Kepler Drift

Shape systems. Defy gravity.

A 3D orbital-physics sandbox for iPhone. Slingshot planets, tilt their orbits, hold them stable — then fly through real star systems and galaxies, on screen or floating in your room with augmented reality.

Physics

Real orbital mechanics

Newtonian n-body physics in AU, solar masses and years (G = 4π²). Every orbit you build is really being computed — and can really go wrong.

Play

Challenges & a daily orbital

Hold an orbit for three revolutions, rescue a runaway ice world, lock two planets into a 2:1 resonance. A new daily system for everyone, validated solvable before it's shown.

Explore

Twelve real star systems, twelve galaxies

From the Solar System with its moons to TRAPPIST-1 and Kepler-90; from the Milky Way to Andromeda and the Cartwheel. Real masses, orders and tilts.

AR

Float it in your room

Place a living star system or a galaxy in front of you and walk your eyes around it — a planetarium in your hand.

Feel

Haptics and sound as one

Stable orbits pulse in your hand; unstable ones warble. Haptics and audio are driven from the same physics values.

Fair

One purchase, nothing else

The physics, the daily challenge, the first challenges and five AR sessions a day are free. One optional purchase unlocks everything. No subscription, no ads, no accounts, no tracking.

Adults only (18+). Kepler Drift is intended for adults and must not be used by children. The augmented-reality mode overlays a virtual scene on the live camera image: stay aware of your surroundings, use it standing still in a clear space, never while walking or driving, and stop if you feel unwell. The camera image is processed on the device only and is never stored or transmitted.
