A geometric sans built from rounded-rectangle (superellipse-like) curves and straight segments, giving counters and bowls a softly squared silhouette. Strokes are monoline and evenly weighted, with rounded terminals and corners that keep the texture smooth and controlled. Proportions lean horizontally open with generous interior space, while lowercase forms maintain a notably high x-height and short extenders for a compact, efficient rhythm. Numerals and capitals follow the same modular logic, with simplified, squared curves and consistent corner radii that reinforce a unified, system-like construction.
Well suited for user interfaces, dashboards, and product labeling where a clean, modern voice and clear forms are needed. It can also work effectively in logos and headline settings that benefit from a futuristic, rounded-square geometry, as well as in wayfinding or environmental text where consistent shapes support quick recognition.
The overall tone feels contemporary and tech-forward, with a streamlined, engineered personality. Its rounded-square geometry reads friendly but precise, suggesting interfaces, devices, and modern product ecosystems rather than expressive or editorial typography.
The design appears intended to merge geometric simplicity with softened corners, producing a sans that feels both technical and approachable. By relying on a consistent superellipse-like construction and monoline strokes, it aims for a coherent, contemporary system that reads cleanly in modern digital and branded contexts.
Across uppercase, lowercase, and figures, the design maintains a consistent corner radius and a restrained, schematic construction. The rounded-square ‘O/0’ shapes and the squared curves in letters like C, G, and S create a distinctive “soft-rectilinear” signature that stays legible while emphasizing a modern, modular aesthetic.
