Clear is a minimalist iphone only to-do list app with an engaging touch interface: Swipe, pull, and pinch to work with your tasks. Tasks are color-coded in a heat map so you know which are the most pressing.
Pull down to create a task, swipe to complete it, and pinch to change to a different list. That’s it.
Unfortunately Clear does not have an Android app. However, a near perfect clone of Clear has been released for Android. This app goes by the name of koalcat’s Clear, this app is free and can be downloaded from android market(link).
I have been using this app for quite a while, below are some screenshots from my android :=)
Hope this helps :)
