The faceter's cutting companion — import designs, adapt them to your material, and cut index by index.
Culet is a mobile companion for gem faceters. It imports .ASC facet design files, adapts a design's angles to a chosen material by the guild-standard tangent-ratio method, grades each tier against the material's critical angle, plans finished size and carat yield, runs a tier-by-tier cutting session with a Live Activity, and logs finished stones against a cited materials reference. Everything stays on your iPhone — no account, no network. Angles and estimates are planning aids; proof-cut and verify against your design's instructions.
