Since Iceland has a very small population of 320,000 people, a lot of its citizens are related to each other distantly. To prevent Icelanders from committing the an unacceptable social practice of falling in love or marrying their close relatives, they are tapping technology's help.

Friorik Skulason, an anti-virus software developer, created an online database titled The Book of Icelanders to help residents trace their genetic lineage. Then three app developers used the database to make an anti-incest feature.

The app, currently available in beta for Android phones, has an interesting line - Bump in the app before you bump in the bed.

Users of the app literally have to bump their mobile units together to verify how they are related. It activates another feature that will notify the two people who bumped their phone how closely related they are to one another.

However, the developers - Amar Freyr Aoalsteinsson, Hakon Prastar Bjornsson and Alexeander Annas Helgason who collectively call their group Sad Engineer Studios - said they have no proof yet that the app did actually prevented two close kinsmen from developing a romantic relationship.

They said they app could be replicated in other countries, but these nations should first have a complete database of all residents.

"We aren't sure if other countries have such interesting interwoven bloodlines like we do, but we're pretty sure the Icelandic genealogy database in unique in its completeness. So even if the need is there, other countries would first have to build a similar database before considering a smartphone implementation," the developers were quoted by Digital Trends.
