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.

Space Crash Simulator version 0.49
Updated At: 2026-06-29
Changes: - You can now add as many galaxies as you like
- Added set Roche button in setup
- replaced particle mass by planet density so you can make dense or loose planets irrespective of particle count
- Added real time lighting: planets have night and day sides, and cast shadows on each other
- You can now make planets much bigger by increasing their particle counts.
- Removed 2- and 3- body mode and replaced it with "Planetary Mode". In this mode you can add up to 8 planets in a scenario.
Space Crash Simulator version 0.36
Updated At: 2026-06-17
Changes: - Exposed some heat system parameters in the start menu
- Rebuilt simulation engine
- Real-time lighting
- New heat system
- Many fixes and optimizations under the hood
- More stable planets, starting in better equilibrium
Space Crash Simulator version 0.32
Updated At: 2025-10-24
Changes: - 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 Android 15 and 16 KB memory page size.
- Unity security fix
