The updated app gives the iOS device control over iTunes libraries and allows you to send music to AirPlay supported speakers and audio devices around your home as long as they're on the same Wi-Fi network as your iPad, iPhone, or iPod Touch. Additionally, the new version allows you to control the new Apple TV and even enter text with the on-screen keyboard so you don't have to scroll through playlists to find what you want to play.
The Remote app looked all but abandoned, but with the amount of movement and change in Apple's iOS devices and the release of the new Apple TV, it makes sense now would be the time to update it with new features. The new Remote app includes support for AirPlay, so your other Macs and AirPlay-supported devices (if you have any) can be managed directly from your iOS device.
Perhaps one of the biggest changes in the new Remote app is the updated iPad interface. The iPad version of the app includes a wide-screen iTunes-like display that allows you to scroll through your songs by cover art and search your music library by keyword instead of scrolling through all of your music to locate a specific song you want to play.
Additionally, the iPad version of the app blows up the album art of the currently-playing song and puts playback and volume controls around it, making it look and feel a lot more like the iPod and iPhone version of the app.
Both new versions give you gesture control over the new Apple TV, and allows you to ditch the included remote and use your fingers instead. You can play, pause, drag and drop, and move on-screen selections right on your iOS device. The app is completely free, requires your device have iOS 3.1.2 or later, and is available now in the iTunes App Store.
