Started out well

This app started out working well enough on my iPhone 4. I wasnt able to import my library when I upgraded to an iPhone 6 and Im left with inputting my entire library again, an arduous task. I find the app is in desperate need of an update both in the appearance (terrible font choice) and stability. Whenever I add a new book to my library, other books will look as though they are duplicated and the app must be shut down and restarted. Please update, I enjoy the barcode scan feature and I paid for the full version.
