Slappstick (http://www.slappstick.de) has updated AppyDays, a Mac OS X utility for tracking discounted apps, to version 1.4. Users can now filter Mac App Store categories. Also, there are now separate filters for every platform.
With AppDays one click directs you to the Apple App Store or Mac App Store immediately. The small application window can be left open while people work on their computers.
AppDays displays discounted apps in the stores. It sports filters available for price (Mac and iOS) and category (iOS only).
AppyDays for Mac requires Mac OS X 10.6 or later. It’s available for free at the Mac App Store in the Reference category.
