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 review sentiment: WebMO Premium at 67% against Kaplan MCAT's 5%. WebMO Premium also leads on iOS requirement (12.0 vs 15.6). Kaplan MCAT's advantage is price (Free vs $4.99) and update cadence (every 3 months vs every 17 months). On ads, in-app purchases 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
Kaplan MCAT is free to download; WebMO Premium costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Kaplan MCAT holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Kaplan MCAT has 264 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of WebMO Premium's written reviews are positive against 5% of Kaplan MCAT's, so the app with the better star average is not the one people write more warmly about.
WebMO Premium ships an update every 17 months, Kaplan MCAT every 3 months. The most recent releases landed on October 7, 2026 and October 15, 2026 respectively.
