What Makes a Good Food Barcode Scanner?

Database coverage: Does it recognise barcodes from your country and the brands you buy? Larger databases mean fewer "barcode not found" errors.

Serving size accuracy: Does it log the correct serving size, or do you need to adjust every time?

Speed: How quickly does the camera lock onto the barcode and return results?

Free vs. paywalled: Some apps lock barcode scanning behind premium subscriptions.

Integration: Does the scan log directly to your food diary, or require extra steps?
