Set your initial conditions and just watch the system evolve or intervene to decide the fate of the particles!
- N-body physics simulation with pure gravitational interactions between particles.
- Create walls particles can't trespass. Watch them bounce off.
- Collision policies: physically realistic elastic collisions, mergers or no collisions at all.
- Configurable particle colorus.
- Configurable background image/colour.
- Configurable gravity strength.
- Configurable particle masses and sizes.
- Add friction to the mix!
- Accelerometer support.
- Repulsive forces.
- Shoot particles of different sizes.
- Repulsive particles.
- Static particles.
- Simulation area: screen or big area with panning and zooming.
- Enable or disable the central black hole which exerts a neat attractive force towards the center.
-Enable or disable particle trails (disable to improve performance).
-Modify simulation velocity in real time.
-Particle-Particle and Particle-Mesh simulation methods. Use first for accuracy, use second for performance.
-Display grid densities as background in Particle-Mesh method.
Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.Download F-Droid
