Pendula - Chaos & Sound

A pendulum toy you can hear

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Pendula is a relaxing digital toy that turns the physics of the double pendulum into sound and light. A double pendulum is just a pendulum hanging from another pendulum — yet it moves in a way that never repeats itself. Scientists call it "chaos." Pendula draws that chaos as glowing light trails, and every time a pendulum crosses a string, it plays a gentle musical note. HOW TO PLAY - Drag a pendulum up with your finger and let go - Then simply watch and listen — no two runs are ever the same MAKE IT YOURS - Choose 1 to 4 pendulums, each with 2 to 4 links - Every combination creates a different dance and a different melody 9 SOUND MODES - Scale / Major / Japanese (koto) / Ambient / Minimal / Lo-fi / Bell / Arpeggio / Synesthesia (sound & color) - Every mode is tuned so the chaos always sounds pleasant KIDS' SOUND PACK (one-time in-app purchase) - Baby Mode: farts, pops, and other funny sounds that babies and toddlers love - Animal Mode: cute animal calls - One single purchase unlocks both modes — no subscription 4 VISUAL THEMES - Neon / Aurora / Sunset / Mono PERFECT FOR - Ambient visuals in waiting rooms, cafes, and shops - Winding down before sleep - Giggle time with your little ones - A first, beautiful encounter with chaos and physics LANGUAGES English, Japanese, Chinese (Simplified), Chinese (Traditional), Korean, French, Spanish, German, Portuguese, Russian, Arabic, Catalan, Croatian, Czech, Danish, Dutch, Finnish, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Malay, Norwegian, Polish, Romanian, Slovak, Swedish, Thai, Turkish, Ukrainian, Vietnamese Note: Pendula shows a small banner ad at the bottom of the screen.
