Mobile Thing 3 - Utilities

I have been using ScanLife for QR codes and liked it.  This thing suggested using RedLaser Barcode & QR Scanner.  First I took a book and scanned the barcode with ScanLife, but it came up with nothing. Next I tried it with RedLaser and that one did scan in.  Came up with places I could purchase and prices.  Next I took a url and created a code.  I do like RedLaser better and have uninstalled ScanLife.
