I love this app!
I find the bar code scanner works pretty well with more recent titles. Older books do not always seem to be recognized correctly. In those cases, you can search on the ISBN number. Worst cases, you can manually enter the information and take a picture of the cover to go with it.
But most of the time, the scanner or the ISBN works, and wow! What a time-saver compared to my old database where I was trying to enter all of this info manually.
I logged a couple of minor bugs, and promptly received an email response from the friendly developer. He updated the product already fixing one of the issues, and another fix is on the way.
Totally worth the 99 cent upgrade to the full version.
