KinemathFormulas,
in motion.
Kinemath turns the big formulas of math and physics into beautiful step-by-step animations. Every symbol has its own color, and the same color moves on screen. Drag a slider and watch the numbers in the formula change.

See it, then you get it
From a² + b² = c² to time dilation, every proof is something you can watch.
Built for understanding
Not a formula sheet. A way to see why.
Color-linked symbols
Tap a symbol in the formula and the matching part of the animation lights up.
Live sliders
Change lengths, speeds and angles; the formula shows the numbers as you drag.
Step by step
Short captions walk through each idea. Pause, scrub, replay any step.
Present full screen
A clean full-screen mode for classrooms, projectors and AirPlay.
16 languages
Switch the app language instantly, from English and 中文 to العربية and हिन्दी.
