The Smart Camera for Math
Numo-- The mobile app that teaches students to understand math homework. Users take a picture of any problem and Numo explains how to do it step-by-step. Free to use, but students complete a monetized survey in-app before they view answers. Students from elementary school to university learn math with Numo.
