A geometric sans with superelliptical construction: round forms are built from rounded rectangles rather than pure circles, giving counters and bowls a squared, soft-cornered feel. Strokes are largely even with low contrast, and terminals are predominantly flat, creating a crisp, engineered silhouette. Proportions are compact with slightly condensed-looking rounds (notably in C, O, and G), while apertures stay fairly open for clarity. The lowercase follows a simplified, geometric logic (single-storey a, compact e, straightforward g), and numerals echo the same rounded-rectangle DNA with clear, modular shapes.

Performs well in UI and dashboard contexts where compact, clearly differentiated shapes are helpful, especially for labels, navigation, and buttons. The sturdy geometry also suits modern product branding, wayfinding, and short-to-medium headlines where a clean, technical voice is desired.

The overall tone feels contemporary and technical, but the rounded corners keep it approachable rather than sterile. It reads as efficient and systematic—well-suited to interfaces and product settings—while still carrying a mild friendliness from the softened geometry.

Likely designed to deliver a modern, system-like sans that balances precision with friendliness by using superelliptical rounds and consistent corner treatment. The simplified forms and uniform stroke behavior suggest an emphasis on clarity, consistency, and contemporary digital-forward aesthetics.

Round characters maintain a consistent corner radius across the set, reinforcing a cohesive “soft-square” rhythm. Angular letters like A, K, V, W, X, and Y keep sharp joins that contrast with the rounded bowls, adding energy without breaking the system. The punctuation shown (e.g., question mark) matches the squared-round style for a unified texture in running text.
