PREIT iPhone App
The PREIT iPhone app was a small, marketing and informational application for each of the company's 30-40 shopping malls.
The application used your phone's current location to find their nearest mall, give information about the mall, store directories, SVG based maps, calendars of events, etc.
One other engineer and I created an API for our Rails-based CMS and then built most of the native Objective-C iOS app prior to me leaving the company... at which point a 3rd party contractor finished and "polished" the application
