A geometric sans with a superelliptic construction: bowls and counters are built from rounded-rectangle forms, giving letters a squarish footprint with softened corners. Strokes are even and unmodulated, with generous radii at joins and terminals that stay blunt rather than pointed. Curves resolve into flattened arcs, producing wide, open counters in C, G, O, and Q, while diagonals (A, V, W, X, Y) are crisp but still tempered by rounding where they meet. The lowercase follows the same rounded-rect logic, with a single-story a and g, a compact-shouldered r, and simple, straight-sided stems; figures are similarly squarish and legible, with an angular 4 and rounded, rectangular 0/8/9 forms.
This font is well suited to interface typography, dashboards, and digital product surfaces where clean geometry and consistent stroke weight help at medium sizes. Its rounded-square forms also work for signage and wayfinding, as well as modern branding and packaging that benefit from a friendly tech aesthetic.
The overall tone feels contemporary and engineered, with a soft, approachable edge from the rounded-square geometry. It reads as tech-forward and system-like, suggesting UI and product contexts, while remaining friendly enough for consumer branding and signage.
The design appears intended to merge geometric clarity with softened, superellipse shaping—delivering a distinctive square-round voice that stays highly legible. It prioritizes consistency across the character set and a contemporary, UI-ready rhythm without resorting to decorative flourishes.
Spacing appears on the open side, supporting clear word shapes in running text. The design keeps a consistent corner treatment across caps, lowercase, and numerals, which strengthens cohesion and gives the typeface a distinctive, slightly futuristic silhouette.
