Know your
gut.
Point your camera at a meal and get a straight answer — safe, moderate, or trigger — tuned to your gut, not a generic list.
A food isn’t “safe” or “unsafe.” It depends on you.
It's personal
Two people eat the same plate; only one reacts. Charts are averages — they were never about you.
It's the dose
A little garlic can be fine; a lot isn’t. We track the exact portion where a food tips into trouble.
It stacks
Small amounts across one meal add up. We total your load across all seven groups — not food by food.
It gets sharper every meal.
Most apps hand you the same chart on day one and day one-hundred. FODMAPSnap runs a loop — every meal you log teaches it more about the gut it’s actually working with.
Capture
Snap a photo, say it out loud, scan a barcode, or paste in a recipe.
Analyze
An instant FODMAP breakdown, food by food — with the portion where risk climbs.
Track
Log how you feel and when. Timing separates a real trigger from a coincidence.
Learn
Your seven-group profile updates — a little more confident every meal.
↻ then your next result is tuned to the profile you just sharpened.
Your sensitivity profile
7 groupsBars show confidence, not severity — they fill in as FODMAPSnap sees more of your meals.
Not a scanner. A daily tracker.
FODMAPSnap grew from a photo tool into the full system people with IBS and SIBO live in, day to day. Here’s what’s inside.
Log a meal any way
Photo, voice, a quick note, a barcode, or a saved favorite — whatever’s fastest in the moment.
A real daily timeline
Every meal on a chronological day view, with a calendar strip and a FODMAP exposure bar across all seven groups.
Servings that matter
Change the portion and the risk recalculates — half a serving and a double aren’t the same food.
Symptoms that teach
Eight types with onset timing. Feeling off but don’t know why? Log it and we backtrack the likely meal.
Beyond the plate
A daily check-in for mood, stress, and — if you want — your cycle. Your gut doesn’t only answer to food.
AI that connects the dots
Ask follow-ups on any meal, and get insights that surface stacking, timing, and emerging patterns over two weeks.
Recipes, safe for you
Browse low-FODMAP recipes or import any recipe from a link, photo, PDF, or text — with risk badges tuned to your profile.
Built for SIBO too
A dedicated diet mode with treatment phases and fermentation-aware warnings, layered on top of everything FODMAP.
English to Japanese, Korean, and Chinese — analysis and all.
