You can scan food products as follows:
- Open the Fddb app.
- If you're using the app on an iOS device, press the “Barcode Scanner” icon in the upper right corner.
- If you are using the app on an Android device, press the blue plus sign in the lower right corner and then select "Scan".
- Scan the desired food and select an entry of the list of results.
Alternatively, you can use the barcode scanner directly in the search function.
