Slimba — your smart calorie plan for steady, healthy weight loss. Set a realistic goal, get a personalized daily calorie plan, and track every meal in seconds. Whether you type what you ate or just snap a photo of your plate, Slimba's AI assistant does the math for you — no manual searching through endless food databases. HOW IT WORKS • Set your goal. Tell Slimba your current weight, target weight, and target date. We'll calculate a safe daily calorie balance to get you there. • Track meals the easy way. Type a quick note like "1 banana and a coffee with milk" — or send a photo of your plate. The AI assistant identifies the food, estimates calories, and logs it for you instantly. • Stay in the green zone. A simple speedometer shows where your daily balance stands: green means you're on plan, yellow is a warning, red means you've gone over. No spreadsheets, no guesswork. • Bank your savings. Days when you eat below plan add calories to your "fund" — you can spend them later on a celebration dinner without breaking your goal. • See your progress. Daily, weekly, and monthly statistics show calories consumed, calories burned, and weight trends over time. Watch your goal calendar fill up with green days. WHY SLIMBA IS DIFFERENT • AI-first logging — no more scrolling through "Apple, medium, raw" vs. "Apple, large, raw." Just describe or photograph. • Built around a real plan — not just a tracker, Slimba calculates the exact daily balance you need to reach your goal weight. • Forgiving, not punishing — bad day? The fund system lets you recover without guilt. • Clean, distraction-free design — focus on your goal, not on the app. • Privacy-first — your data is encrypted, never sold, and AI photo analysis is opt-in with full disclosure. FEATURES • Personalized daily calorie target based on your goal • AI text and photo recognition for meals • Activity logging (workouts, walks, sports) • Daily, weekly, and monthly statistics • Goal calendar with progress visualization • Calorie "fund" for flexible eating • Weight tracking with trend charts • Reminders and gentle nudges • Support for both metric and imperial units SUBSCRIPTION Slimba offers a free 7-day trial. After the trial, full access requires a subscription. Cancel anytime in App Store settings — no questions asked. PRIVACY We take your data seriously. Slimba uses OpenAI's GPT-4o-mini for AI features; we clearly explain what is sent, ask for your explicit consent, and never share your data for advertising or model training.
