The DoIP Remote is an application for iPhone and iPod Touch that can connect to and control DoIP devices. You can buy the application in the iTunes Store (click here).
The DoIP Remote application currently supports DoIP devices that can be discovered through Bonjour (DNS-SD/mDNS) and that support OSC-over-UDP as transport. More transports will be added in the future. TJShow Remote supports most basic parameter types (int32, double, bool) and shows user-friendly icons for methods that are part of the EP-Basic specification. Methods without any parameters or only a single one can be controlled directly from the method list of a particular device; methods with more than one parameter can be configured and executed from a separate screen.
