Independent software developer Christian Kienle has released Store News 1.1 (http://store-news-app.com/), an update of his free application for Mac OS X that’s available in the Mac App Store. The best deals are updated every 30 minutes instead of every 24 hours.

Store News 1.1 fetches the latest deals every 15 minutes in the background automatically. Also, you can now sort by price, discount, application name and category.

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.
