About this app

GutNote is a private food, IBS and FODMAP symptom diary. Log meals, symptoms, stool (Bristol scale), stress and medication in seconds, then see the patterns a busy week hides — and walk into your next appointment with a clear PDF report for your doctor.

Whether you're managing IBS, bloating, acid reflux, a gluten or dairy sensitivity, or working through a low-FODMAP diet, GutNote helps you keep an honest daily record and spot possible food–symptom associations in your own data. Everything stays on your device by default, with optional backup when you want it.

WHY GUTNOTE
• Fast logging — add a meal, symptom, Bristol stool type, stress or medication in about two taps, including honest backdated entries with their own editable time
• Traffic-light calendar — see good and rough gut days at a glance
• Severity trend — track how your symptoms change over time
• Possible associations — an adjustable 1–72 hour time window surfaces the foods that tend to precede your recorded symptoms, with a confidence indicator, shown as possible associations, never as a diagnosis
• FODMAP tagging — flag high-FODMAP foods from a reference covering 115+ ingredients and dishes, translated into 7 languages
• Search & filter — find any past entry across your whole history, not just one day
• My Products — save your safe, recurring foods for one-tap logging
• Doctor-ready reports — export a clean PDF or CSV for any date range, including a custom range you pick, to share with your GP, gastroenterologist or dietitian

NEW: 3-PHASE LOW-FODMAP GUIDE
A guided walk through elimination, reintroduction by food group, and a personalization phase that builds a watch-list from foods you actually reacted to — based on your own logged data, not a generic article.

STAY ON TOP OF IT
• Live digestion-window notification right after you log a meal, with one tap back into symptom logging
• A private streak share-card that celebrates consistency without ever showing your symptoms, stool or medication
• Home-screen widget for one-tap logging
• Gentle, adaptive reminders based on your own logging patterns

BACK UP YOUR DATA
Export your full log — entries and My Products — as a backup file and restore it any time, so switching phones never means losing your FODMAP and IBS history.

100% PRIVATE BY DEFAULT
Your gut health data stays on your device unless you choose to back it up. No account required, no ads, no tracking. The PDF report is created on your device and shared only when you choose.

MORE
• Intermittent-fasting timer
• Dark mode
• Available in 7 languages

FREE & PRO
Logging, search, My Products and reminders are free forever. Upgrade to GutNote Pro to unlock correlation analytics, the FODMAP guide and PDF/CSV export — as a monthly or yearly plan, or a one-time lifetime purchase.

A NOTE ON HEALTH
GutNote is a personal food and symptom journal to help you notice patterns in your own IBS/FODMAP data. It is not a medical or diagnostic tool and does not diagnose, treat, cure or prevent any disease or condition. Always consult a qualified healthcare professional about your symptoms.

Start your IBS and FODMAP diary today and turn scattered gut symptoms into a clear picture.

GutNote works as a food symptom diary, IBS diary and bloating tracker in one: log with the Bristol stool chart, keep an acid reflux tracker alongside your meals, and follow a low FODMAP plan without a separate app.
