ImagoChem is a chemistry teaching and lesson preparation app for secondary school teachers, with separate versions for Mac and iPad. It presents chemical structures, reactions, and laboratory apparatus as interactive visualizations that users can rotate, zoom, or play as animations. Topics include ball and space filling molecular models, crystal cells, electron configurations and orbitals, ionic reactions, electrochemical cells, and organic reaction sequences showing bonds forming and breaking. The app also includes three dimensional models of common glassware and assembled laboratory equipment, with adjustable views. Teachers can organize lessons by textbook topics, prepare slides and still images, and return to prepared material during class. On Mac, the app is intended for lesson preparation and requires macOS 12 or later. On iPad, teachers can manipulate models, play animations, project the display, and annotate it with Apple Pencil; the iPad version requires iPadOS 15 or later. Core functions run locally without an internet connection. Preferences, lesson materials, snapshots, and annotations are stored on the device, and the app states that it does not collect data or include advertising, statistics, or analytics SDKs. ImagoChem is sold through the Apple App Store as a one time purchase, with Mac and iPad versions purchased separately.
