ESPN ScoreCenter, which is sponsored at launch by Lexus in the US, gives fans one-touch access to scores from nearly 500 leagues in nine sports (football, soccer, basketball, ice hockey, baseball, golf, tennis, auto racing) with two others available in the next week (cricket and rugby).
ScoreCenter will also be available in five local languages including Spanish and Portuguese as well as English.
Powered by ESPN's extensive global scores database, ESPN ScoreCenter will allow fans to set personalised favourites, and in many cases will deliver the fastest and most reliable scores and game details available on mobile platforms.
The app is ESPN's third to the App Store and it follows ESPN Cameraman, a photo matching game, and the ESPN Arcade Spelling Bee game launched May.
ESPN Cameraman has already been downloaded millions of times and is a Top 20 sports app in both free and paid categories.
The ESPN ScoreCenter app is available for free from Apple's App Store on iPhone and iPod touch or at itunes.com appstore.
