Simon & Schuster have released a series of Choose Your Own Adventure apps for $3.99:

Instead of turning to a particular page to make a choice, the U-Ventures apps allow the reader to tap the screen and enjoy, with sound, light and other special effects — music and alien voices, for example — added to the titles, as well as new variations and endings dreamed up by Packard. Enhancements include readers having to remember codewords and type them in to affect the course of the story. Packard is particularly excited about “very fast-paced segments”, which would have taken up too much space in a printed book. “There’s no such problem in cyberland, and we take advantage of that,” he said. “Because we don’t have printing costs, we can have many more pages and colour illustrations.”

I remember going through a whole series of Choose Your Own Adventure books as a child – I must say that I’m already looking forward to the rest of the apps.
