Ratings and reviews

I basically failed chemistry in highschool... I tried other molecule apps today, and this one is the winner. it takes a few minutes to get used to select, deselect, add bond, delete atom, but it is well worth it, especially for the shaping feature... I made a 5' adenosine monophosphate in about 2 minutes, and it looked really bad, but the shaping, pulled it together, and it looked like a textbook image... I was looking for Jmol mobile, and found something better! the ability to save molecules, and reload them is a winner. took less than an hour to make A,C,G,U and start making an RNA chain. awesome app. the zoom, pan, rotate controls are flawless, and I even made a short polypeptide with no performance issues... Chemists might find it lacking in features, but for the curious, and the learners, this app is priceless. 100!

My new favorite app! I'm no chemist, but this app is definitely super fun, educational, and feeds my creative interests in the subject. It's "hands on" approach has really taught me a lot about organic chemistry. My only complaint is the lack of other elements and tools. Aside from the hydronate tool, I would love to have a tool for chlorination and fluorination.

Please add more tools to the palette. For instance, I can't delete structures that I may have accidentally or intentionally placed onto the canvas. Also, it would be nice you have a feature a.) that would guess the name of the compound and b.) allow exporting the structure to other commonly used and standardized formats.
