I use this app all the time. Not only is it great for QR codes to check out new apps for my Sprint HTC Hero, but the barcode scanner works great for, duh, barcodes too. This is a wonderful app to show off your phone. Scan a barcode and look up the item. People think it isn't possible. They are amazed at how quickly the app works. This is one of my everyday used apps. Try it and you will not be able to live without it.
