Apple Vision Food Scanning

Use your camera to automatically extract nutritional data from food labels and meals.

Apple Vision Food Scanning

VitalSync uses Apple Vision to scan your plate or food label in real time, then searches the USDA FoodData Central database to retrieve verified nutritional data. Logged values are automatically checked against your preferred diet profile (DASH, Mediterranean, Low-Carb, and more).

How It Works

Tap the Camera icon in the Nutrition Log.

Choose Photo, Library, or Barcode mode.

Point your camera at a meal, food label, or packaged food.

Apple Vision identifies the ingredients or label text; VitalSync then queries the USDA FoodData Central database for verified macros.

Extracted values include: macros (calories, protein, carbohydrates, fat) and minerals (sodium, potassium, sugar).

Review the values — Vision-estimated fields are highlighted in blue.

Adjust any values if needed and tap Save.

Tips for Best Results

Ensure the food label is well-lit and in focus.
For restaurant meals, photograph the entire plate from directly above.
For packaged foods, the barcode scan mode is generally more accurate than photo scanning.

Confidence Levels

After a barcode scan, VitalSync shows a product verification card with the product name and scan confidence level. If confidence is low, review the values carefully.

Photo Lightbox

Meal photos are saved with each log entry. Tap any thumbnail in your history to open the full-screen lightbox with pinch-to-zoom and share options.
