Crys-CAST

Open crystal structure files, switch display modes, preview PXRD, and check pore volume with faster Pore Analysis and 3D pore-space display on iPhone and iPad.

Crys-CAST is a local structure viewer for crystallography and molecular modeling workflows.

Open CIF, XYZ, PDB, MOL, SDF, MOL2, and RES files from Files or other apps. Inspect atoms, bonds, unit cells, display styles, display scope, atom labels, scale bars, coordination polyhedra, thermal ellipsoid display when valid anisotropic displacement data is available, and Spacefill views on iPhone or iPad.

For periodic structures, Crys-CAST includes quick mobile analyses: simulated PXRD pattern, crystal plane list, BFDH morphology preview, Structure Check summaries, and Pore Analysis for geometric pore volume and porosity. Pore Analysis uses a fixed built-in vdW radii table, a finite probe, and a periodic grid; the result can be shown as a 3D pore-space surface in the viewer.

Build and organize a local structure library. Structure files stay on device, and archive import/export tools help move collections between devices. Use fullscreen viewer, saved view state, figure export, and presentation-friendly layouts for teaching, meetings, and quick research discussion.

Crys-CAST is designed for inspection and teaching-scale analysis, not publication-grade crystallographic refinement. Always verify important conclusions with source data and specialist workflows.
