When to Use Photo Scanning
Photo scanning is perfect when you're eating food without a barcode or nutrition label. The AI analyzes visible ingredients, cooking methods, and portion sizes to estimate nutrition.
Best Use Cases:
- ✓ Restaurant meals and dining out
- ✓ Home-cooked dishes and meal prep
- ✓ Fresh produce, fruits, and vegetables
- ✓ Meals with multiple ingredients (salads, bowls, plates)
- ✓ Street food and food trucks
💡 Pro Tip: Take photos in good lighting and capture the full plate for the most accurate estimates.
When to Use Barcode Scanning
Barcode scanning is the most accurate method for packaged foods. It retrieves the exact nutrition label data, ingredients, and allergen information directly from the product database.
Best Use Cases:
- ✓ Packaged snacks, protein bars, and drinks
- ✓ Grocery shopping and comparing products
- ✓ Checking additives and preservatives
- ✓ Finding allergens in packaged foods
- ✓ Tracking exact serving sizes from labels
💡 Pro Tip: Barcode scanning gives you the full ingredient list—helpful if you're avoiding specific additives or have food allergies.
