User reviews

Ridiculous

Long time ChemDraw user and thought I would try something free. This is horrible. Not intuitive at all. Just terrible to use. Don’t waste your time

aaaaa

特别好用

Amazing

Easy to use, perfect for organic chemistry

Really useful for Organic Chemistry

Great alternative for ChemDraw and works on iPad. Totally love it! It would be nice if it could predict proton and carbon-13 NMR peaks.

Not for specialised applications

Fantastic bit of app, but can’t do non-standard functionality.
I try adding Oxygen and it adds OH instead. I actually need to add OLi but can’t do it.
