About Stooly - AI Poop & Gut Tracker
Your gut health speaks volumes. Stooly makes it effortless to listen. Snap a photo. In seconds, Stooly's AI analyzes your stool — shape, consistency, color — and translates it into a clear gut health score. No manual logging. No expensive devices. No subscriptions. Just open the app, take a photo, and understand your digestion. Stooly is 100% free with no ads. Your gut health shouldn't cost $400 or come with a monthly fee. HOW IT WORKS Open Stooly → Take a photo → Get instant AI analysis → See your gut health score → Track changes over time. AI STOOL ANALYSIS Stooly uses computer vision grounded in the Bristol Stool Scale — the same clinical framework gastroenterologists use — to evaluate stool form, consistency, and color automatically. No buttons to press, no scales to select, no forms to fill out. One photo gives you a complete analysis. TRACK PATTERNS OVER TIME A single reading is interesting. A trend is powerful. Stooly helps you: - See how your gut health score changes across days, weeks, and months - Spot shifts in stool consistency or appearance before they become problems - Connect what you eat and how you live to how your gut responds - Identify patterns you'd never catch on your own CLEAR INSIGHTS, NOT MEDICAL JARGON Stooly turns complex digestive signals into plain-language explanations anyone can understand. Visual summaries, trend charts, and simple scores — designed so you actually learn something about your body every time you open the app. PRIVACY IS NOT OPTIONAL This is the most personal health data imaginable. Stooly is built to protect it completely. - Photos are analyzed instantly and discarded immediately — never stored - Your data is never sold to anyone, period - Built from day one with privacy-first architecture You own your data. Full stop. NO HARDWARE. NO FEES. JUST YOUR PHONE. Smart toilet sensors can cost hundreds of dollars and require installation. Subscriptions add up month after month. Stooly delivers AI-powered gut health tracking with nothing but the phone already in your pocket. It's free today and it stays free. BUILT ON CLINICAL SCIENCE Stooly's analysis is grounded in established clinical research and the Bristol Stool Scale — the standardized classification system used by healthcare professionals worldwide. This is real digestive health awareness backed by science, not a novelty app. Share your Stooly data with your doctor to make appointments more productive. Bring actual trends and patterns instead of trying to remember what happened last Tuesday. STOOLY IS FOR - Anyone curious about understanding their gut health - People tracking how diet, stress, or lifestyle changes affect digestion - Those managing IBS, IBD, or other digestive conditions - Health-conscious people who want data about their body without paying for hardware - Anyone whose doctor recommended keeping a stool diary Your gut.
