GutLog: IBS & FODMAP Tracker
Find your IBS food triggers
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Stop guessing what sets off your gut. GutLog finds the foods that trigger your symptoms 6–48h later — privately, on your device, with no ads.
GutLog helps you find out what's actually triggering your IBS — without ads, without selling your data, and without spending another appointment guessing.
Most symptom trackers just store your data. GutLog analyzes it.
WHY GUTLOG IS DIFFERENT
• Lag-aware trigger detection — gut symptoms often show up 6–48 hours after a trigger food, not the same day. GutLog looks across that window to surface the foods that actually precede your flare-ups, not coincidences.
• Built around the real clinical workflow — Bristol Stool Scale logging, FODMAP tagging, and a guided low-FODMAP reintroduction program with a personal tolerance map.
• A doctor-ready PDF report in one tap — bring real data to your GP or dietitian instead of trying to remember.
• Private by design — everything stays on your device. No account. No tracking. No ads.
LOG IN SECONDS
Meals, symptoms (bloating, pain, cramping, gas, nausea, urgency and more), bowel movements on the Bristol scale, plus sleep, stress and other factors — in just a few taps.
SEE YOUR PATTERNS
Clear charts of symptom frequency and stool form over 7 or 30 days, so you can tell whether things are getting better or worse.
FIND YOUR TRIGGERS (PRO)
Lag-aware correlation ranks your likely trigger foods and breaks down how often low, moderate and high-FODMAP meals are followed by symptoms.
REINTRODUCE FODMAPS THE RIGHT WAY (PRO)
Run structured 3-day challenges one FODMAP group at a time and build a tolerance map of what you can eat again — the way a dietitian would guide you.
SHARE WITH YOUR CLINICIAN (PRO)
Export a clean PDF summary of your trends and suspected triggers for appointments.
FREE & PRO
Logging, history and basic insights are free forever. GutLog Pro unlocks trigger analysis, the reintroduction program, Apple Health sync and PDF reports. Choose monthly, yearly (with a free trial), or a one-time lifetime purchase — no surprises.
PRIVACY
GutLog has no accounts and no servers for your data. Your log lives on your device (and your iCloud backup, if you use it). We don't collect or sell anything.
GutLog is a tracking tool, not a medical device. It does not diagnose or treat any condition. Always consult a qualified clinician about your symptoms.
