iPhone
Your meals never leave your iPhone. Snap any plate for calories & macros in seconds, then ask your private AI nutrition coach what to eat next. No account needed.
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.
