A crisp sans with a geometric backbone and rounded-rectangle (superelliptic) construction in the bowls and counters. Strokes are even and consistent, with softly rounded outer corners and smooth transitions that keep forms friendly without becoming bubbly. Proportions are balanced and straightforward, with open apertures and clear spacing that maintains legibility in both uppercase and lowercase. Figures follow the same rounded-square logic, giving the set a cohesive, system-like rhythm.
Well-suited to digital UI and product surfaces where clear letterforms and a controlled, geometric rhythm help readability at a range of sizes. It can also work for wayfinding and modern editorial headlines when a clean, slightly softened technical look is desired.
The overall tone is contemporary and restrained, combining a technical neatness with a mild warmth from the softened corners. It feels efficient and organized rather than expressive, suited to interfaces and modern brand systems where clarity and consistency matter.
The design appears intended to deliver a contemporary geometric sans that feels systematic and precise, while softening the clinical edge through rounded-rectangle shaping. Its consistent construction suggests a focus on clarity, cohesion across alphanumerics, and an interface-friendly personality.
Rounded corners are applied consistently across straight joins and curved strokes, producing a unified “squircle” feel in letters like O/C/D as well as in numerals. The design avoids sharp spurs or pronounced calligraphic modulation, keeping emphasis on even color and predictable geometry.
