We know Google doesn’t develop apps for the Windows Phone platform, but Windows Phone developer community fills in quite well. While we don’t have an official YouTube app for Windows Phone, we’ve got terrific third-party YouTube apps like MetroTube and myTube since quite a while.
But my latest crush is Tubecast because it offers the ability to cast the YouTube video onto your TV screen using a Chromecast. Chromecast is a digital media player by Google that allows you to play audio/video content on a high-definition display by directly streaming it via Wi-Fi from the Internet or a local network. There isn’t a native Chromecast app for Windows Phone users but Tubecast offers Chromecast support, along with Apple AirPlay.
