AtomLens

AtomLens is a native iPad chemistry app for opening, viewing, translating, browsing, saving, extracting, and sharing molecule and reaction files.

Work entirely on-device with common chemistry formats including Molfile, SDF, SMILES, CXSMILES, Reaction SMILES, RInChI, InChI, MOL2, PDB, XYZ, CML, RXN, and RDF.

Use the live depiction canvas to zoom, pan, rotate, restyle, and inspect structures or reactions. The iPad workspace includes an input sidebar for pasted chemistry text, an experimental on-device IUPAC-name entry action, and a native customizable toolbar with grouped visualization controls for carbons, element colors, map colors and numbers, bond coloring, aromatic circles, and highlight style. Save important structures into the built-in Structures Repository, browse them later with depiction cards and chemistry metadata, and reopen repository files directly from Files. Save writes AtomLens-readable chemistry documents into the managed repository, while Share hands off depiction exports such as SVG, PNG, and PDF through the system share sheet.

AtomLens also supports chemistry-aware extraction workflows for splitting multi-structure SDF files and multi-reaction SMILES files. When you need to hand off results, share the current depiction as SVG, PNG, or PDF.

The iPad app includes a default-on Sync chemical files over iCloud preference. When iCloud Documents is available, AtomLens can keep managed repository files together with their tags, favorites, and recent-use metadata across your AtomLens devices. If you prefer not to sync on a given iPad, repository-backed Save, Extract, Browse, Files, Quick Look, and repository search features stay disabled on that device until you turn sync back on.

• Adjust visualization styles from a native grouped toolbar control

• Save structures into the built-in Structures Repository

• Browse saved repository items with depiction previews, metadata, and tag filters

• Use the AtomLens File Provider to access repository files from Files

• Preview supported repository files with Quick Look on iPad

• Optionally sync managed repository files plus their tags, favorites, and recent-use metadata over iCloud

• Share the current depiction as SVG, PNG, or PDF

• Run extraction workflows directly on-device
