A geometric sans with rounded-rectangle construction and softened corners throughout. Strokes stay even in thickness, with a clean, engineered rhythm and wide, open apertures that keep counters clear. Curves tend to resolve into superellipse-like bowls rather than perfect circles, giving letters a squared-but-friendly silhouette. Terminals are mostly blunt or gently rounded, and joins are crisp, producing a tidy, contemporary texture in both uppercase and lowercase. Numerals match the same rounded-corner geometry, with a slashed zero and clear, simple forms.
Well-suited to user interfaces, dashboards, and digital product typography where clarity and consistency matter. The rounded-rectangle geometry also fits contemporary branding systems, packaging, and signage that aim for a sleek, tech-forward look while staying friendly and legible.
The overall tone feels modern and technical while remaining approachable due to the softened corners and generous internal space. It suggests a contemporary, product-oriented voice—precise and efficient, but not cold.
Likely designed to deliver a clean, highly legible sans built from rounded-rectangle geometry, balancing a technical feel with softened edges for everyday readability across screens and graphic applications.
Uppercase forms read especially architectural, with rounded-rectangle bowls in letters like D, O, P, and Q. The lowercase maintains clarity with single-storey shapes (notably a and g) and straightforward, utilitarian detailing, keeping the text sample highly readable at display-to-text sizes.
