The iPhone app Yo has to be one of the most pointless phone apps I’ve ever come across. It is so basic that it only does one thing – send a “Yo” message to your friends, yet since its release it has already been downloaded over 50,000 times and users have sent over four million Yo’s.

The creator of Yo, Or Arbel, explains that Yo took just 8 hours to produce and has been labelled as a “context-based communication app”. You may wonder what the point of sending a message that simply says “Yo” is but Arbel says that “you usually understand what the Yo means based on who you get it from and when you get it.”

The app was released on April 1st so you’d be forgiven for thinking that this was just an April Fool’s joke but Arbel reveals that he’s received an investment of $1 million for Yo from his former boss. Why? – because his former boss wanted a simple way of telling his assistant that he needed her!

So now we know this isn’t someone just pulling our leg,  what will the $1 million go towards in developing Yo? Well not very much according to Arbel, who says that the app will not be featuring any other messaging functionality in the future, so we’ll just have to see how this one develops.

Yo has received some interesting comments, with one review that reads: “Not just a means of simple but effective communication, Yo is a way of life.” “Since downloading Yo, all my relationships have improved and I’ve regrown most of my hair.”

Have you tried Yo? If you have, we want to know whether you think such a simple app is worth downloading and how you feel about receiving a “Yo”.
