Jack of Dice review for F: Retail Barcode Generator

Though the app claims "A unique 10 digit alphanumeric code would be generated for each product **if it doesn't have QR/Barcode**", it replaces EXISTING barcodes with it's own random string of letters. There is no way to undo this other than re-entering the old barcodes, and the app does not warn beforehand that the barcode will be changed.
