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 food trackers hand you a number whether or not they actually have one. Asira Core tells you when it doesn't know. It's a calorie tracker and a health tracker at the same time. It reads your Apple Health data and what you ate, puts both on one page, and tells you what to do about today. Four Daily Scores Flow, Sleep, Intensity and Stress, built from your Apple Health data. Tap any of them and you'll see the readings underneath, so you can tell why the number moved. Log a Meal in Seconds Snap a photo, scan a barcode, or just describe it. Calories and macros get checked against USDA FoodData Central and Open Food Facts, and every food gets a Nutrition Score. Nothing lands in your log until you've looked it over. Targets Built Around You Calories and macros set from your body, your goal and the pace you picked. Change any of it and the plan recalculates. Coaching from Ari Ari reads your day and gets specific: which night cost you REM, what yesterday's hard session is still charging you, whether an hour earlier tonight would win most of it back. Your Morning Vitals Resting heart rate, HRV, respiratory rate and wrist temperature, each measured against your own baseline. The arrow shows which way you moved, and the color tells you whether that's worth your attention. Weight and Water Log your weight and watch the gap to your goal close. Water is one tap. Trends Over Time Sixteen metrics charted across weeks and months, so one odd day doesn't read as a trend. Reminders You Control Pick how often, or switch them off entirely. Synced to Your Account Your log follows you, not the phone you logged it on. Before You Start You'll need an account, because your data syncs across your devices. The four daily scores come from Apple Health, so if you're new to it, or you don't wear a watch to bed, those screens will say they're still calibrating rather than invent a score. Food, water and weight work on their own. Photos and meal descriptions are sent to Asira's own server to be identified by AI. Nothing else goes with them: not your name, your account, or your Apple Health data. They're never sold and never used to train AI models. The app asks before the first one, and you can say no and still use everything else. Barcode lookups use Open Food Facts. Asira Core is not a medical device. It does not diagnose, treat, cure, or prevent any condition, and it is not a substitute for advice from a clinician. Asira+ is an auto-renewing subscription ($9.99/month or $99.99/year) and begins with a 3-day free trial. Payment is charged to your Apple Account when the trial ends; the subscription renews unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://asiracore.com/privacy
