Turn your iPad/iPhone or Android tablet or smartphone into a convenient side monitor for your Windows or Mac desktop. iDisplay is a universal app specially optimized for iPad, iPhone, iPod Touch, and Android devices screens.
It works as long as the computer you are trying to extend and the Apple/Android device is connected to the same WiFi network. The downside is that it is not as smooth than duet display (but iDisplay is wireless nonetheless)
