BellySignal is a poop tracker and bowel diary for recording your daily digestive patterns. Log stool form with the Bristol stool chart, urine color, water intake, and food and habits in one place. Start without an account. KEEP A BOWEL MOVEMENT DIARY Choose a Bristol stool type from 1 to 7, record color, and note blood or mucus you notice. Add observations such as belly pain, bloating, urgency, or straining to keep a useful record over time. TRACK WATER, FOOD AND HABITS Log water toward your daily goal and record urine color. Add coffee, alcohol, dairy, spicy food, stress or poor sleep to look back at what happened around changes in your digestion. A pattern does not prove that a food caused a symptom. REVIEW TRENDS AND EXPORT A PDF See your entries together in Trends. Export a PDF summary of the last 90 days from Settings and choose whether to share it at a medical appointment. You can also export a backup file and restore it later. START WITHOUT SIGNING IN Your diary is stored locally by default. An account is optional and does not currently sync your health diary between devices. You choose where exported files go and whether to enable health-platform integration. Some health values, including stool type, symptoms and manually entered weight, are sent to PostHog, which is on by default. The Usage analytics switch controls PostHog only. Firebase Analytics receives usage events without those health values and stays active even when the switch is off. Deleting local entries does not automatically delete analytics data that has already been sent. You can delete your diary entries in Settings. BellySignal is a self-recording tool, not a medical device. It does not diagnose IBS, food intolerance or other conditions, determine the cause of symptoms, or provide treatment. Discuss concerns with a qualified healthcare professional. Privacy Policy: https://bellysignal.com/en/legal/privacy/ Terms of Service: https://bellysignal.com/en/legal/terms/

About

Bloatless

Feel good in your clothes. Know what you're eating and what may leave you bloated. Bloatless combines photo calorie tracking with a personal food and symptom diary. Snap a meal for estimated calories, then check in an hour later. Your logs help you spot potential bloating triggers. If you're working toward weight-management goals, keep an eye on your daily calorie total without typing in every ingredient. WHAT BLOATLESS PRO UNLOCKS • Photo calorie tracking: AI estimates the calories in your meal, identifies ingredients and flags common potential trigger groups. • Daily calorie totals and an optional calorie goal you control in Settings. • Meal reminders and one-tap bloating check-ins, with optional notes or voice memos. • A personal Trigger Report: potential food triggers, confidence levels and examples from your meals. Your report builds from your own meal and symptom history. HOW IT WORKS 1. Photograph your meal. See estimated calories and potential food triggers after analysis. 2. Check in one hour later. Rate how bloated you feel with one tap, including from the lock screen. 3. Compare your patterns. Choose 7 days for a first look or 30 days to collect more meals and check-ins. The tracking window is separate from your purchase's billing period. More consistent logs give the report more evidence to work with. Bloating and body fat are different. Bloatless helps you track food intake and bloating patterns; it does not measure body fat or promise targeted belly-fat loss. Calorie estimates from photos are approximate. PAID ACCESS OR REFERRAL UNLOCK Meal tracking requires Bloatless Pro or a qualified referral unlock. The onboarding example shows what to expect before you pay. Bloatless offers weekly or yearly auto-renewing subscriptions, or a one-time lifetime purchase. Available options and localized prices are shown before purchase. Every paid option includes the same Pro features. No ads. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Your account is charged within 24 hours before renewal. Manage or cancel subscriptions in your App Store account settings. Lifetime is a one-time payment with no subscription. You can also invite friends: two friends who join with your code and photograph their first meal unlock one 7-day plan. A third qualified friend unlocks a 1-month plan. A NOTE ON YOUR HEALTH Bloatless finds patterns and likely trigger foods in your own logs. It makes predictions, not diagnoses. It is not a medical device and does not provide medical advice or treatment. If your symptoms are severe or persistent, please talk to a doctor. — Privacy Policy: https://bloatless.app/privacy — Terms of Use: https://bloatless.app/terms — Support: hi@bloatless.app
