Does it handle the differences between iOS and Android?

Yes, the skill includes a platform decision matrix to help you determine when to unify UI elements and when to diverge to respect platform-specific conventions like navigation and haptics.

How does this skill improve mobile app performance?

It enforces best practices like using FlatList/FlashList instead of ScrollView, implementing React.memo, and prioritizing GPU-accelerated animations to ensure smooth performance.

Can this skill help with mobile security concerns?

Absolutely. It flags security anti-patterns such as hardcoding API keys or storing sensitive tokens in unencrypted storage, recommending secure alternatives like Keychain or EncryptedSharedPreferences.

What frameworks does the mobile-design skill support?

It provides specialized guidance for React Native, Flutter, and native development using SwiftUI for iOS or Kotlin/Compose for Android.

Mobile Development

Implements mobile-first design thinking and performance-optimized patterns for iOS, Android, React Native, and Flutter applications.

This skill transforms Claude into an expert mobile architect, enforcing a touch-first philosophy that respects platform-specific conventions like iOS Human Interface Guidelines and Android Material Design. It provides mandatory checkpoints and decision matrices to prevent common AI 'mobile sins'—such as using desktop-style layouts or inefficient list rendering—ensuring that generated code is performance-optimized, battery-conscious, and offline-capable across both cross-platform and native environments.

Key Features

01Platform-Specific Guidance: Tailors UI/UX implementation for iOS (SF Pro/SwiftUI) and Android (Roboto/Material 3) conventions.

02Mobile-Centric Architecture: Provides decision trees for state management, secure storage, and robust offline synchronization strategies.

0310 GitHub stars

04Integrated Audit Tools: Includes scripts for mobile UX, touch target, and performance validation within the development workflow.

05Performance Optimization: Enforces strict rules for list virtualization, memoization, and GPU-accelerated animations to maintain 60fps.

06Touch-First UX: Applies Fitts' Law and thumb-zone ergonomics to ensure accessible and intuitive mobile interactions.

Use Cases

01Developing high-performance React Native or Flutter apps with native-feeling navigation and gestures.

02Refactoring desktop-centric codebases into mobile-first applications with proper touch targets and performance patterns.

03Conducting mobile-specific security and performance audits to identify memory leaks or insecure token storage.
