The major free downloads from YouTube are its player apps for mobile devices using the iOS and Android operating systems used by many smartphones and tablets, including the iPad. YouTube also offers free players for the Sony PlayStation, Microsoft Xbox and Nintendo Wii game consoles, as well as many smart TVs. These applications are often pre-installed on devices and are also available through storefronts such as the Apple App store.
Apps designed for YouTube playback are often more fully featured than the players used in the Web browsers included on smartphones and tablets. For example, most mobile browsers as of 2015 do not support Chromecast streaming, which is a YouTube feature that allows video to be controlled from one device and displayed on a TV or monitor equipped with a Google Chromecast receiver. However, the free YouTube apps for both iOS and Android fully support Chromecast streaming of YouTube videos.
Another free YouTube download for iOS and Android devices is the YouTube Gaming app. Despite its name, this app is actually a version of the YouTube player app that is geared towards gaming-related video content. The YouTube Gaming app is also optimized for live streaming of gaming events, such as live demonstrations or tournaments.
