Calorie Tracker is the private AI calorie counter that runs entirely on your iPhone. Snap a photo, scan a barcode, speak or type what you ate, and get calories, protein, carbs and fat in seconds. Then ask your AI Coach what to eat next. Everything is analyzed on-device by Apple Intelligence: no account, no cloud AI, no uploads. Most AI calorie apps send your meal photos to a server. Calorie Tracker doesn't. Every scan, voice log and Coach chat is processed locally, so your food diary stays yours and AI works even in airplane mode. WHY CALORIE TRACKER • AI Food Scanner: point your camera at a plate, a restaurant dish or a nutrition label. On-device AI breaks down the calories and macros. • Barcode Scanner: scan packaged foods for exact nutrition facts. • Voice & Text Logging: say "two eggs and a coffee" and it's logged. • Private AI Coach: ask what to eat next and get feedback on your day. Every reply is generated on your phone. • Smart Goals: enter your weight, height and target, and get a daily calorie and macro plan. • Apple Health Sync: reads weight and body data, writes back nutrition. • Progress Charts: weight, body fat, macro trends and a daily Nutrition Score. PRIVATE BY DESIGN • 100% on-device AI powered by Apple Intelligence • Meal photos, voice and chats never leave your iPhone • No sign-up and no account • Optional iCloud sync to your own private iCloud • Barcode lookups send only the barcode number to the free Open Food Facts database BUILT FOR YOUR GOALS • Weight Loss: a sustainable calorie deficit with macros that protect lean muscle • Muscle Gain: hit your protein target every day • Maintenance: stay in your zone without obsessing over numbers • Keto, low-carb and intermittent fasting friendly FULL-PICTURE NUTRITION • Calories, protein, carbs, fat, fiber and sugar • Vitamins and minerals • Custom macro splits or smart defaults • Daily, weekly and monthly insights REQUIREMENTS Requires an iPhone with Apple Intelligence (iPhone 15 Pro or later) on iOS 27 or later, with Apple Intelligence turned on.
