## GearLab 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.
