A rounded, monoline sans with a pronounced superellipse/rounded-rectangle construction throughout. Strokes are even and smooth, with softly squared curves and consistently rounded corners that keep counters open and shapes stable. Upright, clean forms and gently softened terminals create a neat rhythm, while the lowercase shows simple, single-storey constructions and compact join behavior (notably in m/n) that reinforces the geometric, softened structure. Numerals follow the same rounded-rectilinear logic, reading clearly with consistent stroke endings and friendly curvature.
Well-suited to interface typography, product branding, and signage where a friendly, contemporary voice is needed. The rounded structure and open counters also make it a good fit for short-to-medium text in marketing, packaging, and editorial callouts that benefit from a clean but characterful sans.
The overall tone is warm and approachable, with a contemporary, slightly playful feel driven by its rounded geometry. It reads as friendly and tech-adjacent rather than formal, balancing clarity with a distinctive soft-square character that feels inviting and modern.
The font appears designed to deliver a modern geometric sans with softened, superelliptical forms—prioritizing a cohesive rounded-rectangle aesthetic while maintaining straightforward readability for contemporary digital and brand applications.
The design leans into rounded-rectangle bowls and corners, giving letters a subtly “squircle” silhouette that stays consistent across capitals, lowercase, and figures. Spacing and proportions appear tuned for clear word shapes, with a smooth, even texture in paragraph settings.
