Sonar's mission statement is simple. It is a mobile application that helps you learn about and connect with likeminded people nearby. By geotracking your current location via Foursquare check-ins and aggregating public information gleaned from your social networks the app will let you connect with other users who like the same things you do.

If you're in a party and you want to talk to the mysterious stranger lounging near the bar and you want to talk to him, what do you do? You could go up to him and introduce yourself or you could whip out your phone and use Sonar. You can then use the app to introduce yourself on Twitter or find out if you have the same likes as he does. Sonar's helping lonely people around connect with similar interests.

The app works best if you really invest yourself in it. You need to be receptive and show other users who you are. It's not as pathetic as it sounds. It's cool in a techy way.

Founder Bret Martin describes Sonar best. He said that, "its simple-you open up Sonar and we tell you that the guy sitting across from you is Facebook friends with your college roommate, the dude by the jukebox is a VC that you follow on Twitter, and the cute girl by the bar also likes Arcade Fire and Hemingway."

It's a simple and elegant concept. And a practical application to the hyperlocal technology. You need to be honest for the concept to work. And you're intended should also be wired in as you are. To thrive this app needs to attract users who would be willing to connect their personal lives in the social media.

Does it sound like it would be a stalkers favorite app or the lovelorn best chance at happiness? We'll just have to see.
