VidMate

Vidmate is an app that lets you download videos and songs from Vimeo, YouTube, Dailymotion, SoundCloud, Metacafe, and loads of other multimedia sites. You can download videos from practically any video-hosting site.

With most of the sites, you can choose to download the file in different qualities, including HD. All the videos will be saved to your virtual library and ordered by date of download.

In Vidmate settings you can choose the different sites you want to show up on the main interface. By default, you only have shortcuts to the most popular ones (YouTube, Metacafe, Dailymotion, etc.), but you can manually add more than 20 different sites from which you can download millions of videos and songs.

Vidmate is an excellent app for downloading videos from any site.
