Yog—a new app for the iPhone—helps connect runners so you never have to jog alone again. The app lets you schedule a run and invite friends via Facebook or your contacts. You can also make the run public and allow anyone to join. It will match you up with other runners at your skill level. When the run is about to start, the app counts you down so you know when "the gun goes off." After the run you can see how your time compared to everyone else's. Oh, and the app is $FREE.99. Peter Pelberg—one of Yog's co-founders—says he came up with the idea for the app after moving to New York City and realizing he had become less active. [Mashable]
