Experience the hidden world of particles Quantum is a real-time particle life sandbox for exploring emergent motion, artificial physics, and complex systems. Build fields with up to 10,000 particles, tune how classes attract or repel each other, and watch simple rules turn into flowing structures, swarms, or chaotic patterns. Why Quantum stands out: - Real-time particle simulation with four interacting particle classes. - Seamless 2D fields and perspective 3D volumes with touch rotation. - Rule editor for custom attraction and repulsion matrices. - Temperature, viscosity, solid/fluid edge behavior, and force tools. - Black hole and white hole tools for live interaction. - Save and load fields, rule sets, and color schemes. - P3 color support and vivid visual presets for generative art. Use Quantum as a physics toy, creative sandbox, teaching aid, or generative art lab. It is built for people who enjoy science, cellular automata, n-body systems, chaos, and beautiful simulations.

Verdict
The clearest difference is in-app purchases: G at none against Quantum's 6. G also leads on update cadence (every 8 days vs every 5 weeks) and iOS requirement (17.0 vs 26.0). On price, ads and device support there is nothing between them.
