Pocket Galaxy: Space Sandbox

Drop a planet into empty space and watch gravity take hold of it.

Pocket Galaxy is a 3D gravity sandbox where you place planets, stars and moons and then watch them orbit under real, physics-based simulation. Arrange a solar system exactly how you like it, then take it apart: heat worlds until they glow, freeze them solid, hurl asteroids, fire solar rays and set off chain reactions.

There are no levels and no timers. The sandbox is the whole game, and the only clock is the one gravity keeps.

What you can do
• Sculpt entire solar systems from a near-infinite variety of worlds
• Tune each world's gravity, size and orbit, even flip gravity to repulsive
• Reach for cosmic tools: asteroid storms, solar rays, ice rays and explosions
• Unlock new world and star types as you experiment
• Discover procedural worlds, gas giants and glowing stars
• Track your creations, and how life develops, in the Planet Journal
• Save, load and screenshot your universe to share

Relaxing and powerful at once, Pocket Galaxy turns real orbital mechanics into a toy box. Build a calm, life-bearing system, or smash it to particles; there is no wrong way to play it.

This is the full paid version. No ads, no in-app purchases, no interruptions. Pay once and own the whole universe.
