If this appears to do nothing
Scanning does work but it took me awhile to figure out how. When the app shows the ISBN and vibrates the book is stored and you then have to Bluetooth connect to the Mac version to get the books from the iOS app and into your library. So the app works like other barcode scanners - obvious once you know how and easy once you have the BT connection working. A simple help screen in the app (or even a guide on the website) would save this from bad reviews. To get the Mac library onto the phone you have to turn Bonjour sharing on in the Mac app preference and load from the Share button on the phone.
