What is CortenaUI?¶

CortenaUI is an interaction-focused UI framework for the CortenaOS ecosystem, built with Kotlin and Jetpack Compose.

CortenaUI treats motion, touch physics, and behavior as first-class citizens of the framework — not afterthoughts layered on top of visual components.

Designed around behavior¶

Most UI frameworks start with components. CortenaUI starts with interaction.

Every element is built with a clear contract for how it responds — to touch, to motion, to context. The result is an interface that feels considered at every layer: from the spring physics behind a toggle, to the way surfaces adapt across screen sizes.

Principles¶

Restraint. Visual noise is a failure mode. Every element earns its presence.

Tactility. Interfaces should feel physical. Touch feedback, motion, and physics are part of the design — not decoration.

Consistency. Interaction behavior is as much a design language as color or type. CortenaUI enforces both.

Scalability. Built for today's phones. Designed for tomorrow's form factors.
