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: QuantumNote at none against Quantum's 6. QuantumNote also leads on rating (5.0 vs 4.8) and iOS requirement (16.0 vs 26.0). Quantum's advantage is ratings volume (133 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. QuantumNote asks for nothing beyond the download.
QuantumNote holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Quantum has 133 ratings behind it against 1, so its average is the more settled of the two.
Quantum ships an update every 5 weeks, QuantumNote every 2 months. The most recent releases landed on September 28, 2026 and September 27, 2026 respectively.
