How it works · Outgrit

The loop

Say it

Tap the orb and say what you ate, or how the session went. Or type it. Speech is recognised on the phone, and capture works with no signal.

Confirm

A model identifies the foods and the USDA table costs them. You see a draft, labelled AI, and nothing counts until you accept it. Your check-in is kept in your words.

Mirror

Sleep, heart-rate variability, resting heart rate and workouts are read from Apple Health. Read-only: Outgrit never writes to it.

Test

Once a week a statistics engine tests what you did against how your nights went. Only questions set in advance, at least eight days on each side, corrected for asking many at once.

Report

The sentences are written from the numbers, only about findings the statistics passed. Nothing can be added. “Nothing cleared the bar” is a real answer.

What a finding is

A number, how sure, and what it isn’t.

The effect, in real units.

Minutes of deep sleep, milliseconds of HRV. Never a score invented to sound precise.

How sure, stated.

Every finding carries its sample size and a confidence tier, and says what it does not show.

Observational, always.

“On the nights that followed…” is a description of your data. It is never an instruction.

Finding 01

Sample data

Late dinners × deep sleep.

▼29MIN

Moderate · n=20

Across 20 days, on the nights that followed a dinner after 21:00, deep sleep ran about 29 minutes shorter.

What this finding doesn’t mean

A pattern in your data, not a cause. Late dinners travel with late nights.

Observational, from your data — not medical advice. Correlation ≠ causation.

Outgrit shows statistical observations in your own logged data. It is not a medical device and provides no medical advice, diagnosis, or treatment. Lab values are shown with your lab’s own reference ranges — Outgrit never interprets them. Talk to a healthcare professional before changing diet, supplements, or training.
