What unique app was developed in Iceland?

The risk of Icelanders accidentally sleeping with a relative is apparently high enough to justify the creation of a smartphone app to help prevent it.

Iceland isn't a big country. Most Icelanders are descended from the Norse and Celtic settlers that first began arriving on the island some time in the 700s and 800s, with few additions to the gene pool. Roughly two-thirds of its 320,000 population live in and around the capital, Reykjavík, so the chances that you're at least not-too-distantly-related to most of the strangers you walk past in the street are high. Or, indeed, someone you might meet in a bar and go home with.

The solution to this? Developers from Sad Engineers Studios created ÍslendingaApp SES(Beta), an Android app that seeks to save any incredibly awkward revelations in the future by making things clear now. It uses as its resource Íslendingabók, an online genealogical database that contains records of more than 720,000 Icelanders going back 1,200 years using as many records (church documents, census information, and so on) as possible.
