What this skill does
Mobile Development Skill Production-ready mobile development with modern frameworks, best practices, and mobile-first thinking patterns. When to Use Building mobile applications (iOS, Android, or cross-platform) Implementing mobile-first design and UX patterns Optimizing for mobile constraints (battery, memory, network, small screens) Making native vs cross-platform technology decisions Implementing offline-first architecture and data sync Following platform-specific guidelines (iOS HIG, Material Design) Optimizing mobile app performance and user experience Implementing mobile security and authentication Testing mobile applications (unit, integration, E2E) Deploying to App Store and Google Play Technology Selection Guide Cross-Platform Frameworks: React Native: JavaScript expertise, web code sharing, mature ecosystem (121K stars, 67% familiarity) Flutter: Performance-critical apps, complex animations, fastest-growing (170K stars, 46% adoption) Native Development: iOS (Swift/SwiftUI): Maximum iOS performance, latest features, Apple ecosystem integration Android (Kotlin/Jetpack Compose): Maximum Android performance, Material Design 3, platform optimization See: references/mobile-frameworks.md for detailed framework comparisons Mobile Development Mindset The 10 Commandments of Mobile Development: 1. Performance is Foundation, Not Feature - 70% abandon apps >3s load time 2. Every Kilobyte, Every Millisecond Matters - Mobile constraints are real 3. Offline-First by Default - Network is unreliable, design for it 4. User Context > Developer Environment - Think real-world usage scenarios 5. Platform Awareness Without Platform Lock-In - Respect platform conventions 6. Iterate, Don't Perfect - Ship, measure, improve cycle is survival 7. Security and Accessibility by Design - Not afterthoughts 8. Test on Real Devices - Simulators lie about performance 9. Architecture Scales with Complexity - Don't over-engineer simple apps 10. …
