Thanks for your interest. Titles built for Amazon's active content system only work on Kindle devices sold by Amazon, not in Kindle for iPad (etc.). It's a restriction we can't do anything about. But, even if that restriction didn't exist, the exclusive Puzzazz user experience you'll find in all our Kindle titles is designed specifically for -- and great on -- Kindle devices. We wouldn't take this UI and UX to the iPad any more than we would bring a PC UI to the Kindle.
We will have products for the iPad and other devices in the future.
