This typeface is a geometric sans built from rounded-rectangle (superellipse-like) forms, producing corners that are softly radiused rather than fully circular. Strokes are largely monolinear with crisp, flat terminals and a consistent, engineered rhythm. Curves tend toward squared rounds, and many letters show subtly narrowed joins and compact counters, giving the design a tidy, controlled texture. The lowercase is notably tall with simple, upright construction and minimal modulation, while the numerals follow the same squared-round logic for a cohesive set.
It suits UI and product typography where crisp construction and clear shapes are needed, and it scales well to headings where the superelliptic silhouettes become part of the identity. It can also work for signage and wayfinding, as the open, geometric forms remain legible and consistent across sizes.
The overall tone feels contemporary and systematic—more technical than friendly—suggesting precision, interface clarity, and an architectural sense of order. Its rounded corners soften the geometry just enough to keep it approachable without losing a distinctly modern, utilitarian voice.
The font appears designed to deliver a modern, engineered sans with a distinctive superelliptic skeleton—balancing strict geometry with softened corners for a polished, contemporary feel in digital and brand contexts.
Round characters (like O/C/G and their lowercase counterparts) read as rounded rectangles, creating a distinctive silhouette in headlines. The design favors straightforward, functional shapes over calligraphic detail, helping it maintain a stable, evenly paced color in text while still looking characteristic at larger sizes.
