Strong Points: Intuitive interface, molecules update automatically upon new additions
Weak Points: None
Both fun-to-use and useful (always a winning combination), the iMolecular Draw app lets users easily draw molecular structures. Rather than requiring that users place each atom individually, the app facilitates the placement of entire functional groups at a time. The best part is that the bonds update themselves automatically; that is to say, your CH4 group, for example, automatically becomes CH3 when a functional group or bond is added to it. The app is cleanly designed and uses pinch-and-zoom mechanics for easy viewing of your workspace. Users can highlight the “select” tool to manipulate individual components of the drawing, such as by rotating or moving specific atoms or functional groups. The completed drawings (along with summary information regarding total number of atoms, molecular weight, etc.) can be saved locally within the app, saved to an FTP server, or emailed.
