|A hydrogen sulfide probe, (randomly selected from my pile|
o'magazines.) Took me a bit to draw this.**
Using the free code provided to me, I downloaded a copy from the App Store and set to work fiddling with it; it's fairly intuitive and really doesn't take much to get started drawing structures. Even though there isn't (yet) the ability to use the ACS stylesheet, the structures still look pretty nice. (Thankfully, the atom labels are not in Times New Roman.) It's really nice to have a "clean" function (the broom icon).
As Andre the Chemist has mentioned, there is no text box, so it is difficult for the organic chemist to type in reagents above the arrow. Also, there are not a number of desirable R groups available to label molecules, including N3 for the molecule in the image above or "OR" for etheric R groups. (I assume that all these functions are coming in future releases.)
I was also surprised at the relative inability to communicate one's ChemDraw for iPad structures to the rest of the world. You can't save your structures as an JPEG image, nor can you Tweet them.*** You can use Perkin-Elmer's "Flick to Share" network, but it seems odd to create pretty much an entirely new social network (with its own login/password combo) to e-mail around ChemDraw files. You can definitely e-mail the ChemDraw files to yourself, which I suspect is the main way that people will transfer them.
At the moment, this application seems to be a work-in-progress; as I have said, the desktop ChemDraw is such a mainstay of chemists that it seems obvious that this app will improve over time, and the apparent imbalance between the desktop program and the app will disappear. It will definitely be well-used, I suspect, by chemists who want to draw simple structures on the go, so that they can fill in detail work later. For now, I think that it serves as a good, basic tool to communicate structures with your iPad.
Note: Other than a free download code****, Chemjobber has received and will receive no financial incentive for writing this review.
* If I had a nickel for every time I heard, "ChemDraw is of the devil!"
** 7 minutes, to be exact. 3:30 on my desktop ChemDoodle.
*** You can screenshot your files, which is what I did above. Also, the number of folks who Tweet structures into the wild is probably quite small.
**** The app costs $9.99.
