Like the app. overall. I've already added over 80 books with many  many more to go. A couple of issues  though. 1. There are too many steps to check off that you have read a book - select the book  select the edit icon  select notes  select that you've read it  then select save. Given that marking a book as read is a common occurrence  it seems like marking a book as read would be easier. 2. When I try to scan Barcode/ISBNs  sometimes it tells me that the ISBN is invalid  but when I enter the ISBN manually  the book is found. Beyond those two issues  though  I like the software and am looking forward to finally getting my library cataloged. Update: Since this upgraded to version 5.2.0 - It hasn't gotten any better about scanning the ISBN. Half the time it doesn't find it until I key it in manually. Also  it seems to take longer now to find the book after the ISBN is entered.
