A geometric sans built from squared-round, superellipse-like forms with consistently rounded corners and even stroke weight. Curves resolve into flat-ish terminals and softly radiused joins, giving letters a compact, engineered feel rather than a purely circular construction. Bowls and counters are generally open and rectangular-oval, with smooth, controlled transitions on shapes like C, G, O, and Q. The lowercase follows the same modular logic—single-storey a and g, a compact r, and a short, centered crossbar on t—while numerals keep the same rounded-rectangle geometry for a cohesive, system-like rhythm.
It suits user interfaces, product labels, dashboards, and wayfinding where clarity and a modern, technical mood are desired. The squared-round construction also works well for contemporary branding and packaging that aims to feel sleek, digital, and organized.
The overall tone is modern and technical, suggesting interfaces, devices, and contemporary industrial design. Its rounded geometry softens the voice just enough to feel approachable, while the structured, rectilinear curves keep it precise and forward-looking.
The design appears intended to translate rounded-rectangle geometry into a practical text face: clean, consistent, and highly systematized. By emphasizing superelliptic bowls and radiused corners, it targets a contemporary, tech-adjacent aesthetic that remains functional in everyday typography.
Wide-set proportions and generous internal space help the design stay readable at smaller sizes, especially in UI-like contexts. Diagonals (V, W, X, Y) remain crisp and stable against the otherwise rounded construction, reinforcing the font’s controlled, engineered character.
