The Mac version of Clear is built for use with Apple's new Mountain Lion operating system, letting users manage lists primarily via a gesture-based interface using their Mac's trackpad. (View the video below for a tour of the new app.) For example, to create a task, just start typing, then swipe right on the trackpad to complete it.
The launch of the desktop app is accompanied by an update to the original iPhone app; phone users can now switch between multiple lists by swiping between pages. They can also copy and paste multiple lines of text to create a "set" of to-do items. And the new iCloud support ensures users can shift between their phone and Mac without losing a beat.
Clear for Mac normally costs $15, but it's being offered at a discounted price of $7 for the first 24 hours. The Mac version is compatible with computers running OS X 10.8.2. Clear for iPhone costs $2, and is compatible with devices running iOS 6.0 or later.
