Book Writer Version 2.0 is now here w/ a brand new user interface that makes it easier then ever to create stunning digital books/presentations. BW is one of my favorite iOS apps that can be used in a number of different ways for education such as: digital storytelling, "flipping" a classroom, and more. It's very user friendly, has a drag-n-drop interface and allows for users to not only add images/videos, but record audio as well.
I highly recommend checking out Book Writer by clicking here!!!
