A rounded-rect geometric sans with smooth, monoline strokes and consistently softened corners. Curves are drawn as superellipse-like arcs, giving counters and bowls a squarish-yet-rounded footprint. Terminals are clean and mostly horizontal or vertical, producing a tidy, engineered rhythm. Proportions feel compact and slightly modular, with open apertures and generous inner space that keep forms legible at display sizes.

This font works best where a modern, geometric voice is desired—UI labels, dashboards, app and software branding, and tech or gaming collateral. Its clean construction and open counters also suit short paragraphs, signage, and packaging where a crisp, contemporary texture helps maintain clarity.

The overall tone is futuristic and tech-forward, with a friendly edge created by the rounded corners and soft geometry. Its squircle construction reads modern and digital, suggesting interfaces, devices, and contemporary product branding rather than editorial tradition.

The design intention appears to be a modern sans built from rounded-rectangle geometry, balancing a digital, engineered feel with approachable softness. It aims for a recognizable silhouette through squircle curves while maintaining straightforward readability and a consistent, system-like rhythm.

Distinctive squared curves appear across both letters and numerals, reinforcing a cohesive system. The forms stay disciplined and consistent, creating a stable texture in paragraphs while still feeling characterful in headlines.
