New App Lets Icelanders Bump Phones Before "Bumping Uglies," Alarm Sounds if They're Cousins

Sex with a new partner-whether you're a virgin on your wedding day or  taking on another one-nighter-is something that everyone should be prepared for.

First off, come with a condom. Whether you're a boy or a girl, people forget, and you don't want to ruin the mood without a barrier method. Secondly, be honest about your sex life and expect that same honesty in return. If you just visited a brothel earlier in the day, sex might not be the safest option for either of you. Or if you're partner's wearing a wedding ring, it's probably best to just shake hands and make your exit. Lastly, if you live in Iceland, a nation of just about 300,000, make sure you're not about to do the dirty with your cousin.

Well, fear not residents of Iceland! Technology has you covered.

News from Iceland reports that a team of software engineers have put together a publicly accessible genealogy website called Íslendingabók-the Book of Icelanders-to help produce an Android app called ÍslendigaApp.

Besides a bunch of other conventional search functions, the app features a "bump" function that lets two users tap phones to see how closely they may be related. In the case that you and your potential mate are a close match, an "incest alarm" will sound before things can get hot and heavy. The pitch: "Bump the app before you bump in bed."

Reviews of the application show that it's highly ranked, with a 4.5 out of 5 rating on the Google Play store. One user who commented on the app's website only regretted that it wasn't released a little earlier: "If I would have had this app last year," he wrote, according to Slate. "I probably wouldn't have gone home with my cousin."
