"Book Creator is currently my favorite iPad app for creating multimedia books on your iPad. The app costs $4.99 (less with volume purchasing), but it is well worth it. The latest updates to Book Creator allows you to export your books to ePub 3.0 format. The exported file can be opened an read in the Chrome web browser using the free Readium browser extension. This is a great option as it allows a parent who doesn’t have an iPad at home to view his or her child’s work at home"
