The Chromecast app is a free download available on the iOS App Store. With it, users can set up Chromecast to work with their Wi-Fi network, and manage settings with the device, such as device name or Wi-Fi password.
Google's app can also be used to identify and set up multiple Chromecast devices. The $35 accessory was launched in July as a competitor to the Apple TV in the home theater streaming market.
The official Chromecast app is a 6.2-megabyte download compatible with iPhone 3GS or later and all iPad models. It requires iOS 5.1 or later.
The Chromecast hardware allows users to stream content from their mobile device to their TV, much like Apple's AirPlay Mirroring available with Apple TV. Official Google apps such as YouTube for iOS already include Chromecast support.
