Maybe there are better apps out there for a class from collections? This one is missing all of the things that everyone else has noted- print, export, etc. There also doesnt seem to be a way to combine libraries or move/copy a book from one library to another. Scanning ISBN numbers didnt work very well. Often it either couldnt find that ISBN or when it did, that particular version didnt have any levels listed. Searching the title work a bit better since the same title has multiple ISBNs and I was able to click around and sometimes found a one with a level. But, many titles have no levels under any ISBN. I had to spend a lot of time on Scholastics and ARs site to find levels, and come back to this app to save the book to a library, based on levels. All of the extra research made cataloging hundreds of books a very, very long process. I also posted a question on their FB page, but it looks like it takes over a week to get an answer, so Im still waiting.
