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: • Today’s note: written from your answers, with a plan you can read line by line and the reason behind each line • Episode burden tracked over time • For your next visit: what you recorded and the questions worth asking your gastroenterologist, on one page • Premium: a one-page visit report for your doctor, symptom trends and CSV export • 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.
