A geometric sans built from rounded-rectangle and superellipse-like shapes, with smooth corners and consistent monoline strokes. Curves tend to resolve into flattened, squared bowls rather than pure circles, giving letters a compact, engineered feel. Terminals are generally rounded and the overall rhythm is even, with open apertures and simplified joins that keep forms crisp at display sizes. The figures echo the same squared-round construction, with clear, modular silhouettes and a distinctive, rectilinear softness.
It suits UI labels, dashboards, and on-device interfaces where rounded geometry feels contemporary and friendly. The sturdy, modular shapes also work well for signage, packaging, and branding systems that want a clean, technical aesthetic, and for posters or headlines that benefit from a distinctive squared-round voice.
The tone reads modern and tech-forward, like interface lettering or product labeling, while the rounded corners add approachability. Its squared-round geometry also carries a subtle retro-digital flavor reminiscent of late-20th-century industrial and sci‑fi graphics.
The font appears designed to deliver a streamlined, system-like sans that blends technical precision with softened, rounded geometry. Its superellipse-driven construction suggests an intention to feel modern and functional while remaining personable and legible in short text and display settings.
The design emphasizes uniform stroke behavior and consistent corner radii across uppercase, lowercase, and numerals, creating a cohesive system look. The sample text shows strong word-shape regularity and a controlled, slightly mechanical personality without feeling sharp or aggressive.
