Notice the pattern in your gut.
A private diary for meals, bloating and IBS symptoms. Spot possible food associations over time and export a clean, doctor-ready report.
Flare-ups feel random. They usually aren't.
Paper diaries fall behind, notes apps turn into chaos, and by your appointment you can't remember what you ate last Tuesday. The pattern is in there — it just needs a calmer place to live.
Paper diaries fail
They're easy to forget and impossible to search when a bad week finally arrives.
Mystery flare-ups
Was it the coffee, the stress, or last night's pasta? Memory alone can't tell you.
The appointment gap
Ten minutes with your GP is no time to reconstruct three months of meals from memory.
Logged in seconds, so you actually keep it up.
Four things, four quick taps: a meal, a symptom, the Bristol scale, and how stressed the day felt. No essays, no friction — the kind of diary you keep for months, not days.
A clinical scale your doctor already speaks.
Tap a type from 1 to 7 on the standard Bristol stool chart, add a 1–5 severity, and GutNote records it in plain clinical language — the same vocabulary your GP uses.
A month of your gut, at a glance.
Every day becomes a soft coloured cell — calm green, cautious amber, difficult red. Clusters of hard days jump out instantly, so you can see whether last week was really as bad as it felt.
Possible food associations — as ratios, never guesses.
Symptoms can lag a food by hours. Slide the window from 1 to 72 hours and GutNote counts how often each food happened to precede a symptom in your own log. It surfaces patterns to discuss — it never claims a cause.
- Adjustable 1–72 hour look-back
- Shown as plain counts and ratios
- Ranked by how often, not by certainty
These bars show how often a symptom happened to follow a food inside your chosen window. They are observations, not conclusions — widen or narrow the window to explore possible associations.
Educational FODMAP tags on everyday foods.
Common foods carry a gentle high / low FODMAP label so you can learn the landscape as you log. It's background reading, not a prescription — always pair it with professional guidance.
Typically low FODMAP
