The double pendulum is a simple mechanical system that displays chaos. The motion of the pendulum arms can be complex and unpredictable, with even minute changes leading to very different trajectories. This app accurately simulates the physics of a frictionless double pendulum, so you can explore and enjoy the complexity and beauty of mechanical chaos.

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: Double Pendulum at none against Quantum's 6. Double Pendulum also leads on review sentiment (100% vs 86%) and iOS requirement (11.2 vs 26.0). Quantum's advantage is ratings volume (133 vs 2) and rating (4.8 vs 4.5). On price, ads and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. Double Pendulum asks for nothing beyond the download.
Quantum holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Quantum has 133 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Double Pendulum's written reviews are positive against 86% of Quantum's, so the app with the better star average is not the one people write more warmly about.
