Most calorie apps overload you with stats that you don't care about or tell you if you hit your daily goal, but don’t show how that fits into the bigger picture. HelloCalory tracks your running calorie deficit. Every day you eat less than you burn, your deficit grows. Every day you don't, it shrinks. No guesswork. Just the math that actually predicts weight loss. SEE YOUR REAL PROGRESS HelloCalory tracks your calorie deficit progress at three levels: daily, monthly, and overall. LOG IN SECONDS Take a photo or describe your meal. AI estimates the calories. Want more accuracy from the AI? Add optional details like portion size, cooking method, or whether it's from a restaurant. Prefer to enter it yourself? Manual logging is always there. Exercise works the same way. Describe your workout and intensity. AI calculates calories burned using your body stats, so the estimate is tailored to you, not a generic average. SIMPLE BY DESIGN HelloCalory tracks three things: calories, weight, and protein. That's it. No macro overload. Protein tracking is optional to allow you to decide how much detail you see. PERSONALIZED TO YOUR BODY Your daily calorie budget is calculated from your BMR. Want to adjust your BMR? Build a custom formula instead. APPLE HEALTH INTEGRATION HelloCalory syncs with Apple Health to pull your calorie burned, weight entries, and biometrics automatically. Less manual entry, more accuracy. Free vs Premium Premium gives you an ad-free experience and instant access to AI calorie estimation, no configuration needed. Free users will have ads and need to use their own Google AI key to us HelloCalory's AI features. Google AI offers a free plan that works with HelloCalory.

SyncDiet turns your dietitian’s meal plan into a smart pantry that manages itself. HOW IT WORKS Upload your nutrition plan PDF, text message, or photo — however your dietitian sent it. SyncDiet automatically detects every food item, serving size, and measurement unit. Scan your grocery receipt Take a photo of your supermarket receipt and your pantry updates automatically with each product’s name, quantity, and price. Real-time syncing Mark a meal as eaten and your inventory is automatically updated. No calculations. No manual tracking. Smart alerts Get notified before foods run low or expire, so you can stay ahead of shortages and waste. Meal plan substitutions Missing an ingredient? SyncDiet suggests approved alternatives from your meal plan, helping you stay on track without compromising your diet. WHY SYNCDIET Most people who receive a nutrition plan from their dietitian stop following it within the first few weeks. Not because they lack motivation — but because no one gives them a practical way to integrate it into everyday life. SyncDiet bridges that gap by connecting the plan prescribed by your healthcare professional with your real pantry and daily consumption, in seconds. IMPORTANT SyncDiet is not a medical or nutrition service. The meal plans organized by SyncDiet are always created by your dietitian or nutritionist. Always consult a qualified healthcare professional regarding your nutrition and health. Plan. Sync. Eat. Your diet, on autopilot.
