Small tools that make Apple platforms easier to understand.

AtomLens

Obscure Essentials™ Mac + iPad Sync repository with iCloud Open molecule and reaction files

AtomLens is a native chemistry workspace for Mac and iPad. Open molecule and reaction files, inspect clean 2D structures and reaction schemes, save important files into a Managed Repository, optionally sync that repository through iCloud, and use Quick Look, Files, or Spotlight where each platform supports them.

QL Provider Inspector

Obscure Essentials™ Inspect UTIs Find Quick Look providers See default viewer/editor

Inspect a file or folder and see its Uniform Type Identifier (UTI), conformance tree, which Quick Look providers claim support, and which apps are registered as default viewer/editor.

CDKSwiftNativePort

CDKSwiftNativePort is a Swift-native chemistry toolkit package inspired by the Chemistry Development Kit (CDK). In simple terms, it helps developers read and write common molecule formats, generate identifiers like SMILES/InChI, create 2D depictions, and compute core molecular properties inside native Swift projects.
