Fathom: AI Gut Diary

Patterns, never diagnoses. Log your gut in 20 calm seconds — your diary stays on your device and insights come from your own data.

Fathom is a calm, private diary for your digestion — designed to feel less like a medical form and more like a moment of quiet attention.

LOG IN ~20 SECONDS • Stool form on the Bristol scale, with a broad colour note • Meals — type what you ate and tag what you want to watch • Hydration, stress and sleep in one gentle daily check-in

MEET GUT DETECTIVE After a couple of weeks, Gut Detective points out associations in your own logs — like a food that more often lined up with softer days. Always with the numbers. Always "worth a look". Never a verdict.

PRIVATE BY ARCHITECTURE • No account or cloud sync; your diary stays on your device • Optional meal photos are reduced, stripped of metadata, and never saved by Fathom • Export everything, or delete everything, with one tap

A REPORT YOUR DOCTOR WILL ACTUALLY USE Turn your logs into a clean, honest PDF summary — Bristol distribution, symptom trends, and your self-tracked associations, clearly labelled as observations, not findings.

Fathom does not diagnose, detect or treat any condition, and it is not a substitute for professional medical advice. If something concerns you, Fathom's calm education points you to a clinician — never to a verdict.
