View augmented reality model of physics and math concepts through your phone. You'll need a Merge Cube (downloadable from the internet). Click on different button to navigate to different topics. Click on View in AR to view the model. Hold the Merge cube so that your camera can see it well. Move the cube around until you see the model. Click on the buttons to interact with the model. Click the back button to get back to the info screens or to the main screen.

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: MARVLS at none against Quantum's 6. MARVLS also leads on review sentiment (100% vs 81%) and iOS requirement (11.0 vs 26.0). Quantum's advantage is update cadence (every 5 weeks vs every 8 months) and ratings volume (152 vs 35). On price, rating, ads and device support there is nothing between them.
