Kiwa has a collection of interactive "Qbooks" available for the iPod Touch, iPhone and iPad. These interactive books have features such as "Swipe to Read," "Touch to Hear," "Touch to Spell" and a "My Narration" function to read and record in your own voice. Some have narration built-in. You will find the ability to "paint" story pages with custom brushes, as well. The books are moderately priced (.99 cents for the iPod Touch versions up to $7.99 for the iPad HD versions). Many titles are also multi-lingual, which might be suitable for foreign language teaching. The Kiwa website reports that "support for other platforms coming soon."
