For building iOS and Android apps with Expo and React Native
Everything you need to ship a mobile app without fighting Claude over platform-specific patterns. Expo skill handles the project structure. iOS simulator testing catches issues before you see them on device. Design skill ensures it doesn't look like a web app ported to mobile.

Official Expo skills for developing React Native mobile apps — navigation, APIs, and deployment.
Build, navigate, and test iOS apps through simulator automation — screenshots, gestures, and UI verification.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
Pressure-test spec documents with LLM reasoning before writing code — catch design flaws early.
Comprehensive best practices for React Native and Expo apps. Covers list performance, animations, navigation, UI patterns, state management, and monorepo structure.
Claude doesn't know React Native's platform-specific quirks by default. It suggests web patterns where mobile patterns are needed, mixes Expo managed workflow with bare workflow conventions, and generates components that look like a web app forced onto a small screen. The Mobile App stack fixes the model's defaults for cross-platform development.
Web developers building their first mobile app with Expo and React Native. Also useful for experienced React Native developers who want Claude to follow their team's patterns rather than guessing from the codebase.
