The loop
One gesture. Nothing to learn.
No goals, no score, no ads. Just physics you can touch.
01
Press
The harder you press, the stronger the pull. Every particle bends toward the tip.
02
Hold
Stay still and the field gathers into a dense, vibrating core of energy.
03
Let go
The core releases in a shockwave of light and sound, then the matter drifts back.
21 signature atmospheres
Each one is a complete world.
Its own power, its own material, its own colors and motion. Event Horizon bends light around a black hole. Kintsugi mends the dark with veins of gold. Cryosphere freezes the field solid until you press hard enough to shatter it.
Accretion Disc
Invisible matter. Friction sets it ablaze.
Abyssal Drift
Stir the deep. It answers in light.
Tokamak Core
Plasma held in the wings of chaos.
Neon
Pure electric light adrift in the dark.
…and sixteen more: Solar Prominence, Kintsugi, Sacred Rosace, Zen Garden, Spectrum, Cryosphere, Kinetic Mandala, Non-Newtonian, Resonance, St. Elmo's Storm, Ferro-Lattice, Quantum Foam, Pele's Thread, Firefly Grove, Piezo Resonance, Saturn Ring.
The Studio
Build your own physics.
Combine any power with any material, then tune the force, the trail, the drag, the turbulence and the number of particles until the field behaves exactly the way you want. Save it as your own atmosphere.

When you put it down
It keeps living.
Standby
Stand your iPad or iPhone on your desk and the particles draw the time, then go dark at night.
Breathing
Follow a guided session — box, 4-7-8 or coherence — while the whole field breathes in and out with you.
Zen mode
Hide every control and leave nothing but the field.
Made for Apple Pencil
The tip is the force.
Gravion reads everything the Pencil can say. On iPhone, your finger does it all.
Pressure
Drives the strength of the pull, continuously.
Hover
The field leans toward the tip before you even touch.
Tilt
Tips the gravity of the whole field.
Double-tap
Switches power without leaving the canvas.
Squeeze
Opens the powers on Apple Pencil Pro.
Barrel roll
Rotates the field under the tip.
And it fits in your pocket
