PathCrosser

PathCrosser is a conversation starter, a matchmaker, a resourceful guide, but most importantly, its a fun way to see where you and your friends have crossed paths. You can even find out new places to try by looking at the spots your friends have been!

Simply connect your FourSquare and/or Facebook Account to import all the spots where you've checked in and you'll be PathCrossing in no time. If you don't have a FourSquare or Facebook Account, no problem. You can click all of the spots you've been and all the spots you want to try.

* FROM ReadWriteWeb: The fun part about using this app is that it can be a great conversation starter - bump phones with a friend and, all of sudden, not only do you see each other's travels by way of your checkin history, the app's matchmaking engine tells you whether or not you and your friend have similar tastes and interests.
