An article in the 19 April 2013 Columbia Daily Tribune tells of an app used in Iceland (pop. 320,000), a place where nearly everyone is related. Turns out Iceland has a huge database with genealogical details about nearly everyone. With this app featured in the article, Icelanders can bump smart phones and find out if they are related. It even has an anti-incest feature so that daters can check to see if they are a little too closely related !!
