YouTube said that the new site incorporated some of the features that were popular with users on the desktop version, such as search-query suggestions, the option to create playlists and designate "like" or "unlike" to videos.
Users can access the site through their iPhones or through Android's web browser, which means the tool is closely aligned with the online version's updates.
The decision to update the mobile offering was taken because YouTube consumption on mobile devices has grown significantly. The video-sharing website claims to currently receive 100 million video playbacks a day on its mobile site, while its video playbacks are up by 160% in 2009.
YouTube said that the online site in its previous form had limitations for mobile browsers and hardware, which prevented the mobile experience keeping up with YouTube on the desktop.
Mobile phones first enabled YouTube video uploads in 2006, and the first YouTube site launched on mobile devices in 2007, with about 1,000 available videos.
