A compact sans with a condensed stance and squared, superelliptical curves that read as rounded-rectangle geometry rather than pure circles. Strokes are fairly uniform with subtly softened joins and terminals, giving counters a tidy, engineered feel. The uppercase shows simple, straight-sided construction with controlled curves (notably in C, G, O, Q), while the lowercase keeps a functional rhythm with a single-storey a and g and a closed, looped e. Numerals follow the same rounded-rect logic, with open, clean shapes and consistent spacing suited to tight settings.
This font suits user interfaces and digital product typography where space economy and clear letterforms matter, especially in navigation, labels, and compact headings. It also works well for signage and wayfinding, as well as modern packaging and poster titling where a streamlined, technical look is desired. In longer passages it can create a dense, efficient texture, making it better for short-to-medium text blocks than leisurely editorial reading.
The overall tone is modern and utilitarian, leaning toward a technical, system-like voice. Its rounded-rectangle curves soften the feel just enough to avoid harshness, but the condensed proportions keep it focused and efficient. The texture suggests clarity and practicality rather than personality-driven warmth.
The design appears intended to balance geometric cleanliness with approachable rounding, using superelliptical curves to create a cohesive, contemporary voice. Condensed proportions suggest an emphasis on information density and practical layout efficiency while maintaining consistent, well-controlled forms.
Round forms consistently favor vertical sides with rounded corners, producing a distinctive “squircle” silhouette across O-like shapes and bowls. Punctuation and dots appear crisp and straightforward, reinforcing a no-nonsense, UI-friendly impression. The condensed width creates a dense typographic color that stays orderly in multi-line text.
