The app is quite good overall — the interface is clean and the features are useful. However, it struggles to recognize barcodes from food products sold in Taiwan, which significantly affects the convenience of use. I hope the database can be expanded in the future to include barcodes from popular local brands and products in Taiwan. This would make the app much more user-friendly for people here and could also boost user ratings and adoption. It would also be great if users could contribute missing barcode data themselves.
