An update to one of our favorite OS X apps, Fantastical, is the latest to add support for Apple’s new Retina display Macs. High resolution support isn’t all, there are a few other important improvements to the calendaring app as well: repeating reminders are now simpler to enter, and tapping the space bar can now toggle the completed state for reminders. Developer Flexibits is getting the update (version 1.3.2) out just ahead of today’s Mountain Lion release, which is good since it's the first version to add support for the new OS.

If you haven’t used Fantastical before, the small app sits in your menu bar, and a click or shortcut key press lets you add events and reminders quickly using natural language processing. The update is free for owners, otherwise a 50 percent off promotion both on the Mac App Store and Flexibits’s own site brings the price down to $9.99. If you’re still on the fence, you can always check out our interview with the app’s creator, Michael Simmons, or download the free demo to check it out for yourself.
