Want to like it

I have a TON of books and decided recently organizing and keeping track of what I have would be great. I downloaded this app, but unless Im missing something I dont understand the glowing reviews. The isbn scanner barely works. Manually entering books isnt really an option I want to go with, as I have a great many and it would end up taking a lot of time up. If they update it I might try it again, but as is, I think Im going to keep looking.
