A monoline sans with a rounded-rectangle (superellipse) construction throughout. Curves and terminals resolve into softened corners rather than fully circular bowls, giving counters a squarish, engineered feel. Strokes are even and smooth, with generous rounding at joins; diagonals (A, K, V, W, X, Y) stay crisp while still ending in softly clipped terminals. The lowercase shows open, simplified forms (single-storey a and g) and compact, rounded bowls; the t is minimal with a short crossbar, and the i/j use round dots. Numerals follow the same rounded-rect logic, with a rectangular 0, a simple 1, and squared-off curves in 2/3/5/6/9 for a cohesive, modular rhythm.
Well suited to UI and product contexts where clarity and a modern, engineered texture are desired—such as apps, dashboards, device branding, and system-style typography. It should also work for short-to-medium text in headings, packaging, and signage where its rounded-rect forms can carry a consistent, contemporary voice.
The overall tone is contemporary and tech-forward, balancing precision with approachability. Its softened geometry reads efficient and interface-ready rather than expressive or calligraphic, making it feel futuristic without becoming cold.
Likely designed to translate superelliptic geometry into a practical sans for digital-first use, emphasizing smooth corners, consistent stroke logic, and a coherent system across letters and numerals for a unified, modern typographic identity.
Spacing appears comfortable and consistent in running text, with a steady horizontal rhythm and clear word shapes despite the geometric simplification. The distinctive squircle-like bowls and rounded terminals create a strong, recognizable texture that stays uniform across capitals, lowercase, and figures.
