Atomizer AR turns your iPhone or iPad into a portable quantum chemistry lab. Visualize atomic and molecular orbitals in 3D, render electron density clouds, and step into immersive WebXR augmented reality where molecules sit on your desk at real-world scale. — WHAT YOU CAN DO — • Explore atomic orbitals computed from real hydrogenic wavefunctions: 1s, 2p, 3d, 4f and beyond, with adjustable shell glow and Bohmian trajectory animation. • View any molecule's molecular orbitals (HOMO, LUMO, intermediates) computed via PySCF on the cloud, then rendered as interactive isosurfaces. • See ball-and-stick models in WebXR augmented reality. Tap "View in AR", point at a flat surface, place the molecule on a table, then pinch to scale and drag to rotate. • Pair your phone with the desktop using Atomizer Remote: enter a 4-letter code, then tilt your phone to control the on-screen molecule with your gyroscope. Live preview streams back to your phone in real time. • Browse 40+ molecules — water, glucose, caffeine, benzene, ammonia, ethanol, methane, sulfuric acid and more — with energy diagrams, dipole arrows, lone pairs (VSEPR) and MO correlation diagrams. • Calculate molar mass live from any chemical formula, including parenthesised groups like Ca(OH)₂ and (NH₄)₂SO₄, with per-element breakdown. • Balance equations, run stoichiometry, sketch molecules in 2D, and explore reaction pathways. — SUBSCRIPTIONS — Free: 5 molecule renders per period. All calculator tools and full periodic table. Californium Pass — $2.99/month. 50 renders monthly, priority compute queue. Einsteinium Pass — $6.99/month. Unlimited renders, GLTF export for AR/3D printing, protein visualization, priority support. Auto-renews unless cancelled at least 24 hours before the period ends. Cancel anytime in Settings → Apple ID → Subscriptions. Subscriptions sync across iPhone, iPad, and electronvisual.org.

Verdict

The call

The clearest difference is in-app purchases: Structure Viewer at none against Atomizer AR's 4. Structure Viewer also leads on iOS requirement (11.0 vs 15.2). Atomizer AR's advantage is device support (6 vs 3). On price and ads there is nothing between them.
