Very easy and useful app

I was wondering to draw chemical structures for my research and this app is tremendously useful for me.
Thanks so much developers.

Very difficult to use

The GUI is not user friendly. Please have a look at ChemDraw and ChemDoodle and try to implement some of their features.

I got this app as it may

Cool Idea But Unresponsive

Maybe I need a more powerful iPad than a Mini, but I found it to be pretty unresponsive. I'd like to check back in a month or two when they've polished it up a bit and responded to customer feedback.
