Pay It Forward.

Carma is an iPhone app that harnesses the goodwill and compassion of individuals in order to create a network of users that help one another avoid frustrating parking tickets. The concept is simple: any user that notices a parked car in danger of being ticketed or towed can use the car's license plate number to send an alert to the driver who can then act accordingly. Out of gratitude, the driver will hopefully return the favor to another driver later down the road. In the end, everyone wins . . . except parking enforcement.
