## What is cella?

See the order inside matter—not just rows of crystal data. cella is a focused 3D workspace for crystallography learners, educators, and materials researchers. Rotate selected structures, inspect atomic sites and fractional coordinates, compare three representations, and open supported CIF files on iPhone and iPad.

EXPLORE STRUCTURES
• Rotate, zoom, and pan
• Switch between ball-and-stick, space-filling, and coordination-polyhedra views
• Show the unit cell and (hkl) planes
• Build a×b×c supercells
• Tap atoms to view element names and fractional coordinates

A CURATED CRYSTAL ATLAS
Start with 20 free structures, from rock salt and diamond to fluorite, graphite, perovskites, and common metals. Pro unlocks the complete collection of 58 examples.

IMPORT AND EXPORT WITH PRO
A one-time purchase unlocks supported CIF import, the full library, and high-resolution transparent PNG export. There is no subscription.

CIF compatibility depends on file content. Unsupported or malformed files are reported in the app. Review labels and geometry before using exported images in research or publication.

PRIVATE BY DESIGN
No account, ads, tracking, or analytics. CIF files are processed on your device and never uploaded. Apple StoreKit may use an internet connection to load Pro availability, process purchases, or restore entitlements.
