About

Space Crash Simulator

Experience realistic planetary collisions with a powerful physics engine. Customize your own cosmic events by adjusting particle count, velocity, and accuracy, or jump straight into high-energy impacts. This app offers a detailed, physics-based simulation for educational or entertainment purposes.

Highlights
  • Smoothed Particle Hydrodynamics (SPH) simulation
  • Real-time planetary collisions
  • Customizable simulation parameters
  • Setup Mode for scenario creation
  • Adjustable particle count and accuracy
  • Physics-based detailed simulation
Features
Read full description

Smash worlds together and watch them shatter, merge, and melt, driven by real physics, not pre-made animations. Every planet is made of thousands of interacting particles, so every collision is computed live and no two impacts ever look the same. Build your own scenario in Setup Mode: place up to 8 bodies, set their size, density, spin and velocity, then let gravity do the rest. Or dive straight into a head-on collision and watch the debris glow, cool, and form a crust. - True particle physics (SPH), the first of its kind on mobile - Molten impact zones: heat, lava, and cooling crusts - Give planets rings or shred a moon into one with tidal forces (Roche limit) - Protoplanetary disk and colliding-galaxies modes - Black holes that tear planets apart - Custom planet textures from your own photos - Runs on everything: tune particle count, accuracy, and timescale to your device

Verdict

The call

The clearest difference is rating: Aphelion at 4.9 against Space Crash Simulator's 4.5. Aphelion also leads on review sentiment (100% vs 81%) and update cadence (every 2 days vs every 5 days). Space Crash Simulator's advantage is ratings volume (723 vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.
