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 rating: Kaemika at 5.0 against WebMO Molecule Editor's 4.0. Kaemika also leads on review sentiment (100% vs 60%) and in-app purchases (none vs 2). WebMO Molecule Editor's advantage is ratings volume (40 vs 1). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. WebMO Molecule Editor sells 2 one-off in-app purchases. Kaemika asks for nothing beyond the download.
Kaemika holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: WebMO Molecule Editor has 40 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 60% of WebMO Molecule Editor's written reviews are positive against 100% of Kaemika's.
WebMO Molecule Editor ships an update every 3 months, Kaemika every 6 weeks. The most recent releases landed on October 7, 2026 and September 20, 2026 respectively.
