01 How it works

Three steps. Ninety seconds. Real signal.

Step 01

Download the free app

iPhone or Android. No account, no card, no commitment. Open it and you're recording in a minute.

Step 02

Place phone on abdomen

Lie down, set your phone face-up on your stomach, tap record. The microphone does the rest for 90 seconds.

Step 03

See your pattern

A gut-brain snapshot scored across four dimensions, with plain-language notes — not a chart you need a degree to read.

02 If you've ever

Done everything — and still felt guessing.

You've tried the probiotics. The elimination diet. The supplements your friend swore by. Your doctor said "manage your stress" and handed you a brochure. None of it told you what was actually happening in there.

— 01
You've eliminated foods one at a time and still can't pin the trigger.
— 02
A "good gut day" and a "rough one" feel different but look the same on paper.
— 03
You're tracking symptoms in three different apps and none of them notice your stress.
— 04
The next appointment is months away. You'd like something to look at before then.
03 What you get

Your first recording is your baseline.

One picture. Four signals. Plain language.

Most apps log how you feel. NeuroGut AI records what's happening — a measured snapshot of gut activity paired with heart rhythm and breathing.

Years of guessing. This was the first time I could actually see something line up with how a meal felt. It's like having a baseline for the first time.

My doctor kept telling me to "manage stress" without ever showing me what stress was doing. I finally have something to look at between appointments.

Ninety seconds. That's the part that surprised me. I didn't have to wear anything, I didn't have to journal for a week. It just… recorded.
