GutBrain is your 10-second poop tracker, stool log, and bowel movement diary for Irritable Bowel Syndrome (IBS), chronic constipation, diarrhea, bloating, trapped gas, and stomach pain. Log your daily poop with the Bristol Stool Scale, analyze meals with AI photo recognition and our Low-FODMAP food guide, and track probiotics, stress, sleep, and skin on one unified gut health calendar. Struggling with IBS flare-ups, chronic constipation, sudden diarrhea, bloating after meals, acid reflux (GERD), or irregular bowel movements? Digestion reacts to specific foods, FODMAP triggers, hydration, sleep, hormones, and stress. Keeping a daily poop log and food diary helps you spot recurring gut triggers and bring a clean PDF report to your gastroenterologist (GI doctor) or dietitian. ■ WHY USERS CHOOSE GUTBRAIN POOP TRACKER • 10-Second Poop Tracker & Stool Log: tap a Bristol Stool Scale type (Types 1–7) to log bowel movements instantly • Complete IBS Symptom Tracker & Food Diary: track constipation, diarrhea, bloating, gas, cramps, nausea, and reflux • AI Meal Photo Scanner & Low-FODMAP Diet Guide: spot triggers like dairy, lactose, wheat, gluten, garlic, and onion • New Gut & Brain Custom Diary: write daily gut reflections and customize your own daily check-in questions • Calendar Bowel Trend Graphs: visualize stool frequency, Bristol consistency, and symptom trends below your monthly calendar • Gastroenterologist PDF Reports & CSV Export: share structured bowel and meal histories at your next GI doctor visit ■ CORE FEATURES FOR DIGESTIVE & GUT HEALTH 1.
