Molecule Lab is a simple yet powerful editor allowing users to build and visualize molecules in 3D. Our molecule editor can build more molecules than before, as it now supports three new elements—oxygen, nitrogen, and chlorine—in addition to carbon and hydrogen, double bonds, triple bonds, branches, and different rotation conformations. These incredible new features are enhanced by the flexibility of our molecule editor, which we further upgraded with undo, redo, and delete controls. Molecules can be saved and edited in the future. Additionally, we introduced the capability to share molecules via text message, email, and other third-party services for notetaking and document sharing. This seamless integration with different apps makes Molecule Lab more powerful for sharing and referencing molecules in the future. With all these exciting features, we are thrilled to debut a new look and feel for Molecule Lab. We hope the beautiful modern design will enrich each user’s experience with Molecule Lab.
