I have been on a search for the right "to-do list" app ever since I got my smartphone. I am a obsessive paper-based to-do list maker, but have yet to find just the right app to convert my physical list into a digital one. Every time I go to the Productivity section of the App Store, I get excited to download the latest list maker–but inevitably end up disappointed by the feature-heavy interfaces that make adding a to-do item not worth the effort. So, when I stumbled across the to-do list app: "Clear" on a design blog a couple months ago, I got very excited. Although, the user interface received much scrutiny for breaking two fundamental design rules (according to Fast Company): "Visibility (also called perceived affordances or signifiers)" and "Discoverability: All operations can be discovered by systematic exploration of menus," it provides for a much cleaner, simpler experience. The app uses all gestural interactions, which are now becoming just as commonly recognized as pointing and double-clicking with a mouse. To understand how the user would interact with this newer gestural-based interface, Juan Sanchez, Clear's Designer, used paper origami to mock-up the design. Here are some examples from Fast Company Co.Design article: "Using Origami to Mock Up Ingenious Gestural Interaces," of how Clear (on the left) and his other app, Path (on the right), work:

I will definitely be using this helpful, paper origami technique the next time I am tasked with designing a gestural based user interface, and maybe the refreshing simplicity of "Clear" will be enough to convert my paper to-do list into a beautiful digital version.
