Navistar wanted an iPhone app offering real-time parts inventory, dealership locations, and promotions information with the ability to make rapid changes to the information that users see. Ratchet wrote a custom service layer integrating four feeds – two maintained externally and two we created – to keep their application up-to-date and in users’ hands … rather than in Apple's app review queue. The app allows users to search for dealers by proximity to their current location, zip code, name, parts availability and service offerings; serving up detailed parts and specials available at each dealership.
