About this app

Gutstep is a low-FODMAP diet tracker for people with IBS who are working through elimination and reintroduction with a dietitian. It helps you find out which FODMAP groups you react to, one step at a time.

THREE PHASES, ONE CLEAR NEXT STEP
Start with elimination (usually 2–6 weeks). Then reintroduce one group at a time: Fructose, Lactose, Fructans, GOS, Sorbitol and Mannitol. Each challenge runs over 3 days with a small, medium and large amount, followed by a 2–3 day washout. Your home screen always shows the phase, the day and what today's amount is.

LOG IN SECONDS, EVEN ON A BAD DAY
Four buttons at the bottom of the screen: Meal, Symptoms, Stool and Day. Rate abdominal pain, bloating, gas and one symptom of your own on a 0–10 tap scale, record stool type on the Bristol scale (1–7), and note stress and sleep.

SEE HOW EACH GROUP WENT
After Day 3 of each challenge, mark it Tolerated, Partly tolerated or Trigger based on what you logged, next to the symptoms from each challenge day.

A REPORT FOR YOUR DIETITIAN
Export a concise PDF report with your phases, challenge results and symptom history, ready to share or print before your appointment.

YOUR DATA STAYS ON YOUR PHONE
No account and no sign-in. Your log is stored on your device.
