A compact, geometric sans with rounded-rectangle (superelliptic) construction and soft corners throughout. Strokes are heavy and even, with minimal contrast and sturdy joins that keep counters open and stable. Curves tend toward squarish bowls (C, G, O, Q) and the diagonals (A, K, V, W, X, Y) feel firm and slightly condensed by the overall width economy. Lowercase forms are straightforward and utilitarian, with single-storey a and g, short-shouldered r, and a simple t; the numerals are similarly blocky and rounded, emphasizing clarity over ornament.
It works well for interface typography, navigation labels, dashboards, and product UI where sturdy shapes and rounded geometry maintain legibility at small to medium sizes. The strong silhouette and compact proportions also make it effective for headlines, posters, and signage that benefit from a contemporary, engineered feel.
The font reads as contemporary and purposeful, balancing a technical, UI-ready precision with a mild friendliness from its rounded corners. Its dense color and squared curves give it a confident, industrial voice that still feels approachable rather than severe.
The design appears intended to deliver a robust geometric sans optimized for modern digital contexts: squarish round forms, consistent stroke weight, and softened corners to keep the tone friendly while retaining a precise, system-like discipline.
Terminals are generally blunt with consistent rounding, producing a uniform rhythm in text. The dot on i/j is compact and square-ish, and the overall spacing supports tight, efficient word shapes suited to modern layout systems.
