This typeface is a geometric sans with a pronounced rounded-rectangle (superellipse) skeleton. Strokes are monolinear with smoothly radiused corners, producing squarish bowls and counters in letters like O, D, P, and Q rather than true circles. Terminals are largely flat and clean, while joins stay crisp, giving a controlled, engineered rhythm. Lowercase forms are straightforward and modern, with a single-storey a and g, compact apertures, and consistent corner treatment; numerals follow the same rounded-square logic, including a squarish 0 and firmly structured 2, 3, 5, and 9.
Well suited for user interfaces, product surfaces, and dashboards where a modern geometric look is desired without sharp corners. It can also work for tech-forward branding, packaging, and signage, especially where a rounded-square aesthetic aligns with a digital or industrial theme. In longer text it presents an even, controlled texture that favors clarity over personality.
The overall tone reads contemporary and interface-oriented, with a soft, approachable edge coming from the rounded corners. Its geometric discipline suggests technology, system design, and product UI, while the squircle-like shapes add a subtly futuristic flavor. The texture feels calm and orderly rather than expressive or calligraphic.
The design appears intended to translate the rounded-rectangle geometry common in digital components into a cohesive text face. By keeping strokes even and corners consistently softened, it aims for dependable legibility while projecting a contemporary, systemized character appropriate for modern screen and product contexts.
The design maintains strong visual consistency across uppercase, lowercase, and figures by repeating the same corner radius and rounded-square curves. The spacing and proportions support a stable, even line of text, and the squared counters help preserve clarity at medium and larger sizes. Diagonals in letters like V, W, X, and Y are clean and sturdy, balancing the softer curved forms.
