220 Software has a great NASCAR Ultimate program for the iPhone and iPod touch. The app features the latest schedules, standings, and race results from all three NASCAR series: Sprint Cup, Nationwide and Camping World Trucks. A context-sensitive search function works with YouTube, and allows people to view race previews, reviews from other fans, and pre- and post-race commentary from professional broadcasters or the drivers themselves.
Other aspects of the app include a news section that collects feeds from ESPN, Fox, Yahoo and NASCAR.com, plus a separate section that details individual statistics on each driver in a series. A podcast and custom video directory contains material such as crash compilations and commentary.
NASCAR Ultimate is a $4 download from the App Store.
