A geometric sans with a rounded-rectangle (superellipse) skeleton: curves are broad and squarish, corners are softened, and strokes stay even with subtle optical modulation. Proportions are expansive, with generous internal space in letters like O, D, and P, and a calm, steady rhythm across lines. Terminals are predominantly flat, and joins feel engineered rather than calligraphic, giving the design a crisp, contemporary finish. The lowercase shows simple, single-storey forms (notably a and g) with compact bowls and clear counters, maintaining a consistent, modular feel from letters to numerals.
Works well for interface typography, wayfinding, and product-led branding where a clean, contemporary sans is needed with a softer geometric personality. The wide proportions and open counters help in large sizes for headlines and display text, while the steady stroke behavior supports short-to-medium reading in dashboards, captions, and labels.
The tone reads modern and approachable—clean enough for functional UI work, but softened by rounded corners that keep it from feeling harsh. Its geometry suggests a tech-forward, product-oriented voice, while the wide stance and open shapes make it feel friendly and confident.
The design appears intended to blend geometric precision with softened edges, creating a sans that feels engineered yet approachable. Its consistent superelliptical curves and straightforward construction point to a focus on clarity, modernity, and a distinctive rounded-rect aesthetic suitable for digital-first contexts.
The numerals follow the same squarish-rounded logic, with clear silhouettes and ample counters (especially 0, 8, and 9). Overall spacing and shapes favor clarity and stability, with distinctive, boxy-round curves that give the face a recognizable texture in headlines and short text.
