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.

PDB Viewer turns your phone into a molecular microscope. Search the entire Protein Data Bank and over 200 million AlphaFold predictions, then explore any protein, virus, drug, or DNA structure in interactive 3D — free, with no account, no ads, and no sign-up. WHERE THE MOLECULES COME FROM • RCSB Protein Data Bank — 200,000+ experimentally determined structures • AlphaFold — 200M+ AI-predicted protein models • SWISS-MODEL — template-based homology models • PubChem and ChEMBL — millions of drugs and compounds • Crystallography Open Database — small-molecule crystals • NCI/CADD resolver — type a chemical name and get a 3D model Every source is free and needs no API key. You can also open your own .pdb and .cif files. WAYS TO SEE IT • Five representations: wireframe, ball-and-stick, space-filling (CPK), cartoon/ribbon, and a smooth molecular surface • Color by element, chain, secondary structure, rainbow, or AlphaFold confidence (pLDDT) • Biological assemblies: rebuild an entire icosahedral virus capsid from a few deposited chains • NMR ensembles: overlay every model in the bundle to watch a protein flex • Automatic secondary-structure detection MADE FOR TOUCH • Rotate, pinch-zoom, and pan with smooth native rendering • Tap any atom to see its element, residue, and chain • Recently viewed structures are cached, so they reopen instantly and work offline For students, researchers, teachers, and the simply curious. PDB Viewer makes structural biology beautiful and accessible. Structures are provided by their respective databases. PDB Viewer is independent and not affiliated with or endorsed by the RCSB PDB, EMBL-EBI, or AlphaFold.
