Ever since it was unveiled during the iWorld (a.k.a. "Macworld") conference last month, iOS users have been waiting to get their hands on "Clear," a to-do list app that takes advantage of iOS' diverse multi-touch features. Yesterday, Clear (App Store link), which is developed by Realmac Software and Impending, was released to the iOS App Store for a special introductory price of $0.99.

The app focuses on providing a clean user interface with as few buttons as possible because a majority of functions are accessible via gestures. The app includes some basic settings, as well as the ability to theme to-do lists. Alongside this, special themes can be unlocked if you have purchased other specific apps from the App Store. For example, if you purchase the app Tweetbot, a new theme for Clear will be unlocked that looks similar to the design of Tweetbot.

If you've bought the app, let us know what you think of it in the comments below!
