Joypad Game Console is your dashboard for all Joypad Enabled games. Joypad Enabled games can be played on your iPad using your iPhone as the game controller.
Install this app on your iPad, then install "Joypad Game Controller" on your iPhone. The two applications will find each other over WiFi and sync up. A controller will appear on your phone, which you can use to navigate the dashboard. When you launch a game, a controller specifically built for that game will appear.
Plug your iPad into a TV for an even better experience.
