The Ryder Cup iPhone app was commissioned by the PGA of America, European Tour, and Turner Sports. It needed to provide Ryder Cup coverage for both US and international golf audiences. The project was done under a pretty severe development timeline but it turned out beautifully. There were over 200,000 downloads in a 4 day period.

The app featured overall scoring, team scoring, match scoring, player scoring, live video and multitasking-enabled radio, highlight video, photo galleries, push alerts, news stories, course layout and flyovers, and a "smack talk" area where fans could use Facebook to chat head to head with the opposing team.

I also created a site to demonstrate the app since its content was really only live for a few days in October of 2010:
