A Gut DayA Gut Day
About us

Built by people who live with sensitive bellies.

A Gut Day exists because we got tired of guessing. Tired of forgotten food diaries, tired of generic FODMAP advice, tired of arriving at appointments with vague memories instead of real data.

Our story

We started A Gut Day after years of personal trial and error with IBS, lactose issues and unexplained flares. The tools we needed didn't exist - the closest was Excel. So we built the calm, modern gut journal we wished we'd had: fast to use, smart enough to find patterns, and respectful of how vulnerable gut data really is.

How A Gut Day helps

Our roadmap is shaped by gut-focused dietitians and people with IBS, IBD and intolerances.

Independent, by choice

No insurer ownership, no advertising. Funded by users on Premium.

What we believe

  1. 1

    Your data is yours

    Always. We never sell, share or train external AI on it.

  2. 2

    Calm beats clever

    Tools should reduce anxiety, not add to it. Soft palettes, kind language.

  3. 3

    Patterns over panic

    We rank correlations from your data - never make scary claims.

  4. 4

    Dietitians stay central

    We make their work easier, not redundant. Treatment is theirs.
