What problem does it solve? Building Expo apps that feel truly native requires knowing which components, colors, and libraries match Apple HIG and Android Material conventions. This Skill provides concrete guidance on styling, controls, icons, media, storage, and visual effects so screens look and behave like platform-native UI instead of generic cross-platform layouts. ## Core Features & Use Cases - Native Styling System: Use the Color API from expo-router for semantic iOS/Android colors that auto-adapt to light and dark mode, plus CSS boxShadow, continuous border curves, and safe-area-aware scrolling. - Native Controls & Icons: Implement Switch, Slider, SegmentedControl, DateTimePicker, and SF Symbols via expo-symbols with weights, scales, and animations. - Media, Storage & Effects: Camera and audio/video with expo-audio/expo-video, localStorage/SQLite/SecureStore persistence, blur and liquid glass effects, CSS gradients, and WebGPU/Three.js 3D scenes. - Use Case: When building a settings screen or camera flow in an Expo app, use this Skill to pick the right native control, apply semantic colors, add haptics, and decide whether Expo Go suffices or a custom build is required. ## Quick Start Use the expo-native-ui skill to build a native-feeling settings screen with semantic colors, a segmented control, and SF Symbol icons.
