Plagued with bugs and just doesnt work in places

I just wanted an app to put my books in a database. Entering with the barcode scanner works 75% of the time but on older books with no barcodes the title/author search doesnt work at all. The cover might come up different as well and the look up cover function never shows any results. This app should be free for the amount of bugs and hassle
