Space Crash Simulator is the first mobile app with Smoothed Particle Hydrodynamics (SPH) for planetary collisions. Watch as planets collide and break apart in real time, with a robust simulation running a decent number of particles for a detailed, physics-based simulation.. The simulation lets you jump straight into high-energy collisions or customize initial conditions in Setup Mode. Adjust parameters like particle count, planet velocity, and collision accuracy to create your own collision scenarios. SPH simulations are notoriously resource intensive but settings like particle count, accuracy and timescale can be adjusted to allow even weaker devices to run it.
Version History - Fixed protoplanetary disk textures bug - Added an option to use your own images as planet textures. Scroll through the planet textures and after Pluto you will now find a "Custom" texture. Click on the blue text and you will be able to select your own image. - Fixed a touch control bug in setup - Updated native libraries to support 16 KB memory page size. - Unity security fix 0.32 10/26/2025 - Added an option to use your own images as planet textures.

If you make them spin too hard they'll fly apart however. - Fixed overlapping UI - Bug fixes 0.26 06/26/2025 - Added Mercury, Saturn, Yellow Star and Blue Star textures - Replaced the "Texture" selector by a "Material" selector, you can now set all planet materials with it, but also a black hole (single particle with much higher mass) and the new glowing star materials - Added "Spin" controls to make planets spin at a a velocity and direction of your choice.

That should give you more control when simulating with higher particle counts. The remaining stutters are due to the heaviness of the computations and unavoidable. - Added black holes. Reduce the particle count of any planet to 1, and you'll be able to increase the particle mass to a very high number, creating a black hole - Other bug fixes 0.15 03/12/2025 - You can now add black holes. Just reduce the particle count of any planet to 1, and you'll be able to increase the particle mass to a very high number, creating a black hole - Updated lava effect (shockwave) - Fixed bug with proto-planetary disk not having initial spin - Other bug fixes 0.14 03/12/2025 - You can now add black holes.
