iPhone, iPad, and iPod touch users could always stream Netflix and YouTube to Chromecast devices, but now they can set up new Chromecasts as well with the new Chromecast for iOS.
The app scans for existing Chromecasts and helps you set up new ones, which is handy if you don't have an Android device around. Chromecast may not be super useful yet since we're still waiting on third party app support
