Ratings and Reviews

Nice app once it works


This app has a great interface, and a lot of potential. Unfortunately, it crashes when attempting to draw a structure, so it is not ready for use yet. Hopefully it will be fixed with an update, it looks like a very useful app for medicinal chemists.
A few hours later - OK, I can now draw molecules, although the learning curve is very steep and there is no help menu. Saving molecules is difficult, but if you are patient the calculations are quite good once you can get the molecule drawn and saved, and then re-open it. It seems hard to cut and paste the molecule and calculations to another program for displaying the results. Still a long way to go to be really useful, but a good start.
The calculations are superb, it's the drawing part that's hard, but it's a very useful app,if you can get used to the drawing conventions.
