## What is Nausea & Vomiting Tracker?

Nausea & Vomiting OS is a clinician-built logging app for chronic nausea and vomiting,
including cyclic vomiting syndrome (CVS) and cannabinoid hyperemesis syndrome (CHS).
Built by a practicing gastroenterologist, it captures the symptom
patterns and clinical anchors that make a gastroenterology visit useful.

What you log:
  • Nausea and vomiting episodes — frequency and duration
  • Cyclic pattern (CVS) and cannabinoid use (CHS)
  • Triggers and what brings relief (including hot-water bathing)
  • Hydration and weight

What you get:
  • A per-entry Assessment & Plan card that names the mechanism, not just the score
  • Episode burden 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 ACG-aligned nausea/vomiting evaluation, CVS guidance, and CHS
    recognition

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

About the developer:
  Nausea & Vomiting 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.
