• NEW: Added Compute function for smooth replay (including rewind and slow-motion) on weak devices • NEW: Planetary rings! Give any planet a ring in Setup Mode — tilt it, resize it, watch it orbit, catch the planet's shadow, and rain glowing debris onto the surface. Or shred a moon into a ring with the tidal break-up action. • New Extras menu in setup (rings & orbit helpers) • Enter values directly without sliders • Graphics improvements

Space Crash Simulator is a mobile application that uses Smoothed Particle Hydrodynamics (SPH) to simulate planetary collisions in real time. It allows users to witness and create detailed, physics-based cosmic events.
Key features include a robust SPH simulation engine for realistic planet collisions, a Setup Mode for customizing initial conditions like particle count and velocity, and adjustable settings to optimize performance on various devices.
Yes, the app is free to download and offers in-app purchases. It also includes advertisements.
Yes, you can customize initial conditions in Setup Mode. This includes adjusting parameters such as particle count, planet velocity, and collision accuracy to create your own unique collision scenarios.
The app is designed to be accessible on a range of devices. Settings like particle count, accuracy, and timescale can be adjusted to allow even less powerful devices to run the simulation effectively.
