Have to pay if you have more than 50 books
I was surprised when I was told I had reached my limit of books for the free version of BookBuddy. I had spent quite a bit of time putting my books into the app. I had also backed them up into Dropbox. At this point I couldnt see abandoning my mission as it was so much fun. Be prepared to spend $5 bucks if you have lots of books!
