Grundigee is a virtual remote control that lets you control your Grundig TV. To use the Grundigee remote control, you must have your iPhone/iPad on the same wifi network as your TV (the application communicates with your tv through the wireless). With a realistic design you can use all the functionality of the real Grundig remote. "Launch the app, control your tv that's all you have to do..." Grundigee works with all the Grundig smart TV.
