ChemPencil is a powerful and easy to use App for drawing organic molecules. This fully featured App revolutionizes the way we chemists use the iPhone to support our chemistry projects.ChemPencil combines intuitive gestures with a familiar drawing tool in organic chemistry. It features a select-copy-paste sequence that integrates seemly ultrahigh resolution drawing with Keynote for iPhone. This makes ChemPencil well suited for students, researchers and professors. Draw bonds and molecules in ACS standardized style. Label heteroatoms directly in the drawing without losing sight of your document. Add common abbreviations to atoms labels. Heteroatoms labels rearrange conveniently when rotating the molecule. Represent bond stereochemistry with hashed and bold bond type. Ring building tools to draw aromatic and aliphatic rings. Add text to the document for example for naming a molecules or naming a reaction scheme. Export or email your document as a PDF. Select and copy molecules in ChemPencil and paste them directly in your Keynote or Pages document in the iPhone.
