It might be easy to tell if the hottie you’re flirting with might be your cousin, especially if you met them at a family reunion, however in Iceland, it’s not so simple. On the tiny island nation of 320,000 where almost everyone is distantly related, last names won’t give away family relations as Icelandic surnames literally translate to “father’s (name) + son” or “father’s (name) + daughter.”
Huffington Post reports that the Islendiga-App, or “App of Icelanders,” was created by three software engineering students at the University of Iceland for a contest looking for creative uses for the Islendingabok, a national registry of genealogy for every Icelander born since the 18th century. When you are a nation descended from Vikings, genealogy is a national pastime.
Arnar Freyr Adalsteinsson, one of the three students who created the app, says that two people using the app can find out if they are closely related by bumping their phones. An alarm will sound if they have a common grandparent.
