The document describes an augmented reality app called ARGrapher that was created to help middle school students better visualize and learn 3D geometry. User testing of an MVP found that students found the app easy to use and enjoyed being able to customize and move virtual 3D objects in real world space using augmented reality. Feedback from users suggested making the app more fun and that phones are often not allowed in schools. The creators learned that they need to divide the work between team members and not assume their own experiences match those of the intended users.
