Very good value

I do not collect video games per say but I do own a large amount of them. This app although costing $2.99 for the video games section in app seems like a rip, the actually quality and level of detail put into this app really pays off.
You can scan multiple barcodes like you are at a grocery store, modify the preexisting input of a game if something is incorrect(hardly ever is) and it displays it in a nice iBooks style shelf. It also has a good wish list section too.

Very useful and I rarely buy in app purchases.
