## What is GERD & Acid Reflux Tracker?

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

What you log:
  • Heartburn and regurgitation frequency and severity
  • Timing — with meals, at bedtime, and nocturnal symptoms
  • Triggers — foods, late meals, body position
  • PPI / H2-blocker use and symptom response (GERD-Q components)

What you get:
  • A per-entry Assessment & Plan card that names the mechanism, not just the score
  • A GERD-Q proxy score 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-aligned references on reflux management, PPI use and
    de-prescribing, lifestyle change, and alarm features

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:
  GERD 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.
