The island nation of Iceland apparently has a bit of a problem with people accidentally porking distant family members, thanks to its limited population of 320,000 and the fact a large percentage of that lot is based in and around capital Reykjavik. A new app lets potential partners check to see if they're related, prior to engaging in... relations.
The Android app's called IslendingaApp SES. It accesses data from an online genealogical database that charts Icelandic family histories, letting users "bomp" their mobiles together to perform an instant family history check to see how, or how well, the pair are related. This is described rather grimly as an "Incest Spoiler."
