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. ā Privacy Policy: https://bloatless.app/privacy ā Terms of Use: https://bloatless.app/terms ā Support: hi@bloatless.app
