Unsibo - SIBO Daily Guide
A daily companion for people managing SIBO. It rates 350+ foods, keeps the meal-spacing rhythm visible, and exports a journal a gastroenterologist can actually read. Designed and built solo for iPhone and Android.
The Challenge
For a condition this common, SIBO is strangely invisible. Irritable bowel syndrome affects roughly 1 in 10 people worldwide, and a large share of those cases may be small intestinal bacterial overgrowth carrying the IBS label. Yet the people living it are often told it is in their head, sent home from 15-minute appointments with vague advice, and left to manage with the same calorie counters and streak trackers as everyone else. The shelves were full of static FODMAP lists and generic symptom diaries. Nothing was built for the SIBO day to day.
The Approach
SIBO does not fit in a food diary. It runs on meal spacing, the 4 to 5 hour rhythm a calorie app quietly works against. Its diet is a 3-phase path where most people give up at Reintroduction, the exact moment a fixed list stops helping. And its symptoms feel random until enough days line up to show the pattern. I built Unsibo to do the thing no generic tracker does: surface the foods and habits behind a flare, and give people a way to manage their day around them.
The app is 4 surfaces a person can face on a bad day. A countdown ring keeps the meal rhythm visible without alarms or streak pressure. A food guide rates 350+ foods by FODMAP load and learns each person's own tolerance as they log, with a custom icon for every food, 356 in all. A timeline reads those logs back as plain-language triggers, the kind that finally connect an afternoon flare to what was on the plate at lunch. 6 guides go deeper: Elimination, Reintroduction, Personalization, Low Fermentation, Gut-Brain Toolkit, and Your Type Track. On top of those sit a library of voice-guided exercises and recipes built around SIBO-safe ingredients. And a one-tap export, My Digestive Journal, hands a gastroenterologist months of real history to work from.
The Outcome
Unsibo is live on iPhone and Android, designed and built solo, end to end. React Native and Expo on the app, a Next.js marketing site with a public food database, Supabase behind both, and an AI layer that turns a person's own logs into plain-language trigger summaries. The bet behind it is simple: the first companion built specifically for the SIBO journey, aimed at a market the size of a major chronic condition that every existing app had quietly walked past.
