Draw Structure
Place atoms, join them with bonds, and save your drawing as a picture.
Tap Add atom, pick an atom, then tap the canvas to place it.

Drawing a molecule is a lot like drawing a map: each atom is a place, and each bond is a road between two places. Start by picking an atom from the list — carbon is the default — then tap anywhere on the canvas to put it down. Switch to the bond tool, pick a bond type (single, double or triple), then tap one atom and then a second atom to join them. If you put an atom in the wrong place, use the Move tool to drag it, or the Erase tool to tap it away. Undo steps back one change at a time, and Clear all starts over.
Worked example — ethanol. Pick C and tap the canvas twice to place two carbon atoms side by side. Pick O and place an oxygen atom to the right of the second carbon. Switch to the bond tool, keep Single selected, and tap the first carbon, then the second carbon, then tap the second carbon and then the oxygen. You have just drawn C–C–O, the skeleton of ethanol (CH3CH2OH). The hydrogens are left out, which is normal in skeletal drawings. Download the result as a PNG to paste into your notes, or as an SVG if you want to edit it further.
