A geometric sans with a superellipse construction: strokes are monoline and terminals resolve into generously rounded corners, producing squared-off bowls and counters. Curves are mostly built from rounded-rectangle segments rather than circular arcs, giving letters like O, C, and G a compact, engineered feel. The face maintains even stroke rhythm with open apertures and tidy internal spacing; diagonals (V, W, X, Y) are straightforward and slightly softened at joins. Figures follow the same rounded-rect logic, with a squared 0 and simple, legible 1–9 forms.

Well-suited to interface typography, dashboards, and product surfaces where a clean, engineered geometry helps maintain clarity. It also fits contemporary tech branding and short to medium-length headlines, and can work in signage or packaging where rounded-square forms convey modernity without harshness.

The overall tone reads modern and technical while staying approachable due to the softened corners and consistent, calm rhythm. It suggests a contemporary UI or product aesthetic—precise and controlled rather than expressive or calligraphic.

Likely designed to translate superellipse/rounded-rectangle geometry into a practical text-and-display sans that feels contemporary and system-ready. The consistent monoline stroke and softened corners emphasize neutrality, legibility, and a cohesive futuristic aesthetic.

In the sample text, the uniform stroke and rounded-square geometry stay coherent across long lines, and punctuation (such as the colon and apostrophe) matches the blunt, squared-dot language. The uppercase is compact and sturdy, while the lowercase keeps a straightforward, functional structure with minimal modulation.
