"The idea was pretty much born out of frustration," said Joseph Darling of "ParkPatrol," the app developed by his Sydney-based firm to help users avoid tickets that cost what he said was at least $82 Australian ($81) a shot -- and often more.
The app lets users "sign in" and report sightings of parking officers with a single push of a button. Cartoon faces wearing a police cap then appear plotted on a map of the area, along with a notice thanking them.
The app will also alert users if a parking officer is spotted in their area and how close. Notification options for 500 meters (1,640 ft), 200 meters and 100 meters are available.”
