There’s a new app for your phone and the only thing it can say is ‘Yo’. Sounds silly but it has raised a million dollars from investors and has attracted 50,000 users. Yep, the only thing it says is ‘Yo’.

It was created by Or Arbel in just eight hours and has taken off on Twitter as a running joke. It is very simple to use, type in someone’s name and it will send a push notification that says ‘Yo’.  It cracked the top 150 apps in Apple’s App Store and is now ranked at #47.
