GapReintro: FODMAP Reintro

Finished the low-FODMAP elimination phase? Reintroduction is where most people get lost. GapReintro gives you a clear, one-subgroup-at-a-time schedule, logs your symptoms in seconds, and builds a personal tolerance map you can take to your dietitian. It's a scheduler and a symptom diary, not a food database. Keep using whatever food guide or app you already use to look foods up. GapReintro handles the part those apps leave to spreadsheets and paper diaries. HOW IT WORKS • Pick a FODMAP subgroup: fructose, lactose, sorbitol, mannitol, GOS, or fructans split three ways (grains, onion & garlic, fruit) • Get a 3-day challenge with increasing portions, then a washout (3 days by default, change it per challenge) • One challenge at a time, so results don't get mixed up • Each subgroup comes with one single-FODMAP food suggestion and Day 1/2/3 portions as a starting point. Change the food to whatever your dietitian recommends. LOG IN SECONDS • Symptom type, severity slider, Bristol stool scale and a note • Log a reaction hours later and attach it to the right day. Logging happens during a challenge, so every symptom counts toward a result • Daily check-in for sleep, stress, menstrual cycle and anything else that could explain a symptom, so a bad night isn't mistaken for a food reaction • Missed a dose or had a flare? Insert an extra washout day and the rest of the schedule moves for you YOUR TOLERANCE MAP • Each subgroup shows Tolerated, Reacted, Inconclusive or In progress • The result is a suggestion from what you logged. You always have the final say and can set it yourself. WHAT'S FREE • The full challenge scheduler, logging and check-ins • Your tolerance map and current results • Dose and check-in reminders, with quiet hours • The last 30 days of challenge history • Backup and restore to a file you control • Dark and light themes, and text up to 200% GAPREINTRO PRO: ONE-TIME UNLOCK • Unlimited history across every past challenge • Re-challenge tracking: tolerance can change, so see every attempt at a subgroup • A clean PDF of your tolerance map and challenge log for your dietitian, plus CSV for spreadsheets One payment, never a subscription. Logging and your current results are never behind a paywall. PRIVATE BY DESIGN No account. No cloud. No ads. No analytics. GapReintro has no internet permission, so your diary stays on your phone unless you export or back it up yourself. IMPORTANT GapReintro is a scheduling and logging tool, not a medical device, and it doesn't give medical advice. The food suggestions and portions are general starting points from common reintroduction methods, not a personal plan. Do your reintroduction with a registered dietitian and check any result with them. Built by GapLogic, a two-person studio. Let's fix the gap in the app.
