The number of apps currently available for the iPhone, iPad, and iPod touch through Apple's App Store has topped the 1 million mark in the United States. That detail doesn't come from Apple, but instead from the app discovery site AppsFire.
Apple's U.S. App Store tops 1 million titles
Apple hit the 1 million mark worldwide about two months ago, although at the time the U.S. App Store was still showing fewer apps. Of those million apps, 473,000 were iPad optimized.
Just because there are over a million apps available in the U.S. App Store, however, doesn't mean they're all quality titles. While there are many great apps available, others are poor knock offs of quality apps, horribly tasteless games, or simply really bad ideas turned into really bad apps.
