Many concepts in chemistry can be difficult to grasp without being able to really see what’s going on! Learning and understanding how electrons orbit an atom is precisely one of those topics. Designed by professional educators, Orbitalz is the world’s premiere atomic orbital visualization app. Using high definition, three-dimensional models, Orbitalz allows the user to view and manipulate every type of electronic atomic orbital for a hydrogen atom. A perfect textbook companion, this app allows the user to rotate and view the shapes of the orbitals from any angle as well as superimpose the orbitals within a family to see how their positions in three dimensions interact with each other. Orbitalz includes the s orbital, three p orbitals, five d orbitals, and seven f orbitals. If you’re a chemistry student or just interested in how atoms are put together, then Orbitalz is for you!

WebMO Premium is equivalent in functionality to the free 'WebMO' app in conjunction with the 'WebMO Premium' in-app purchase. This paid version is provided for convienence for volume purchases. WebMO allows users to build and view molecules in 3-D, visualize orbitals and symmetry elements, lookup chemical information and properties from external databases, and access state-of-the-art computational chemistry programs. WebMO is recommended for students and faculty in high school, college, and graduate school who desire mobile access to molecular structures, information, and calculations. WebMO capabilities include: - Build molecules by drawing atoms and bonds in a 3-D molecular editor, or by speaking the name (e.g., “aspirin”) - Optimize structures using VSEPR theory or molecular mechanics - View Huckel molecular orbitals, electron density, and electrostatic potential - View molecular vibrations - View point group and symmetry elements of molecules - Lookup basic molecular information, including IUPAC and common names, stoichiometry, molar mass - Lookup chemical data from PubChem and ChemSpider - Lookup experimental and predicted molecular properties from external databases (NIST, Sigma-Aldrich) - Lookup IR, UV-VIS, NMR, and mass spectra from external databases (NIST, SDBS) - Capture high-resolution molecular images - Save and recall molecular structures locally - Export and import structures via email WebMO is also a front-end to WebMO servers (version 14 and higher): - Supports Gaussian, GAMESS, Molpro, MOPAC, NWChem, ORCA, PQS, PSI, Quantum Espresso, VASP, Q-Chem, and Tinker computational chemistry programs - Submit, monitor, and view calculations - View formatted tabular data extracted from output files, as well as raw output - Visualize geometry, partial charges, dipole moment, normal vibrational modes, molecular orbitals, and NMR/IR/UV-VIS spectra

Verdict
The clearest difference is price: Atomic Orbitalz at $0.99 against WebMO Premium's $4.99. Atomic Orbitalz also leads on update cadence (every 8 months vs every 17 months). WebMO Premium's advantage is review sentiment (67% vs 50%). On ads, in-app purchases, monetization model and device support there is nothing between them.
