Overall I love the app. My only 2 problems is 1) after I download a book to my device and listen to it at work where I do not have wifi and uses my data. 2) I hate I can only borrow 5 books a month. I can listen to 5 books in a week. I wish they would up the number of books you can get or once you finish a book as long as you return it why cant you get any more? The selection is pretty good but I wish they would get more newer books like other listening sites do. But this is a free app and I do get free books so I am extremely happy about that. I do not have time to read but I listen for at least 9 hours a day.
