Build your own universe, right in your pocket. Pocket Galaxy is a 3D gravity sandbox where you place planets, stars and moons, then watch them orbit under real, physics-based simulation.
Play god: heat worlds up, freeze them solid, hurl asteroids, fire solar rays and trigger explosive chain reactions, or nurture a planet and watch life begin.
