The loss of the YouTube app in iOS 6.0 may not have caused as much of a stir as other changes, such as a lackluster Maps program and a redesigned App Store that leaves much to be desired, but for heavy YouTube users, the change was noticed. YouTube videos can still be accessed through the web page, but the user interface was not nearly as easy to use as an app.
After first releasing a YouTube app to coincide with the iPhone 5's release, Google has now updated the app with universal support, which means it will recognize and support the iPad's and iPad Mini's larger display. The new app allows you to sign in to gain access to your favorite videos and has a much better interface for browsing YouTube titles. It also has better support for video out, which allows you to stream videos with AirPlay.
Google claims the YouTube app will also load videos faster, though I couldn't tell much difference between the app and the website. Perhaps when the site gets more congested with traffic, the difference will be noticed.
Google also released an updated Gmail app for the iPad. The Gmail update adds support for multiple accounts and a cleaner inteface.
