A monoline sans with a superelliptic construction: bowls and counters are built from rounded-rectangle shapes, producing squared-off curves and consistently softened corners. Strokes remain even with minimal modulation, and terminals are generally flat or gently rounded, creating a steady, engineered rhythm. Proportions feel compact and efficient, with wide, rectangular counters in letters like O/D and a distinctly squared C/G. Numerals follow the same rounded-rect geometry, with open, simple forms and a clear, utilitarian silhouette.
Well-suited to interface typography, dashboards, and product experiences where a calm, consistent rhythm supports scanning and legibility. It also fits signage and labeling that benefit from sturdy, rounded forms, and brand systems seeking a modern, tech-adjacent voice without sharpness.
The overall tone is contemporary and matter-of-fact, with a subtle friendliness coming from the softened corners. It reads as technical and system-minded rather than expressive, aiming for clarity and consistency over personality-driven detail.
The design appears intended to merge geometric efficiency with approachable softness, using superellipse-like curves to keep forms structured while avoiding harsh corners. It prioritizes uniformity and a coherent shape system that stays stable across letters and numerals in continuous text.
The design leans on repeated rounded-rectangle motifs across curves, joints, and apertures, giving text a cohesive “UI” texture. The lowercase maintains straightforward, uncluttered shapes, and the punctuation and dots appear squared/boxy to match the underlying geometry.
