YouTube has launched an update for its iOS app, which is designed for the iPad, and has some updates for the iPhone 5 and iPod Touch.

“Just in time for the holidays, now you can download or update the YouTube app with a look designed for the iPad and iPhone 5, enhanced AirPlay support, videos that start faster and play more smoothly, and improved accessibility with VoiceOver,” Google software engineer Horia Ciurdar says. “Enjoy Tastemade on iPad in full screen glory, or hours of flipping through Ryan Higa videos on your iPhone 5 or iPod touch.”

Google launched its YouTube app for iPhone and iPod Touch in September. YouTube is now available on 400 million devices. People are watching over 25% of YouTube on mobile devices – over a billion views a day, Google says.

The iOS update is rolling out globally today.
