## What is Fathom?

Bloating, irregular days, the "what set me off?" question… Fathom is a calm, private gut diary built to find the answer in your own logs.

LOG IN ~20 SECONDS
• Stool form on the Bristol scale, with a broad colour note
• Food diary — type what you ate and tag factors like dairy, gluten or caffeine
• Hydration, stress and sleep in one gentle daily check-in

GUT DETECTIVE: SPOTS THE PATTERNS FOR YOU
After 14 logged days, the Detective compares your own days and shows what lined up — like a food that appeared more often alongside softer days, or bloating that clustered around high-FODMAP meals. Always with the numbers behind it.

WHY FATHOM?
• No account, no cloud — your diary stays on your device
• No ads; a calm, 20-second flow
• Optional: fill a meal from a photo (the photo is never saved)
• A clean PDF summary you can share

Fathom is a wellness diary: it does not diagnose, detect or treat any condition, and it is not a substitute for professional medical advice.

## Version history (last 4 releases)

### 1.0.4 — 2026-07-28

A new look. Fathom now carries its own mark — a quieter, more considered icon — and the onboarding has been drawn from scratch: bespoke animated motifs, including one that actually shows how Gut Detective compares your own days. Logging stays free, always.

### 1.0.3 — 2026-07-22

A warm new setup that gets you going in under a minute — tell Fathom what you'd like to understand and it tailors what Gut Detective looks at first. Plus a clearer Premium screen with the free trial shown up front, and a small celebration for your first pattern. Logging stays free, always.

### 1.0.2 — 2026-07-15

New: optional meal-photo suggestions. Images are reduced, metadata is removed, and every food and tag stays editable. Plus clearer wording in all five languages.

### 1.0.1 — 2026-07-13

No release notes.
