"3D Sym Op" is an educational app focused on visualizing symmetry elements and operations in molecules of various point groups. Users can search for the 3D molecule by name, formula, 2D structure, point group, or via image recognition. The app allows selective display of symmetry elements like rotation axis, reflection plane, inversion point, and improper rotation on the scalable 3D molecule. Interactive features include touch to perform symmetry operations like rotations, pausing/resuming movement, and displaying corresponding 2D images with symmetry elements. Additionally, users can view character tables by tapping on point groups and access a quiz mode for self-assessment purposes.

Chemistry undergraduates seeking to enhance their understanding of symmetry in molecules are recommended to utilize this app. Developed as a collaborative effort between the Department of Chemistry and the School of Computing at the National University of Singapore, "3D Sym Op" aims to provide a valuable educational tool for students.
