LAMMPS on your phone/tablet! Learn about atomic physics or show your research to other people. Gain intuitive visual understanding of how atoms behave in liquids, solids and gases. With Atomify, your phone/tablet is transformed into a physics simulator allowing you to study atoms and molecules building up everything on this planet. In Atomify you are in charge of the universe. You are God. Perfect for anyone wanting to understand physics at the atomic level. The simulations are performed with the high performance molecular dynamics code, LAMMPS[1]. Developed by Anders Hafreager and Svenn-Arne Dragly (PhD candidates at the University of Oslo). Atomify LAMMPS is open source (GPLv3) and the source code can be found on GitHub[2].

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: Atomify at none against Quantum's 6. Atomify also leads on iOS requirement (8.0 vs 26.0). Quantum's advantage is update cadence (every 5 weeks vs every 7 months) and rating (4.8 vs 4.5). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Quantum sells 3 one-off in-app purchases. Atomify 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 8, so its average is the more settled of the two. Written reviews point the same way: 75% of Atomify's written reviews are positive against 86% of Quantum's.
Atomify ships an update every 7 months, Quantum every 5 weeks. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
