LiveRadar is an application which helps you to find interesting people face- to-face instead of meeting them online only. You create a profile and define your interests. LiveRadar alerts you when someone that matches to your interests is nearby.
LiveRadar is more efficient than usual social network or dating websites for three reasons. (1) LiveRadar will lead you to potential matches that are close to you. You can meet them face-to-face and quickly talk about interests you have in common. (2) LiveRadar will not present you to people that are several miles from you. So you don't waste your time with people that you will probably never meet. (3) It is easy to recognize a fake profile because you can meet the owner of a given profile just after you see it.
