A geometric sans with a superellipse construction: straight-sided stems and bowls resolve into generously rounded corners, giving many letters a rounded-rectangle feel. Strokes are largely monolinear with consistent terminals, and curves are smooth and tightly controlled rather than calligraphic. Proportions are compact with short extenders and a steady rhythm; counters stay fairly open despite the squared-off curvature. Distinctive details include a single-storey “a”, a looped “g” with a descender, and wide, arched forms in letters like “m” and “w” that emphasize the rounded-rect geometry. Numerals follow the same soft-squared logic, keeping a coherent texture across text and UI-like strings.
Well-suited for user interfaces, dashboards, packaging labels, and product branding where a modern geometric voice is needed. Its clean, rounded-rect forms also work well for short headlines, navigation, and signage-style applications where clarity and a distinctive silhouette matter.
The overall tone is contemporary and engineered—clean and systematic—while the rounded corners keep it approachable rather than stark. It reads as tech-forward and utilitarian, with a subtle retro-futurist signage flavor in the softened rectangular curves.
The font appears designed to translate a rounded-rectangle grid into a readable sans, balancing a functional, digital feel with softened corners for approachability. Its consistent geometry suggests an intention to provide a cohesive system for contemporary display and UI typography with a recognizable superellipse signature.
The design leans on vertical and horizontal stress with minimal modulation, producing an even gray in paragraphs. Several glyphs show intentionally unconventional geometry (notably in rounded multi-arches and squared bowls), which adds character while staying within a consistent system.
