Calendar apps, for the most part, fall into two categories: powerful and boring or beautiful and useless. But developer Birdsoft is trying to redefine the genre with its app The Grid.

And it has just been updated with a number of improvements while continuing to be free.

Version 1.1 of The Grid now allows users to view their calendar in landscape mode on the iPad. And along with three calendar font sizes to choose from, a 20-minute default length has been added for events.

Users can also take advantage of the new Move Event button when ironing out their calendars.

The calendar is defined by its very simple UI and navigation. Some of the highlights include the ability to save a new event as a template for later use and the ability to drag-and-drop events. Events can also be shared via SMS or social media like Twitter and Facebook.

Here’s a quick rundown that shows exactly how the calendar works. Click here if you can’t see the video.

The Grid is a universal app designed for both the iPhone/iPod touch and iPad/iPad mini. It can be downloaded now in the App Store for free. With in-app purchases, users can unlock the midnight version or the pro version that features reminder support and a hybrid week with a list view.
