iPhoneApplicationList.com — a portal for iPhone app discovery, app reviews and videos — has launched a service named AppExchange, an open marketplace where developers can find the potential buyers for their apps and underlying technology.

There are a lot of apps in App Store developed by talented developers who don’t much time for app support and promotion, according to Andry Ignatov, owner of iPhone Application List. With AppExchange developers may find a new owner for their apps. iPhone Application List also welcomes developers of technology savvy apps to submit their apps for sale along with app engines, he says.

“Many apps in App Store are close to greatness and require just a little touch up such as PR or design improvements to become bestsellers,” Ignatov says. “App Exchange is a place to find a great app for sale and give it a second life as a bestseller.”
