I am trying to find an app to keep record of all the books that I have/want to read. I want to be able to scan them in. I have tried several different apps and everytime I scan... I get an error. I have other apps that scan, like my fitness pal and it works great. I scan my food items in and it brings them right up. Is there a setting that I could check? Is there a reccommended app for my phone (LG Revolution)? Any Help is appreciated!
