Gutli: Program screen

A meal, symptom and low-FODMAP protocol journal for iPhone: log meals and check-ins, follow elimination and reintroduction, and bring a clear report to your clinician.

What Gutli does.

Records and patterns, not a diagnosis.

Gutli: Program screen

  1. Elimination, reintroduction and maintenance, with transitions you control.

  2. Meals, symptoms and reintroduction on one timeline and a calendar.

  3. Save meals and recipes you eat often, and find foods in the library.

  4. Meals and symptoms never go to iCloud; an exported backup moves them to a new iPhone.

How Gutli works.

Gutli makes the daily part of a low-FODMAP protocol quick: log what you ate and how you felt, move through elimination and reintroduction when you decide to, and see patterns with their confidence. It records; it does not diagnose.

  1. Log

    Meals with portions

    Time, ingredients, grams, notes and an optional photo, with a low/moderate/high portion reference.

  2. Check in

    How you feel

    Pain, bloating, nausea, energy and bowel check-ins with the Bristol Stool Chart.

  3. Reintroduce

    One group at a time

    Record food, dose, duration and response for each FODMAP group.

  4. Report

    For your appointment

    Weekly and monthly summaries and a clinician-ready PDF or CSV.
