Thank you for all the positive feedback! Please rate ChemDoodle Mobile 5 stars so we can continue to provide you with new and free features.

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.

Customer Reviews

Better and better

I purchased ChemDoodle about a year ago and I continue to be amazed by how much I get. This mobile app has been incredible and allows me to easily show molecules to students and generate NMR on the fly. I love the full 3D graphics. Best update yet, keep it up!

You must buy the desktop version to use this app.

"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).
