To configure MWorks for iOS, use the system Settings app. You can find all of MWorks' settings in the section titled "MWorks".
The iOS version of MWorks supports most of the configuration options available in the Mac version. At a minimum, you should change the display width, height, and distance parameters to match your device and experimental setup. If you leave the server name blank, MWorks will use the device name specified in Settings → General → About → Name.
