that names the mechanism, not just the score • Symptom burden and EREFS 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 AGA/ACG EoE guidance, dietary elimination, dupilumab, and surveillance

Privacy by design: • All data stays on your device. No accounts. No cloud sync. • No analytics. No ads. No data sale.

About the developer: EoE 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.
