Your nervous system, in real time

Your body knows
before your mind does.

Momomoon detects rising stress through biometric signals — and intervenes with a 1–2 minute haptic reset, before stress compounds.

The problem

Most tools show you data about the past.

By then, it’s already cost you.

The system

Detect. Interpret. Intervene.

Detect

Multi-signal physiology, not guesswork.

HRV. Heart rate. Sleep. Motion. Temperature. Continuous, in the background, no input required.

Interpret

Cross-referenced with your real day.

Your calendar, your routines, your learned patterns. The same spike means different things at 9 AM and 4 PM.

Intervene

A 1–2 minute haptic reset on your wrist.

A subtle vibration. Not an alarm. Triggered the moment your nervous system shifts — or by you, anytime.

Momo — text and voice

Not a chatbot. Not a voice assistant.

A conversation grounded in your signals.

Momo reads your biometrics, your calendar, and your patterns — and talks about your day, not generic stress advice. In text at your desk. In voice on the walk. And when your body shifts hard enough, on the line — calling you.

Lenses

Each Lens, a different way of seeing yourself.

Lenses are premium, clinical-grade readings — paired with a Momo reading, so the result is a conversation, not a verdict. The Drawing is Lens 01, live now: a drawing-based reading built on a method clinicians have used since 1948. CBT-grounded Lenses are next.

See what your day actually felt like.

In 5-minute resolution, mapped to the meetings that shaped it. Not a dashboard. A read.

A stylized preview of the iOS Emotional Timeline.

Your data

Your biometric data is yours.

We don’t sell it. We don’t share it.
The Apple Watch processes most of it on-device.
We treat your nervous system the way it deserves to be treated — privately.

The founders

We engineered Momomoon for ourselves first.

We’re software engineers — Wenwen at Amazon, Mahmud at Meta — building this in the hours after our day jobs. Trackers told us we were stressed. They didn’t catch it. So we built the system that does.
