Why it feels different

A health journal with the soul of a food magazine.

Food confidence

Clear FODMAP status, serving context, and swaps — fast enough for the grocery aisle.

Low-friction tracking

Log meals and symptoms in seconds, with recents, duplicates, and one-tap severity.

Pattern discovery

Likely correlations surfaced gently — never dressed up as diagnosis.

Editorial delight

Premium photography, weeknight recipes, and a warm, unhurried tone of voice.

Personal safety

Plain-language disclaimers, privacy-first storage, and respectful reminders.

The food guide

Fast answers, honest language.

Search knows your shorthand — exact names, common aliases, and the foods you reach for most. Each food page reads like a well-edited entry, not a database row.

  • A portion ladder, because tolerance is rarely all-or-nothing.
  • Humble serving notes — “often tolerated in small serves,” never “safe.”
  • Suggested swaps when a favourite lands in the high column.
  • Source & review dates visible on every rating.
“Unknown” is an honest answer too — the guide never dead-ends you on a food it hasn’t reviewed.

The daily journal

A log you’ll actually keep.

Most daily entries take less than a minute: recents resurface first, yesterday’s lunch duplicates in a tap, and symptoms record on a single 0–10 slide with context that matters.

Insights

Patterns, spoken carefully.

Insights use pattern language, never diagnosis. Better Belly tells you what appears in your data, how confident it is given how much you’ve logged, and what might be worth raising with your dietitian.

“appears near” “often follows” “worth discussing”
  • Weekly recap — logs, symptoms, most-logged foods, best-tolerated meals.
  • Confidence indicators that grow with your data, not ahead of it.
  • Correlation ≠ causation, stated plainly wherever patterns appear.

  • Private by defaultHealth-adjacent data is never shared with advertising services.
  • Export anytimeTake a clean copy of your journal to any appointment.
  • Honest framingA plain-language disclaimer appears before you ever start tracking.
