Atomizer AR vs Chembook

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.

Chembook is an offline chemistry reference built around things you can turn, step through, and take apart. REACTION MECHANISMS IN 3D Step through 128 reaction mechanisms frame by frame, with curved electron-pushing arrows drawn on the actual atoms. Explore quantum-optimized structures alongside teaching models of the steps between them. Switch between the 3D model and a clean 2D skeletal depiction. ADVANCED TOPICS Explore six interactive lessons: collision theory, potential energy surfaces, Woodward–Hoffmann rules, crystal field and Jahn–Teller effects, Walsh diagrams, and band theory. Follow reaction trajectories across energy landscapes. Change molecular geometry to see orbital energies shift, explore spin and distortion, and watch discrete energy levels become bands. ATOMIC & MOLECULAR ORBITALS Rotate orbital isosurfaces in 3D, from s, p, d and f atomic orbitals to computed molecular orbitals. Explore their shapes, nodes and wavefunction signs. SPECTROSCOPY REFERENCE 1H and 13C NMR shift tables, IR and Raman bands, mass spectrometry and UV-Vis, with tappable reference entries that place peaks on a live spectrum. Includes an interactive n+1 splitting-tree tool. MOLECULAR DYNAMICS LAB Run interactive molecular simulations on your device. Explore argon, water and ionic systems, adjust temperature and density, and watch molecular motion and the radial distribution function update as the simulation runs. STRUCTURES & CONFORMERS Chair flips, anomers, amino acids, unit cells and framework solids in 3D, with a Ramachandran plot and potential-energy scans you can drag. PERIODIC TABLE All 118 elements with trends, a comparison view and detailed properties. QUIZ Seven modes: periodic table, compound hunt, reaction mechanisms, spectra identification, vibrational mode matching, nomenclature, and amino acids. BUILT FOR OFFLINE STUDY All reference content, lessons and visualizations work offline. No Chembook account, no sign-in, no analytics, no ads and no personal data collection. Your notes and study progress stay on your device. An internet connection is needed for purchases and restores. FREE AND PRO 20 core reaction mechanisms, the full periodic table, all spectroscopy reference, orbitals, structures, and the molecular dynamics lab are free. A single one-time purchase unlocks the remaining 108 mechanisms, all six Advanced Topics lessons and unlimited quiz play.
