Controversial new app allows you to rate people's personalities

A controversial new app, which has been referred to as the Yelp for Humans, has officially launched and it has a lot of people talking.

The app was created by two friends in Calgary, Canada and it allows users to rate other people in three categories: personal, professional, and romantic - and you can rate them without their permission.

They say it's a way to reference check the people around us, like the way we would a restaurant.

The creators call your character, your currency.

It's generated a lot of online buzz - from those applauding it, to those fearing it will fuel bullying or cyber revenge.

Either way, it's now a real app with people already downloading and rating away.
