A monoline geometric sans built from rounded-rectangle and superelliptical curves, with long horizontal spans and generous internal counters. Strokes are consistently thin with clean terminals and a lightly engineered, schematic feel. Many round letters (O/C/G/Q and their lowercase counterparts) read as softened rectangles rather than circles, while straighter letters (E/F/T/H/N) use crisp, unbracketed joins. The overall rhythm is spacious and open, with a prominent x-height and simplified, contemporary constructions that keep details to a minimum.
Best suited to display sizes where the thin strokes and wide proportions can read clearly—headlines, tech branding, product naming, interface titles, and futuristic poster work. It can also work for short UI labels and motion graphics where a lightweight, geometric look is desired.
The tone is modern and forward-looking, suggesting technology, interfaces, and concept design. Its thin, airy presence feels precise and refined rather than expressive, giving it a calm, controlled voice suited to clean, high-tech aesthetics.
The design appears intended to translate superelliptical geometry into a consistent alphabet for contemporary digital contexts, prioritizing clean structure, open spacing, and a distinctive rounded-rectangle silhouette over traditional text-face conventions.
Distinctive superelliptical bowls and rounded corners give the family a consistent ‘soft-square’ geometry. The numerals echo the same language with rounded-rectangle forms, while diagonals (notably in Z and some figures) add a slightly mechanical edge to the otherwise smooth system.
