This app allows you to listen audiobooks offline. When you play back audiobooks in this app, you can adjust the speed (tap the Speed button at the bottom left), skip ahead or back 30 seconds, and set a sleep timer. You can also access book chapters. Tap the chapters button at the bottom right of the window, and you’ll see a list of chapters. The app can play books you’ve synced via iTunes File Sharing. You can also add books from Dropbox or other cloud services.
