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 call

The clearest difference is rating: Organic Nomenclature at 4.7 against WebMO Molecule Editor's 4.0. Organic Nomenclature also leads on review sentiment (88% vs 60%) and ratings volume (660 vs 40). WebMO Molecule Editor's advantage is update cadence (every 3 months vs every 21 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Organic Nomenclature holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Organic Nomenclature has 660 ratings behind it against 40, so its average is the more settled of the two. Written reviews point the same way: 88% of Organic Nomenclature's written reviews are positive against 60% of WebMO Molecule Editor's.

UpkeepUpdate frequency

Organic Nomenclature ships an update every 21 months, WebMO Molecule Editor every 3 months. The most recent releases landed on October 29, 2026 and October 23, 2026 respectively.
