A geometric sans with monoline construction and a distinctive superelliptic skeleton: curves resolve into rounded-rectangle forms with consistently softened corners. Counters are fairly open and rectangular-oval, and terminals are cleanly cut with minimal modulation. The caps are sturdy and compact with broad shoulders, while the lowercase keeps a straightforward, engineered rhythm; the single-storey a and g, short-armed r, and flat-topped t reinforce a utilitarian, UI-ready feel. Numerals follow the same rounded-rectangle logic, with a notably square-ish 0 and evenly weighted figures.
Well suited to interface typography, product branding, and information design where a modern, structured voice is needed. Its clean geometry and open counters support legibility for navigation, controls, and short blocks of text, while the distinctive rounded-rectangle forms add recognizable character for titles, signage, and data-rich layouts.
The overall tone is contemporary and pragmatic, balancing a slightly soft, approachable edge from the rounded corners with a precise, technical sensibility. It reads as calm and efficient rather than expressive, lending a subtly futuristic, product-oriented character.
The font appears designed to combine the neutrality of a contemporary sans with a signature superelliptic geometry, creating a system-friendly typeface that feels modern and precise without becoming harsh.
The design’s identity comes from the consistent “squircle” curvature—round where expected, but never fully circular—which produces a tight, orderly texture in words. The boldness of key junctions and the simplified diagonals help maintain clarity at medium and large sizes, especially in headings and labels.
