A new Icelandic app will allow potential romantic partners to check if their relationship could be a social embarrassment.
In a small country like Iceland, where almost everybody is distantly related, entering a relationship can be a risky business.
A group of University of Iceland students developed the app that emits a warning sound if you are about to commit a social blunder.
Users can simply bump their phones together and the app taps into a database of residents and their family trees dating back to 1,200 years.
