MyTummyHurts puts every food you eat on trial — with your own calm and rough days as the evidence — and hands down verdicts you can trust. Including the one no other gut app gives: cleared.
Case closed — in their favor
Repeated rough days behind it. It really is them.
Something rough on the record. Under review.
On the board — no evidence either way yet.
Calm so far, nothing against it.
Repeated calm, zero rough. Officially exonerated.
The case file
No elimination spreadsheets, no 40-question quizzes. Two small habits — the app does the detective work in between.
Point the camera at the plate — or the menu. Every ingredient becomes a suspect, tracked from that moment on.
Calm, rough, or somewhere in between. Five seconds. Your days are the only testimony that counts.
Not vibes, not streaks — distinct days, counted honestly. Every verdict shows its count, so you always see why.
Caprese for lunch. You scan it — tomatoes go on the board. watching
One-tap check-in: calm. First calm day on the record. calm 1 of 1
Pasta pomodoro, normal portion. Calm again. calm 2 of 2
Two more tomato days. Zero rough ones. calm 4 of 4
Calm on 4 of 4 days you ate it — cleared.
The verdict no one else gives
Every other gut app ends the same way: a longer list of things to avoid. This one runs the other direction. Eat a food calmly enough times — zero rough days — and its case closes in its favor. Officially cleared, confetti and all.
“You can stop worrying about tomatoes.”
Not a smaller life. A shorter fear list.
Cleared: Tomatoes
Calm on 4 of 4 days you ate it
Back on the menuThe honesty policy
Gut advice is drowning in fake certainty. This app is built to say “probably,” “unclear,” and “here's the source” — and to be checkable when it does make a call.
A scan read lands in an honest band — mild, moderate, high, severe — because that's what the evidence supports. No fake-precise 63.7s.
A dark photo of a mystery stew doesn't get a confident score. It gets an honest couldn't read this — never a guess dressed up as one.
Reads cite real research — Monash University FODMAP data, NIDDK guidance — and a citation only appears when it's actually about what's in front of you.
The app checks its own predictions against how your days actually went. When it called a meal risky, did the rough day follow? That number exists — and it keeps us honest.
Your conditions decide what the app watches first. Portions count — a bite of cheese isn't a cheese board. And the only thing allowed to move a verdict is your own calm and rough days. Not a generic trigger list. Not other people's stomachs.
It even notices your day adding up
“Second dairy-heavy meal today — effects stack.”
Your partner on the case
Pip is the little stomach who runs the board — files your scans, logs your check‑ins, and takes every cleared verdict personally.






Gentle, a little wry — and not once has Pip guilt-tripped anyone about the fries.
