Functional Dyspepsia Tracker

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

What you log:
  • Postprandial fullness and early satiety
  • Epigastric pain and burning
  • Symptom pattern — postprandial distress (PDS) vs epigastric pain (EPS), Rome IV
  • Meal relation and symptom severity

What you get:
  • A per-entry Assessment & Plan card that names the mechanism, not just the score
  • PDS / EPS pattern and severity 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 Rome IV functional dyspepsia, neuromodulators, prokinetics, and
    H. pylori test-and-treat

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:
  Functional Dyspepsia 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.
