I know this app has text contents as main contents. But, this app is not book. This app is a diagnostic application of quiz format!
For example, this app display randomly questions and choices. And, diagnostic results depend on what user chose. Furthermore, it is possible to log the result as history. Users can read and delete this history anytime. And, Users can enjoy by Tweet these results. In addition, we are making a realistic sensation of diagnosis by BGM.
So, this app is an app that can not be realized with a book. Please review again.
