Reintro: FODMAP IBS Tracker

Reintro is a low FODMAP diet app for Phase 2, the reintroduction stage where most people stall. It schedules your FODMAP challenges, logs symptoms in seconds, and builds a tolerance map you can take to your dietitian. The elimination phase is simple to follow. Reintroduction is not: you have to remember which group comes next, step through small, medium and large doses, wait out the washout days, and still tell a real reaction from a bad night's sleep. Reintro handles that bookkeeping so you can focus on how you feel. WHAT IT DOES • Guided challenge schedule across nine FODMAP groups: lactose, fructose, sorbitol, mannitol, GOS, and the fructans in wheat, onion, garlic and fruit. Each group steps through small, medium and large doses, with a washout between groups. • A daily challenge card that shows today's dose, washout or rest day, with one tap to mark the dose done. • An IBS symptom tracker built for speed: severity sliders for the symptoms you chose and a Bristol stool picker. Most entries take about ten seconds. • Confounder logging for sleep, stress and your cycle, so a short night or a hard week is discounted instead of being blamed on a food. • A tolerance map that marks each group as tolerated, a trigger, or inconclusive, with the exact dose days and symptoms behind every verdict. • A missed dose does not wreck the plan. One tap adds an extra washout and moves the rest of the schedule forward. • A clinician PDF report with your schedule, outcomes, symptom trends and confounders, ready to share with your dietitian or doctor. • Re-test a food group three months later to see whether your food intolerance has changed. • Calm reminders: a morning dose, a check-in after it, and an evening wrap-up, capped at three a day with quiet hours. No streaks and no guilt. HOW IT WORKS 1. Pick your pace and the symptoms you want to track. 2. Follow the challenge card each day and log how you feel. 3. Watch the tolerance map fill in, then export the PDF before your next appointment. WHO IT IS FOR Reintro is for people with IBS who have finished the elimination phase, often with a dietitian, and want a clear answer to "which FODMAPs can I eat?" It is not a calorie counter, a barcode scanner or a recipe app. It is an IBS tracker and food diary shaped around one protocol, so the result at the end is something you can act on. PRIVATE BY DESIGN There is no account. Your food diary, symptoms and results stay on your phone and are never sent to us. The app contains no ads.
