Molecules is an application for viewing three-dimensional renderings of molecules and manipulating them using your fingers. You can rotate the molecules by moving your finger across the display, zoom in or out by using two-finger pinch gestures, or pan the molecule by moving two fingers across the screen at once. These structures can be viewed in both ball-and-stick and spacefilling visualization modes.
New molecules can be downloaded from either the RCSB Protein Data Bank (http://www.rcsb.org/pdb), an international repository of biological molecules and their 3-D structures, or NCBI's PubChem (http://pubchem.ncbi.nlm.nih.gov), a public database of compounds. Molecules can be downloaded directly to your handheld device and stored there for later viewing.
Custom molecular structures can be downloaded to the application via iTunes file sharing, or through the use of custom URL formats. For more details, please visit our website.
Molecules is a BSD-licensed open source project.
- Added support for the new Retina iPad to the rendering engine and artwork.
- Added a color key for elements to iPad interface.
- Slightly improved rendering fidelity on iPhone 4S and iPad 2.
- Fixed a few minor rendering glitches.
Ratings and Reviews
I'm a high school chemistry teacher, and this app would be a lot more awesome if you guys could add some sort of structural annotation key (i.e., what are all of these atoms we're looking at?) and/or a chemical formula to the page. Surely that information is stored on the database pages your app pulls from, and so could be integrated into the GUI? It looks like all of the same sorts of atoms are of similar color across models, which is great, so now all we need is a little guide people (e.g., students) could reference at will to remind them what the atoms are.
Otherwise, this is a fantastic app! Great work!
Still not fixed as of June, 2013. It cannot even use files previously saved via iTunes! Anyone have a viable replacement to suggest?
This worked great on the iPad 2 two months ago. The PubChem access is awful: e.g., ethanol is there, but this app cannot even find it! Finding simple substances like water, methane, ammonia, formaldehyde, hexane, ethanol, and so on worked great before. Now they either do not show up at all or are hidden as bizarre numbers that make no sense even to a chemist. And you cannot even add the common name if you get lucky and find the molecule you want. As a chemist, I am very disappointed with this serious decline in capability. I will be looking for a substitute. Please fix this screwup!
Almost worthless now. Please fix the blunders and make this usable again!
Like the visual but need more options
The visual is really helpful and the addition of the color key for the atoms was helpful, however, we really want an option to label the atoms in the 3D model, the ability to turn on/off that option, and also an update to have an option or link to view molecule diagrams.
Other than that I have no complaints.
With Family Sharing set up, up to six family members can use this app.
