Quite recently I started using this URL Shortener app to shorten the URL of many videos. URL Shortener is required to send shorter links to open various videos and their features.
Major problem with this app is that it refuses many YouTube videos. If you are running a channel you need to share links in shorter form. It should convert videos into bit.ly format easily.
Although what so ever URL it accept are shortened in less than a second. So proficiency is quite high. But use is limited.
