A full version app for iPhone, by Evan Schoenberg M.D..
This app allows you to use your Apple device as a remote control for your Mac. It works over the wireless network, so you don’t have to be close to your Mac to control it.
The app can switch applications, pause and play audio and video, and use the iTunes Visualizer. The app is compatible with most of the major audio and video applications. You can control programs like iTunes, Front Row, QuickTime, DVD Player, Keynote, and more.
It’s a great app for people who don’t have a remote control for their Mac and want to control their computer programs from their mobile devices.
