Few things enrage normally calm people like finding a parking ticket tucked under the windshield wiper of their car. Parking tickets can be infuriating, especially when they seem undeserved. (Officer, there’s no sign saying I can’t park here!). But most people don’t want to invest the time and energy to would take to dispute them. Now there’s a new iPhone app, Fixed, that will fight parking tickets for you. The app, expected to launch next week, will do the heavy lifting of contesting a ticket: suggesting reasons it might be invalid, gathering supporting evidence and submitting the proper appeals paperwork. If the driver beats the ticket, they pay Fixed 25% of what the citation would have cost. If they can’t get out of the ticket, Fixed doesn’t charge them anything. In this way, Fixed hopes to add navigating bureaucracy to the list of urban tasks and nuisances — catching a cab, ordering food, finding a place to crash — made easier by popular tech startups.
