ChemDoodle Mobile is the iPhone and iPad companion to the popular chemical publishing desktop application, ChemDoodle. ChemDoodle Mobile is a calculator for drawn organic structures. There are five main windows: Draw, 3D, Calculate, Spectra and Help. The Draw window shows a typical ChemDoodle sketcher, where you can draw and store your structures. The 3D window allows you to view the drawn molecule in 3D. The Calculate page calculates properties and the Spectra page simulates NMR spectra. All spectra are interactive. The Help page contains a thorough help guide.

You must buy the desktop version to use this app.

Grumpy Old Hepcat

"The guest account is disabled so as to provide better service to our paying customers."

Is this an end-run around the 30% fee Apple charges developers? More likely the devs did not plan for the amount of traffic a free chemical drawing app would generate.

Zero stars for an app that does nothing.

New update screwed up


One of me favorite app until the last update. Because now you have to be logged in (have a paid expensive account in order to view H-NMR) I would mind paying 5.99 for that option not an
expensive account (for a student).

Best chemical drawing tool for phd


This is much better than anything else out there, I love using chemdoodle!
