We have just released new app for searching, playing, downloading and uploading videos on Facebook: VideoBuzz for Facebook.
This free app provides one-click access to all videos your friends and you have ever shared on Facebook, including Vimeo, Coub and YouTube videos. Just tap on your friend's name and VideoBuzz will do the rest. Play videos in the app, leave comments, share videos you liked with other apps or download them to your device. Moreover, nothing stops you from uploading your own videos using built-in facebook video uploader.
