You know something's wrong. You just can't see the shape of it yet.

You're standing over the sink again, running through everything your kid ate today. The pizza at the party? The yogurt this morning? You don't know. Neither do they. They just want the cramping to stop.

Your pediatrician said to keep a food diary. Easy enough for three days. By week three, exhausted, you can't remember if the bad night came after the strawberries or the week before that. So you guess. You cut dairy, things seem better, you're not sure if that's real or hope. You put it back. Right where you started, still wondering if you're the one missing something obvious.

BellyMystery won't tell you what's wrong. It remembers what you can't, so next time you're in that office, you're not saying "it happens sometimes." You're the parent who showed up with the evidence.

How it works

Four steps. You don't have to remember any of it yourself, that's the whole point.

Log the moment

Snap a photo of what they ate, in under 30 seconds, and BellyMystery reads off the ingredients for you. No typing. Tag a stomachache or a stool on the Bristol scale in under 15 seconds, one-handed if you need to, while you're comforting a kid who feels lousy.

Spot the pattern

Every meal you've logged gets checked against every symptom and stool that followed it, right there on your phone. No cloud database, no spreadsheet, no trying to hold three weeks of dinners in your head.

Read it in plain English

When something stands out, like reactions after 6 of the last 9 dairy meals, BellyMystery says so in plain language, not a wall of numbers. It never tells you what your kid has. It shows you what's worth asking about next.

DONE

Bring it to the doctor

Export a PDF with the pattern summary and the full text diary (photos left out), so next time you're not saying "it happens sometimes." Hand it to a pediatrician, dietitian, or anyone else helping you figure this out.

This is the whole thing, start to finish.

One tap to log a meal or a stool, and it's already working toward the report you'll hand your doctor. Swipe through to see exactly what that looks like.

BellyMystery home screen showing three logging options: meal, toilet event, and symptom — **Pick what to log.** One tap for a meal, a stool, or a symptom.

Meal logging screen: typing 'Cheeseburger' with AI-suggested ingredients like beef, cheese, and bread shown as removable tags — **Type or photograph a meal.** AI suggests ingredients, you confirm.

Stool logging screen showing the seven-point Bristol scale as tappable illustrated tiles — **Tap a Bristol scale tile.** No scrolling, no typing.

BellyMystery diary screen listing chronological meal and stool entries with times and ingredient counts — **Every entry, chronological.** Nothing gets lost between visits.

Analysis screen reading 'Dairy exposure may correlate with reactions' with supporting counts and a plain-language explanation — **Get a plain-language pattern.** Framed for a doctor discussion, never a diagnosis.

No extra time. No extra worry.

Seconds, not minutes

Meals, symptoms, and stools take seconds, not minutes, even at midnight with a kid who just wants to go back to sleep.

Private by design

No account, no login, nothing to set up while you're already stretched thin. Your family's diary stays on your device. Only a meal photo and a computed summary of patterns are ever sent off it, and neither is stored afterward.

Pay once, keep it

One payment unlocks BellyMystery for as long as you're figuring this out. No subscription, nothing recurring, nothing to remember to cancel.
