Functional Dyspepsia Tracker
Indigestion & bloating diary
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Track your meals, pain, and fullness in real time. Bring a clear symptom record to your gastroenterology appointment.
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.
