A condensed geometric sans built from rounded-rectangle forms, with consistently softened corners and a steady monoline stroke. Curves read as superelliptical rather than fully circular, giving bowls and counters a squarish, tube-like profile. Terminals are clean and mostly blunt, with occasional subtle hooks and simplified joins that keep the texture even. The overall rhythm is tidy and measured, with compact proportions and a restrained, modular feel across both caps and lowercase.
Works well for interface labeling, dashboards, and on-screen headings where a compact, orderly voice is helpful. The condensed proportions also suit posters, packaging, and branding systems that need a technical or futuristic flavor without heavy styling. It can serve as a display or short-text face where its distinctive squared-round forms are an advantage.
The tone is clean and technical with a gentle friendliness from the rounded corners. Its squared curves and narrow stance evoke instrumentation, sci‑fi interfaces, and modernist wayfinding while staying approachable rather than severe. The result feels contemporary with a retro-futurist edge.
The design appears intended to translate rounded-rectangle geometry into a readable sans with a consistent, engineered construction. It aims for a clear, contemporary texture that feels at home in digital and industrial contexts, emphasizing modularity and softened corners over humanist detail.
Distinctive rounded-rect counters show clearly in letters like O, D, and P, while angular diagonals (V, W, X) add crisp contrast. The lowercase maintains the same geometric discipline, and the numerals follow the same softened-rectangle logic for a cohesive alphanumeric set.
