Kinetic Cradle: ASMR Relax
Calm fidget & stress relief
Free · Designed for iPad. Not verified for macOS.
Control gravity with your fingertips. Swing a fully 3D Newton's Cradle on 12 planets, in 7 premium themes, with relaxing ASMR clacks. Your perfect desk companion.
Newton's Satisfying Cradle is a 3D physics playground where you control gravity itself. Pull a chrome ball, release it, and watch momentum travel through the chain with satisfying, relaxing clacks — then change everything. Swing the same cradle on the Moon for dreamlike slow motion, crank it to Jupiter for aggressive power swings, or float in zero-G aboard the ISS.
SWING ON ANY PLANET
Switch between 12 different gravitational environments in real time. Each planet's physics dynamically change how the balls swing, collide, and settle. Watch the same cradle behave completely differently on Mercury vs. the Sun.
FULL 3D, ANY ANGLE
Unlike flat cradle apps, this is a complete 3D model with dual V-shaped strings, a polished frame, and a physical base plate. Orbit the camera 360° around the cradle. Enable cinematic auto-rotate mode and watch it spin slowly like a jewelry display.
7 PREMIUM THEMES
Polished chrome, deep obsidian, royal gold, rose gold, crystal glass, glowing neon, and handcrafted premium wood. Each theme uses physically-based rendering with realistic reflections, clearcoat shine, and environment-mapped materials.
LIVE CAMERA BACKGROUND
Point your camera at your desk and watch the cradle appear to sit on your real table — a lightweight AR-style effect. Switch between front and back cameras. No photos or videos are captured.
AMBIENT EFFECTS
Surround the cradle with gentle snowfall, soft rain, glowing fireflies, drifting stardust, rising embers, or floating bubbles. Each effect uses GPU-accelerated particles with natural organic movement.
CUSTOMIZE YOUR PHYSICS
Adjust elasticity from rubbery absorption to perpetual-motion bouncy. Tune friction from smooth to heavy. Change string length from short to long. Make the simulation your own.
FREE-TOUCH INTERACTION
Touch any ball — not just the edges. Drag in any direction, and the correct group of balls follows naturally, respecting Newton's Cradle momentum transfer rules. Release with a flick to add velocity.
REPEAT MODE
Enable infinite zen mode: when the balls settle, they automatically restart with your last pull. Combined with auto-rotate, it becomes a mesmerizing desk companion.
REFINED SOUND & HAPTICS
Relaxing, ASMR-style collision sounds that scale naturally with impact velocity — loud clacks fade to whisper-quiet taps as energy dissipates. Five sound styles from deep and thick to bright and thin. Precise haptic feedback on every collision.
MULTI-LANGUAGE
Automatic device-language detection. Available in English, Turkish, Japanese, German, and Spanish.
DESIGNED FOR ALL DEVICES
Fully responsive on every iPhone from SE to 16 Pro Max. Supports iPad with adaptive 3D quality.
Newton's Satisfying Cradle is the desk toy you'd keep on your shelf — brought to life with real physics, premium visuals, and features rarely found in other cradle apps.
