Startup Idea : Easiest way to meet someone

You see a women sitting alone in a pub. Who is she? You asking. Does she waits for someone? Does she planning a trip around? Looking for accomodation or job? Is she single even? But mainly, does she wants to be approached? If she is online and filled all her info into the app, and you have the same app installed, you can find her - you can search the nearest persons online to you. After that, the introduction is much more easier.
