A geometric sans built from rounded-rectangle and superellipse-like curves, with largely monolinear strokes and clean, engineered corners. Counters and bowls are squarish with softened radii, giving letters like C, G, O, and Q a compact, rounded-box silhouette. The lowercase shows a single-storey a and g, short-to-moderate ascenders, and a generally steady rhythm with slightly mechanical joins and terminals. Numerals follow the same squared-round construction, emphasizing flat horizontals and verticals with consistent curvature at turns.
Well suited to interface typography, dashboard and device labeling, and other screen-forward contexts where a clean, engineered voice is desirable. It also works effectively for tech branding, product wordmarks, and short display lines in posters or packaging that benefit from a futuristic, geometric texture.
The overall tone reads contemporary and technical—calm, controlled, and purpose-built. Its rounded-square geometry suggests digital interfaces, machinery, and sci‑fi or synth culture rather than editorial warmth. The shapes feel efficient and systematized, conveying precision and modernity.
The font appears designed to deliver a modern, system-like sans with rounded-square forms that stay friendly without losing a technical edge. Its consistent geometry and repeated superellipse construction suggest an intention to create a distinctive, contemporary display voice that remains orderly in longer settings.
The design leans on repeated motifs—flat cuts paired with generous corner rounding—creating a cohesive, modular texture in both all-caps and mixed-case settings. Circular forms are intentionally squarish, and the joints in diagonals and arms (notably in K, R, and Y) maintain a crisp, constructed feel. The sample text shows even color and stable spacing, reinforcing a structured, UI-forward personality.
