This typeface is a geometric sans with subtly softened corners and rounded-rectangle (superellipse-like) curves. Strokes are largely monolinear with clean terminals and a steady, even texture across lines of text. Round letters such as O, C, and G lean toward squared-off ovals, while straight-sided forms (H, N, U) keep a controlled, architectural feel. Lowercase shows a single-storey a and g, compact bowls, and simple, vertical stems; counters are open and spacing reads balanced. Numerals are straightforward and legible, with a rounded 0 and a plain, sans-style 1.
Well-suited to interface typography, product labeling, and information-forward layouts where a clean, consistent texture supports scanning and readability. It also fits modern brand systems and signage that benefit from geometric structure with slightly rounded, approachable details.
The overall tone is contemporary and matter-of-fact, with a quiet friendliness coming from the rounded corners. It feels functional and system-like rather than expressive, projecting clarity, efficiency, and modern restraint.
The font appears designed to balance clarity and neutrality with a subtle geometric character. Its rounded-rectangle curves and restrained detailing suggest an intention to feel modern and reliable, working comfortably in both display snippets and continuous text without drawing attention to itself.
The design maintains consistent geometry between uppercase, lowercase, and figures, giving it a cohesive, UI-ready rhythm. Curved joins and corners are controlled rather than soft or bubbly, keeping the look crisp at text sizes while still avoiding harshness.
