Sketch UI design & app screens

Sketch is a vector design tool for creating interfaces, icons, and design systems, historically Mac-native and a longtime staple of UI designers. It now offers web-based collaboration alongside its desktop app.

The interface is the canonical canvas-plus-inspector design layout, with layers, symbols, and a precise properties panel. Designers will recognize its foundational patterns for artboards, component libraries, and vector editing, making it a valuable reference for anyone building creative tools or studying the lineage of modern design software.
