Ratings and Reviews


Not very good, unfortunately

I'm a professional research chemist - I was looking for an app that would let me quickly draw structures so I can calculate m/z values for mass spectrometry when at the instrument. This app looks pretty slick at first, but it's super difficult and slow to draw even simple structures. As other users have pointed out, the on-screen sensitivity is pretty poor, and there aren't great drag and drop tools. Multitouch might be better utilised to have an "undo" button or to introduce heteroatoms. Hoping that this app can improve, because it could be a good contender for ChemDraw if a few things are improved.


Beautiful chemical structures!

Great app. Allows me to sketch all kinds of chemistry then paste it into Pages and Keynote. Just what I need on the train!

Perfect on the iPad 2 and mini that we also have in our house and the app is very responsive. I assume the retina iPads would work well with this app too.

Note to the developers - performance is awful on a first generation iPad. You might want to look into that if you plan to make an app that claims to support it.



There are many very basic scientific apps available, most of which contain very little information, and almost none of which actually allow any kind of useful interaction.

Elemental is by some way the most useful and practical scientific app I have found to date. If I were a chemistry or biology student, I suspect I would find the price of an iPad worth paying just for this app.
