Book Writer is a fantastic iOS app for digital storytelling that lets users create interactive digital books, PDFs, and more. Educators are using this to Flip their classroom, create tutorials, photo books, presentations, and Project Based Learning. It's a simple app to use that has a drag-n-drop interface and lets users upload images, videos, audio, text, etc.
