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

Getting ready to apply to med school is hard enough. Keeping track of all the things you need to do, what progress you have made, and importantly how it ties together is super important--so we created the Premed App, designed to help you do just that. One big difference between this app and others is that we focus on narrative, something most apps and trackers do not. From our experience working at some of the top Medical Schools in the world (including Harvard, Stanford, and others) we have come to see that the most successful applicants are those that are intentional early on about what they do and why they do it. Our app helps make that thought process easy. If you have suggestions for features or changes, we would love to hear from you!

Verdict

The call

The clearest difference is rating: Premed App at 5.0 against WebMO Molecule Editor's 4.0. Premed App also leads on in-app purchases (none vs 2) and update cadence (every 9 days vs every 3 months). WebMO Molecule Editor's advantage is ratings volume (40 vs 1) and device support (3 vs 1). On price and ads there is nothing between them.
