## What is Calorie Tracker?

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
