For every hour you spend circling a parking lot or idling while waiting for a spot to open, you waste 1/5 to 7/10 of a gallon of gas. That may not sound like a lot, but over time and combined with other motorists, it results in a lot of wasted fuel and CO2 emissions going into the atmosphere. The app ParkMobile wants to eliminate those issues by helping you find open spots in real time on your phone. The app also lets you pay for the spot with your phone if it’s metered. So no more searching for loose change to pay for parking.
