This app provides you with a way to view the most updated problem solving card text, all the Konami published rulings and previously published rulings on older cards. Once you download a compatible database, the information is stored on your phone and viewable while offline so you don't need an active internet connection.
The app has been updated to support new Pendulum monsters, displays the Forbidden and Limited information about a card, and automatically updates when you start the app so you always have the latest card information. These updates happen in the background so you can use the app while it is being updated. Finally, the app now supports card images when available!
