Excellent except for... This is generally a very good app. Scanning of books is simple and when linked to Goodreads it really comes into its own. I used it lots and would have given it 5 stars. But there is no auto backup or option to sync your catalogue easily on to the cloud. As a result  should you have your phone stolen or upgraded or be forced to do a factory reset (thank you lollipop) then you will lose the entire lot! As I have a library of over 1000 books  I won't be using this app to rescan then all again.
