This typeface is a monoline geometric sans with rounded-rectangle (superellipse) construction throughout. Curves resolve into softly squared terminals and corners, producing a consistent “rounded box” geometry in bowls, counters, and arcs. Proportions are expanded horizontally with generous internal space, while vertical strokes stay straight and even. Open apertures and simplified joins keep letterforms airy, with a distinctly drawn, engineered rhythm rather than calligraphic modulation.
It suits interface typography, wayfinding, and product or tech branding where a clean, engineered look is desirable. The wide stance and open counters make it effective for display and short-to-medium text in layouts that benefit from a modern, spacious feel.
The overall tone feels contemporary and tech-oriented, with a calm, systematic presence. Its soft-square rounding reads friendly but still precise, evoking interfaces, devices, and modern product branding more than editorial tradition.
The design appears intended to translate superelliptical, rounded-rectangle geometry into a practical sans: streamlined forms, consistent stroke weight, and open structures that emphasize clarity and a contemporary, constructed aesthetic.
Lowercase forms lean toward single-storey constructions and rounded rectangular counters, supporting a cohesive geometric voice. Numerals and capitals share the same squared-round logic, giving headlines a uniform, modular texture that holds together well in short lines and large settings.
