Apple has launched an official online directory of more than 200 web applications built to run in the iPhone's and iPod touch's Safari browser.

This move reiterates Apple's position that third-party developers will only get official backing from the company via Web 2.0 applications that function only under the embedded version of its Safari browser.

The information from Apple reads: "Like to get the latest news from your Facebook friends? Check the movie listings at Fandango? Browse the newest photos posted on SmugMug? Update your weblog with TypePad? Or play a great game of Big Bang Sudoku? It’s all possible. Simply by visiting www.apple.com/webapps/ on your iphone or iPod touch, browsing the library, and bookmarking the web apps you enjoy".

Apple has taken this route as it states it is the only way is can maintain the security and integrity of its mobile Mac OS X platform.

The directory organises the applications into categories such as Games, News, Productivity and Utilities and there is also a guide for developers about creating applications for the devices.
