What good is building a structure if you can't paste it into other programs? The interface is reasonable. Mistakes are easily corrected and I really like the rotation feature. Being able to exchange structures with other programs would be a plus. ### 5/5 — Helpful, easy, perfect. *2009-09-27* I know not everyone studies chemistry, but for those who do, they should get this; this app rocks. It took me approximately 5 minutes to get to fully understand how everything worked, but once that was out of the way, I found the app really easy to use. The developer provides plenty of methods for getting your molecular drawings off the iphone which is a big bonus. The only thing that would make this app better would be if it could take a stab at naming your created molecule, now that would be cool. ### 4/5 — Great Start *2009-08-13* Very useful chem app. I wish the developer were easier to contact. The only real problem is that it does not count hydrogens when calculating molecular mass, etc. That needs to be fixed. I am also baffled by the ctrl gear button which appears to have no purpose. Anyway, this is an app that I have been waiting for for some time. Mimol was a nice stopgap, but this has a much more professional look and feel, and many more functions. I hope the developer keeps working on it because it could be a must-have science app with a few fixes/improvements. ### 2/5 — mmm *2009-08-03* This app is ok but would totally top the awesome scale if it were compatible with imole builder so that you could view your molecule in three dimensions. ### 3/5 — iMolDraw is a great start for a chemistry drawing app. *2009-07-28* Far better than the only other chemistry drawing app I'm aware of. It's terrific for quickly sketching out ideas or archiving structures for reference. The previous reviewer pointed out a big flaw: the program ignores hydrogen atoms when calculating MW. I wrote to the developer with some questions but have not received an answer. Maybe other users have figured these out. 1) Is there a way to move just a part of the molecule? For example, I can use the lasso tool to select a phenyl ring. I would like to move it out of the way of another group. Every time I try, I move the entire structure. 2) What is the function of the button with the little gear and the label CTL. It doesn't seem to do anything except change color. I also offered two suggestions that would improve the usability of iMolDraw. The program uses the MOL file format which is great for exchanging data with other chemistry programs. ChemDraw is, by far, the most popular chemistry drawing program for PCs and Macs. It can read and save MOL files but the default is its own CDX format. I wish iMolDraw could read CDX files directly. The developer also offers the free iMolServer for exchanging files between a PC and iPhone. I wish for a Mac version or the ability to import files directly from the iDisk. This program is a great start. I've been wanting a program like this ever since I had my Apple Newton. A few improvements and it will deserve 5 stars. ### 3/5 — Good for 2D stuff, has major bug *2009-06-23* Looks like a solid 2D drawing tool but can't calculate molecular wt correctly since it forgets to count the hydrogens! There is not a strucure clean up function so try to get it right the first time. ## Frequently asked questions about iMolecular Draw ### What can I do with iMolecular Draw? iMolecular Draw allows you to view, edit, and build molecules in 2D.
