A crisp geometric sans built from square-rounded, superelliptic forms with smooth corners and largely uniform stroke thickness. Curves resolve into rounded-rectangle bowls rather than fully circular shapes, giving letters like O, Q, and 0 a compact, engineered feel. Terminals are clean and mostly straight-cut, counters are fairly even, and the rhythm is steady with slightly tightened apertures in letters such as e and s. The lowercase uses simple, single-storey forms (notably a and g), and the numerals follow the same squared, rounded construction for consistent texture in text and UI-like settings.
Well suited to interface typography, product labeling, wayfinding, and system-like communications where consistent geometry and clear, even color are desirable. It also works for contemporary branding and short-to-medium headlines, especially where a rounded-rect aesthetic matches the visual system.
The overall tone is modern and matter-of-fact, with a subtle tech/industrial character created by the squared curves and disciplined geometry. It feels practical and contemporary rather than expressive, reading as confident and straightforward in both headlines and interface copy.
The design appears intended to blend high legibility with a distinctive superelliptic construction—delivering a clean, contemporary sans that feels structured and scalable across both display and text contexts.
The mix of rounded corners and flat-sided curves produces a distinctive “soft square” silhouette that stays consistent across caps, lowercase, and figures. Diacritics and punctuation aren’t shown here, but the displayed core set suggests a design optimized for clarity and uniformity.
