About

KIGAKU

Features
Read full description

KIGAKU is a visual learning app that teaches how machines work by letting you move them. How do teeth change speed and torque? Why can a pulley or screw turn a small force into a large one? Move a slider and the mechanism responds at once, with its results updating alongside. The formulas in your textbook connect to motion you can see. [Transmit power] - Gears: how tooth counts set speed and torque - Belt drive: pulley diameter and speed ratio - Planetary gear (new): hold a different part for reduction, overdrive, or reverse [Multiply force] - Pulleys: rope count, required force, and pull distance - Lever: fulcrum position and balance of moments - Screw: turning torque into thrust, and efficiency - Hydraulics: Pascal's principle and piston area ratio [Convert motion] - Linkage: four-bar paths and Grashof's condition - Cam: shapes that turn rotation into lift - Crank: converting rotation and reciprocation - Geneva drive (new): turning steady spin into stop-and-go steps - Robot arm: joint angles and tip position [Features] - A sheet explaining the formulas and principles of each mechanism - Learn without an internet connection - Dark and light modes - Available in 74 languages - Free, with banner ads only at the bottom of the screen Great for students of mechanical engineering and robotics, anyone curious about how machines work, and teachers looking for classroom material.

Verdict

The call

The clearest difference is price: KIGAKU at Free against Mechanical Engineering Lab's $12.99. KIGAKU also leads on iOS requirement (15.0 vs 17.0). Mechanical Engineering Lab's advantage is ads (none vs shown). On update cadence, in-app purchases and device support there is nothing between them.
