MolPad is a chemical structure drawing app specifically designed for tablets. It allows you to draw chemical structures freehand with a finger, stylus or mouse, just as you would with pencil and paper. The raw ink is converted on the fly to an underlying connection table. Both chemical bonds and handwritten atomic symbols are recognised, cleaned and incorporated into the structure.
