Most AI calorie trackers guess. NutriSync asks. Other trackers scan your plate, guess a number, and move on. No questions, no verification, no accuracy. NutriSync runs a real pipeline: a triage model picks the right approach, the analysis breaks your plate into ingredients, and when something's genuinely ambiguous it asks one short question instead of inventing an answer. Grilled or fried. Whole milk or skim. That's the difference between a number and your number. ADAPTIVE AI SCANNING Every meal goes through a multi-step pipeline: the AI identifies what's on your plate, then asks specific questions — portion, ingredients, preparation — instead of guessing. Results are checked first against a verified nutrition database that gets sharper with every scan. - Ingredient-level breakdown, not one lump calorie number - Follow-up questions only when the answer would actually move your macros - Barcodes and packaged foods attributed as ingredients on your plate - Fix any entry in plain language: "double the rice" - Batch-scan a whole day (Premium) Shoot every angle — and every package on the table. Not point-and-pray. Verified accuracy. ADAPTIVE TARGETS Most trackers give you one static daily number you find out you missed at 11pm. NutriSync splits your day into macro windows — pre-lift, post-lift, dinner — each with its own protein, carb, and fat target. Big lunch? Your dinner target adjusts. Skip a snack and those calories roll forward. You always know how much you have left and when to eat it. ADAPTIVE TDEE Other trackers ask how often you exercise and estimate your burn from a dropdown. NutriSync calculates your actual TDEE from your weight trend and real intake over time. A cut or bulk that stalls gets corrected without touching a setting. Real numbers from real data. WORKS WITH APPLE HEALTH NutriSync connects to Apple Health. With permission it reads steps, active and resting energy, weight, heart rate, water, and workouts — and on unusually active days, credits part of that extra burn back to your budget, up to 500 calories. It can also write your scanned meals and workouts back to Health. Optional; change it any time in Settings. TRAIN (turn on Track Workouts in Progress) - Log lifts exercise-first. No forms, no timers, no start/stop - Up Next tells you what to train and what to load, from your own history - Never done an exercise? Your starting weight scales from the lifts you HAVE logged, plus bodyweight, sex, and training age - Automatic PRs, strength trends, and weekly volume - Track Workouts logs lifts only — your adaptive TDEE (and Apple Health, if connected) already covers training burn BUILT FOR ACCURATE MACROS - Protein, carb, and fat targets for cutting, bulking, or maintaining, with phase planning toward a goal weight - Daily check-ins that move the numbers - Micronutrients, not just the big three - Weight trend that ignores daily water noise - Works offline — scans queue and sync when you're back COACHING Link a coach and they set your windows, macros, meals, and training programs from their own dashboard. Their plan lands in your app; your logs land in theirs. HOW IT WORKS 1. Shoot every angle — and every package on the table 2. Answer a clarifying question if something's genuinely ambiguous 3. Get calories and macros, ingredient by ingredient 4. Your remaining targets update automatically NutriSync is built for anyone serious about their macros — cutting, bulking, or maintaining. No wellness BS. No motivational quotes. Just accurate numbers and a system that adapts. NutriSync Premium is an auto-renewing subscription with monthly and yearly options (a free trial may apply). Payment is charged to your Apple ID. It renews automatically unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel any time in Account Settings.

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.
