Molecules

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!

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.

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!
