Calligraphy Angle Lab

About

Calligraphy Angle Lab is a paid, local-first practice geometry desk for broad-edge calligraphers. Configure hand style, nib width, pen angle, x-height, ascender, descender, slant, and line gap. The ruled specimen visualizes the resulting system. Log repeated strokes with measured angle, width, height, spacing, and notes; Rhythm calculates mean angle and spreads. Audit checks sample coverage, proportions, angle control, spacing, and line clearance. Save multiple sheets, duplicate revisions, and export JSON or CSV. No login, subscription, IAP, ads, analytics, tracking, camera, cloud sync, AI, or backend.
