A geometric sans with a rounded-rectangle (superellipse) construction throughout. Strokes are monoline with smooth joins and consistently softened corners, giving counters a squarish-but-rounded feel. Curves are controlled and slightly boxy rather than perfectly circular, and terminals are clean and uniform. Uppercase forms are broad and stable, while lowercase keeps simple, highly legible shapes with open apertures and clear differentiation between similar forms. Numerals follow the same squared-round geometry, with even stroke weight and straightforward, utilitarian shapes.
Well-suited to user interfaces, dashboards, and app/web typography where clarity and a modern feel are important. Its rounded-rect geometry also works effectively for tech-forward branding, product wordmarks, and packaging, as well as signage and headlines that need a clean, contemporary voice.
The overall tone feels contemporary and slightly futuristic, balancing a technical, engineered precision with approachable softness from the rounded corners. It reads as calm and efficient rather than expressive, with a subtle “interface” personality that stays friendly.
The design appears intended to deliver a modern geometric sans that feels engineered and consistent, while using rounded-square forms to create a distinctive identity and a softer, more approachable texture than a strictly circular geometric sans.
Spacing appears generous and consistent, helping the type hold up at display sizes while remaining readable in longer lines. The superelliptical curves give distinctive identity without becoming decorative, and the letterforms maintain a steady rhythm across mixed-case text and figures.
