Realmac Software has released an update to Clear, its minimalist list making app for the iPhone and iPod touch. First released in February, Clear is designed to allow users to quickly and easily manage simple lists of tasks and other items with a unique, gesture-based user interface. Version 1.1 adds support for undoing actions by shaking the device and basically removes the character cap on items. The update also introduces new “Secret Themes” for users to discover; the original version offered a special Tweetbot bonus theme for users of that particular app, it’s unknown whether these new secret themes follow the same patter or are hidden in some other way. The update also adds a number of smaller tweaks and fixes, including an option to display the iOS status bar, improvements to item creation, new UI elements and improvements to readability in low-contrast themes. Clear requires iOS 5.0 or later and is available from the App Store for $1.
