While there are other applications for your smartphone that can help you find a vacant spot in the car lot, this parking app does so without the use of expensive sensors. The New PocketParker app helps you find empty parking spaces by using the passive, portable sensor variety that already exist in your mobile device, rather than relying on the more costly ones that have to be installed in the individual parking spots.

Developed by a team at State University of New York at Buffalo, PocketParker uses crowdsourcing to lock down the specific spot location. Dubbed 'pocketsourcing' by the team, this idea uses the phone's accelerometer to measure and report activity. Once they have behavioral data, they can cross-reference the information with existing mapping apps and services such as OpenStreetMap.
