148Apps (http;//www.148apps.biz/), which offers iPhone development news and information, says the Apple App Store has over 250,000 apps from 50,304 publishers as of Friday, just slightly over two years after it opened.

AppShopper.com, which keeps a similar list, has the total at 253,777 apps, including 24,334 for the iPad, notes “Fortune” (http://macosg.me/2/ss).

A 148Apps pie chart that breaks down the list by category shows that books (with 17%) have now overtaken games (14%) and entertainment (11%). According to an analysis posted by Royal Pingdom Friday, roughly 70% of the offerings on Apple’s store are paid apps. On Google’s Android Market, by contrast, 64% are free, notes “Fortune.”
