A rounded, monoline sans with an oblique stance and a distinctly superelliptic construction: bowls and counters feel like softened rectangles with consistent corner radii. Strokes stay even and smooth, with gently squared terminals and occasional flat horizontals that emphasize a crisp, engineered rhythm. Curves are broad and controlled rather than calligraphic, and many forms lean on vertical stems paired with rounded-rectangle bowls (notably in C/O/Q and the lowercase). Figures and capitals share the same streamlined logic, producing a cohesive, modern texture in words and lines of text.
Well-suited to interface typography, dashboards, and product or hardware branding where a modern, engineered look is desired. It can also work effectively for short paragraphs or captions when a clean, streamlined texture is appropriate, and for headings where the oblique motion adds emphasis without feeling decorative.
The overall tone is sleek and forward-looking, suggesting speed, devices, and engineered surfaces. Its rounded geometry keeps the voice approachable, while the oblique angle and squared-off curves add a technical, performance-oriented feel.
The font appears designed to merge geometric clarity with softened, superelliptic rounding, creating a contemporary sans that feels both technical and friendly. The oblique posture and squared curves suggest an intention to evoke motion and precision while maintaining a smooth, consistent texture in running text.
The design relies on repeated corner-rounding and straight-to-curve transitions, giving text a consistent “capsule” silhouette. The italic angle is steady across caps, lowercase, and numerals, and the numerals appear shaped to match the same rounded-rectangular motif for visual uniformity in UI-style readouts.
