Independent software developer Christian Kienle has introduced Store News 1.0 (http://store-news-app.com/), his free application for Mac OS X, now available in the Mac App Store.

Store News offers a way of finding out the best deals in the Mac App Store. It shows categories of apps that are totally free and apps that still cost a little bit of money.

Users may share what they’ve found via Twitter. Store News requires Mac OS X 10.6 or later and can be found in the Productivity category.
