A monoline sans with a squared, superelliptical construction: bowls and counters are built from rounded rectangles, and corners are consistently softened rather than fully circular. Strokes keep an even thickness with crisp terminals, giving the letters a machined, modular feel. Proportions are compact and orderly, with wide, boxy rounds in characters like O, D, and Q, and straight-sided curves in C and S. Numerals follow the same rounded-rectangle logic, producing sturdy, sign-like figures with clear, simplified shapes.

Well-suited to interface typography, dashboards, and product displays where a clean, engineered aesthetic is desired. It also works effectively for headlines, posters, and branding in technology, hardware, gaming, and transportation contexts, and holds up in short blocks of text where its compact, squared rhythm becomes a distinctive texture.

The overall tone is contemporary and tech-forward, with a controlled, engineered rhythm that feels utilitarian and modern. Its rounded-square geometry reads as futuristic without becoming playful, projecting clarity, precision, and a slightly industrial coolness.

The design appears intended to translate rounded-rectangle geometry into a practical, readable sans for contemporary applications. By keeping stroke weight even and corners systematically softened, it aims for a modern, digital-friendly voice that remains structured and consistent across letters and numerals.

Several forms emphasize squareness and closure: C, S, and G show tight, rectangular curves; the Q uses a small internal tail detail; and the lowercase set keeps simple, largely single-storey constructions that reinforce the font’s modular system. The consistent corner radius across letters and digits creates a cohesive, system-font-like texture in text.
