The YouTube app for iOS offers a quick and easy way to search, save and upload videos on the world's most popular video sharing site.
Key features include the ability to search for videos and, if you wish, to then continue searching while the current video plays in a small in-picture player in the bottom right of the screen.
You can also subscribe to other accounts and receive notifications about when new videos have been uploaded, and keep track of your own videos and the views and comments they have had.
Another notable feature is the support for Google Cardboard natively within the app, which was added to the iOS version in update 11.18.
The app is 125MB in size and requires iOS 9.0 or above to work.
