OneStone is personal decision making app that leverages the power of MCDAs (multi-criteria decision analysis) tables and simplifies the experience for the user. In three simple steps users can create powerful and accurate solutions to those pesky problems that seemingly have too many options. OneStone saves inputs and can make them available to others, thus building a powerful repository of ideas, suggestions, alternatives and templates. No other app has leveraged this concept before in such detail, which is why I created the prototype.

The prototype app was entirely designed in Figma, illustrations and icons were made in Adobe Photoshop and Illustrator.
Renders below were made using a mix of Adobe Photoshop, Illustrator, and Blender.

OneStone’s application and psychology theory are based from the book The Three Secrets of Wise Decision Making by the late professor Dr. Barry F. Anderson.
