Android App Analysis and Review: WebMO, Developed by WebMO, LLC. Listed in Education Category. Current Version Is 2.3.1, Updated On 09/09/2025 . According to users reviews on Google Play: WebMO. Achieved Over 66 thousand Installs. WebMO Currently Has 384 Reviews, Average Rating 4.6 Stars
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 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, NMRShiftDB)
- 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 16 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
We are currently offering version 2.3.1. This is our latest, most optimized version. It is suitable for many different devices. Free download directly apk from the Google Play Store or other versions we're hosting. Moreover, you can download without registration and no login required.

I almost never write reviews, but I purchased the full version within a minute of using the free version. This app is incredible, allowing the user to determine the electrostatic potential and electron density for constructed molecules. These features are available for a molecule containing 9 or more atoms for the premium edition, which costs 4.99. Also, the periodic table is available for picking atoms in the construction.

Whole the UI is good, and the structure mechanics are okay, the auto-geometry cleanup does not accurately show the molecular geometry of even simple molecules. I attempted to draw a molecule know as mustard gas, or sulphur mustard, which is a toxic gas used in WW1, but the structure was not displayed accurately (Both Cl atoms are meant to occupy the same level/plane in the molecule, but that didn't happen). What I mean to say, is both sides of the molecule should be mirror images, not different.

I like this app. It automates the drudge of trying to look up a molecule in multiple databases. My only lingering wish is for a choice of molecule display modes. The ball and stick works OK, but sometimes you *want* electron clouds or simpler stick connections to be used instead. Certainly worth the price tho!

This game would have been five stars because it is so interesting and includes atom sizes. The only thing that takes away the fifth star is the fact that after a certain amount of time, it will start asking you to pay for the full version just to see the info of your molecule and other stuff. Other than that, fun game! :D

Absolutely love this app. Just a small feedback on the job submission. Not sure if it is a bug, but I used to be able to choose the computational engine I would like to run the job on, but now it's restricted to use Mopac. If the option to choose the computational engine is restored it'll be really great!

Cool app for visualizing MO's for undergrads, but, unfortunately, quite a lot of stuff has to be taken with caution: there're quite a few effects this app predicts quite poorly even for the simplest molecules: -VSEPR is applied in quite a few cases where it should be much less noticeable, like PH3, H2S and so forth, giving wrong angles and therefore wrong MO's; -Bond lengths for heavier atoms are also too short for some reason, trying to adjust them to the real numbers in turn results in very poor interaction of AO; -H2S has its positive charge on ithe sulfur, according to this app; -For an app, trying to apply MO method to construct the visual representation of molecules, it relies too heavily on valency, charge and so forth, poorly taking conjugation into account (at least with charged particles where charge is delocalized); -Switching between allyl cation and anion does not change the overall number of electrons! And, of course, the app thinks the molecule is not as symmetric as it really is (Cs vs C2v), but that's really closer to the previous point. Considering other apps get a few of these things right, I hope it'll be implemented here as well.

Great for on-the-fly molecular modeling if you need a level of theory to direct your imagination about a reaction scheme or more deeply understanding a structure, and also just plain cool to have a molecular modeler in your pocket. Definitely worth the premium upgrade to model larger molecules.

While a fun novelty for the curious the import could use a "Did you mean X" feature, seeing as anything other than the correct spelling will yield nothing.
