GearLab vs Mechanism

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.

Most "learning" apps teach you trivia. Mechanism teaches you how things actually work — and proves it by making you build the thing, not just read about it. Every lesson follows the same rule: try it before you're told. Wire lemons into a real circuit and watch a bulb light up. Drag pins until a lock cylinder turns. Spin two meshed gears and feel speed trade for force. Drag a pin across three overlapping rings until it lands on the exact spot GPS would find. You guess first, then the app tells you why you were right or wrong — not the other way around. WHAT'S INSIDE • 10 interactive mechanisms across 4 areas: Electricity & Circuits, Radio & Signals, Mechanisms, and Everyday Physics • Hand-built interactive diagrams for every hero lesson — not stock illustrations, not video, things you actually manipulate • A "try it yourself" step on every lesson — a real, physical follow-up you can do with things already in your house • Streaks, XP, and a rank system that tracks real progress, not just days opened • Shareable proof cards for what you just learned • Narration on every step, on by default, with a one-tap mute WHY IT'S DIFFERENT Most micro-learning apps are general trivia — pop culture, random facts, a little of everything. Mechanism only does one thing: the actual mechanics behind objects you touch every day. A lemon battery. A pin-tumbler lock. A capacitor flash. Bluetooth's frequency hopping. GPS trilateration. Real mechanisms, explained by making you build them, not by handing you a paragraph to skim. New mechanisms are added regularly.
