Daily logging that turns into a doctor-ready PDF.
Gutleaf is the daily logger for anyone managing celiac disease — for yourself or someone you care for. Three taps for food, bathroom, and reactions, and one tap to hand your doctor exactly what they ask for.
Built by a celiac family, for everyone managing celiac.
$4.99 once. No subscription, no ads.
The problem
You're keeping the log in Apple Notes. Or on the back of a receipt. And the GI follow-up is Tuesday.
Almost everyone managing celiac ends up doing some version of the same thing: a paper notebook, a Notes file, a thread of texts to themselves. Then twenty minutes before the appointment, you're scrolling backward trying to reconstruct two months of bathroom trips and "was that the restaurant pasta or the airport pretzel?"
Gutleaf replaces the scramble. Log a little each day, and the app quietly assembles the structured history your GI specialist actually wants — Bristol-scale distribution, food-reaction correlations, weekly gluten-free adherence — into a one-tap PDF you bring to the visit.
What it does
Four things, done well.
Daily logging in seconds
Three tabs — food, bathroom, reactions. Built for quick, one-handed use whenever and wherever it happens.
Doctor-ready PDF, generated on your phone
Pick a date range. Get a clean PDF with a Bristol-scale stool distribution, food-reaction correlation table, and weekly gluten-free adherence confidence. Walk into the GI visit with the answers already on paper.
Reactions & the Bristol scale
Note symptoms and severity, and track bathroom trips on the Bristol Stool Scale (types 1–7) — the same scale clinicians use.
Backdate anything you missed
Forgot to log yesterday's dinner? Open the entry, change the timestamp, move on. No guilt, no streaks to break.
Privacy
Your log stays on your device.
Gutleaf is local-first. Every entry lives on your iPhone — there's no account to create and no server to sign in to. The app works completely offline.
We don't run a server. We don't operate a database with your name in it. There is no third-party analytics, no advertising SDK, no location tracking. If we disappeared tomorrow, your data would still be right there on your phone.

An honest note
What Gutleaf isn't.
Not a scanner.
You won't point your phone at a barcode and get a verdict. You log what was eaten.
Not medical advice.
Charts and PDFs are summaries of what you logged, not a diagnosis.
Not a replacement for your GI.
It's the notebook you bring to the visit. The specialist is still the specialist.
Gutleaf is a logging tool. For medical questions, talk to your care team.
