Your food photos never leave your phone.
PocketMacro turns a photo of your meal into an editable calorie and macro entry — and does it entirely on your iPhone. The AI model runs on-device, so your photos are analyzed in memory and immediately discarded. Nothing is uploaded. No account, no subscription required to keep your data, no analytics, no ads, no tracking.
HOW IT WORKS
• Snap a photo of your meal (or pick one from your library)
• PocketMacro identifies the foods, estimates portions in grams, and calculates calories, protein, carbs, and fat
• Review the estimate: every food, weight, and value is editable before you save
• Uncertain about something? Each estimate shows an honest uncertainty range instead of pretending to be exact
YOU STAY IN CONTROL
• Correct any item by typing what actually changed ("that was brown rice, about a cup")
• One-tap serving chips (½, 1, 2 servings) for quick portion fixes
• PocketMacro remembers your usual portions and suggests them next time
MORE WAYS TO LOG
• Barcode scanning with nutrition lookup
• Food search (online via USDA FoodData Central, or fully offline with the local database)
• Custom foods and saved meals for things you eat often
PRIVATE BY DESIGN
• All meal logs, profile data, and history are stored only on your device
• Optional Apple Health integration reads weight, steps, and workouts — on-device, read-only
• Export your data anytime to a portable JSON file; delete everything with one tap
• Works fully offline after the one-time model download
WORKS FOR YOUR GOALS
• Personalized calorie and macro targets from your profile and goal
• Daily dashboard with remaining calories and macro breakdown
• Meal coaching suggestions that inform without judgment
A note on the download: the first launch downloads the AI model (~2.6 GB) over Wi-Fi. That's the price of keeping analysis on your phone — after that, no photo, meal, or personal detail is ever transmitted.
