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.
MARVLS
Explore quantum computing concepts through interactive augmented reality models. Requires a Merge Cube to visualize and manipulate topics like superposition and entanglement. Navigate through various educational modules to deepen your understanding.
- Augmented reality visualization
- Interactive quantum concepts
- Merge Cube integration
- Topics: superposition, entanglement, qubits
- Logic gates visualization
- Nuclear and electron spin models

Verdict
The clearest difference is rating: Quantum at 4.8 against MARVLS's 1.0. Quantum also leads on ratings volume (133 vs 1) and review sentiment (86% vs 67%). MARVLS's advantage is in-app purchases (none vs 6) and iOS requirement (18.0 vs 26.0). 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. MARVLS asks for nothing beyond the download.
Quantum holds the better App Store score, 4.8 against 1.0. 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. Written reviews point the same way: 86% of Quantum's written reviews are positive against 67% of MARVLS's.
Quantum ships an update every 5 weeks, MARVLS every 4 weeks. The most recent releases landed on September 23, 2026 and September 9, 2026 respectively.
