Signal 1.5

Signal is an app that allows you to control iTunes from a mobile device. It supports iPhones, iPods, and iPads, but you can use it with any device that has a modern web browser.

You can use other computers to control the one in which Signal is installed. The application is basically a preference pane that runs a small web server on your Mac to which other devices can connect. When you connect from your iOS device, you will see a window that resembles the iOS Music application. From there, you can pause and resume playback, go one song forwards or backwards, or access the song list and even search for a specific song. You can also play videos from the remote, but you won't see them on your phone's screen. If you connect through a computer, you will see an image of the iPhone and you will be able to interact with its screen.

In conclusion, this is a great app if you have a central computer with all your music and want to control iTunes from other devices on your network. The app becomes great when you use the Airport Express to stream music to other parts of the house. Controlling that setup with your iPhone is simply ideal.
