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 (, an international repository of biological molecules and their 3-D structures, or NCBI's PubChem (, 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.

Fond of this app

I have a soft spot for this app.

When iPads first came out, this app was on screens in stores all over the place, demonstrating the graphics and interactive touch mechanism of a device we now take for granted.

Plus, the developer offers it for nothing (unlike a lot of app developers now, who are angling for an app that will earn big bucks).

Nice 3D renders

You can search and add your desired molecule and spin it in 3D to see its structure. Atoms are colour coded and there is a legend too. Very nice.

I would only add that you need to be able to sort the list of molecules you have acquired or at least have them displayed alphabetically to make it more useful.

Developer pay attention

This needs to be updated asap
