Meet Koji

Understand your bloating
with just a picture

Koji connects what you eat, your cycle, and how you feel. Snap your plate — and start seeing what triggers what.

Paris·IBS & bloating·Cycle + gut

They found their trigger

The first journal that actually sticks.

Léa

In three weeks, I figured out it was legumes. Three years of looking.

Maya

I bloated most before my period. Now I can actually see it.

Chloé

The morning reminder takes ten seconds. It’s the first journal I’ve actually stuck with.

The gap

Digestive apps ignore your cycle. Cycle apps ignore your gut.

Koji crosses both. In three weeks, you’ll know what triggers what.

Snap your plate

One photo. The tags fill in.

Photograph your plate. Koji recognizes the dish, suggests tags — gluten, dairy, legumes — and you correct with a tap. Then you say how your belly felt.

Three journals

Twenty seconds. Never a blank page.

In the morning, how you feel. After a meal, what you ate. Transit, when it happens. Checkboxes — not a notebook you drop after three days.

Period
Follicular
Ovulation
Luteal

Cycle + gut

Your gut follows your cycle.

In the luteal phase, progesterone slows your transit. Bloating, constipation, sensitivity: that isn’t random. Koji lays your symptoms over your phases.

Insights

First patterns around week three.

Koji crosses the food, the delay, and your phase. You finally see why you bloat after some meals — and not others.

All in one app

A quiet journal. Clear patterns.

Not a diagnosis. A method for reading your body.

Plate photo

You snap, Koji suggests the tags. You correct if needed.

Morning journal

Belly at wake-up, energy, mood, sleep — in a few taps.

Meal & feeling

What you ate, and how your belly responded.

Transit

Bristol type, comfort, in twenty seconds.

Cycle

Your phases, overlaid on your journals — only if you want.

Insights

Triggers, correlations, a file for your doctor.

How it works

Three gestures. Koji does the math.

01

You photograph

Your plate, or you pick the tags yourself. Twenty seconds.

02

You log how it felt

Morning, after a meal, at transit. Boxes, not a novel.

03

Koji crosses

Food, delay, phase. First patterns show up around three weeks.

Questions

What Koji is — and isn’t.

No. Koji is a personal journal. It doesn’t diagnose, doesn’t prescribe, and doesn’t replace medical advice.

Privacy

Your gut stays yours.

Your journals, plate photos, and cycle data are only used to give you insights in the app. They are never used to train an AI, sold, or shared for advertising. Edited from Paris.
