ForceForge 9 is a Grade 9 physics practice studio designed like a personal lab notebook. Students complete short workshop runs, explain their reasoning, and save LabNotes. When a mistake happens, a FixCard records the misconception and corrected rule to support long-term understanding.
GearLab
Read full descriptionHide full description
GearLab is an offline STEM education app for mechanical gears: animated simulations, system builder, engineering calculators, gear-type library, quizzes, challenges, and glossary. Designed for students and hobbyists to learn ratios, torque, and design concepts locally—no accounts or cloud. Not a substitute for certified engineering sign-off on real machinery.
