Reuss New Media has released Dropkick 1.1 (http://dropkickapp.com), available for iOS and Mac OS X in the Apple App Store and the Mac App Store.
According to the folks at Reuss New Media, the task management app aims for simplicity by focusing on the essentials: add tasks, drag-and-drop to prioritize, and check things off. Version 1.1 adds the option to create multiple lists, back-to-back task creation in the iPhone version, and more efficient keyboard navigation on the Mac version.
Dropkick is available as a free trial. Upgrading to the full version is an US$1.99 in-app purchase for the iPhone version and $4.99 for the Mac version. The application is compatible with iOS 3.0 or later and Macs running OS X 10.5 or 10.6. The Mac version is also available from the Mac App Store where 10.6.6 is required, although a free trial is not available there.
