Expo Mobile Development
Expertise

Expo is a production-ready platform that extends React Native with:
• Managed workflow that handles complex native configurations
• Over-the-air updates without app store review
• Rich SDK with 50+ pre-built native modules
• Cross-platform development for iOS, Android, and web
• Faster development cycle with hot reloading
• Built-in build service and deployment tools
• No need for Xcode or Android Studio for most development

Yes, Expo provides extensive native capabilities:
• Built-in APIs: Camera, location, notifications, sensors, biometrics, and more
• Custom Native Modules: We can add any native functionality using development builds
• Expo Modules API: Create custom native modules when needed
• Bare Workflow: Full access to native code if required
• Third-party Libraries: Compatible with most React Native libraries
Our team ensures your app has access to all required native features.

Expo offers significant advantages over separate native development:
• Single Codebase: One codebase for both iOS and Android (70-90% code sharing)
• Faster Development: 40-60% faster time-to-market
• Cost Effective: Reduced development and maintenance costs
• Easier Updates: OTA updates without app store delays
• Native Performance: Compiled to native code, not webviews
• Platform Consistency: Unified experience across platforms
• Smaller Team: One team instead of separate iOS/Android teams

Expo is suitable for most mobile app categories:
• E-commerce and marketplace apps
• Social media and messaging platforms
• Enterprise and business applications
• Educational and e-learning apps
• Healthcare and fitness applications
• On-demand service apps (delivery, ride-sharing)
• Media streaming and entertainment apps
• Financial and banking applications
• IoT and smart home control apps
The only limitations are highly graphics-intensive games or apps requiring very specific native modules.

EAS Update enables instant app updates:
• Push JavaScript bundle updates without app store review
• Users get updates automatically on app launch
• Update critical bugs and features immediately
• A/B testing and gradual rollouts supported
• Rollback capability if issues arise
• Updates are limited to JavaScript/assets (not native code)
• Significantly reduces time from development to user devices

Yes, we specialize in React Native to Expo migrations:
• Assessment of current app and dependencies
• Gradual migration strategy to minimize disruption
• Native module compatibility checking
• Implementation of Expo SDK features
• Testing and quality assurance
• Setting up EAS Build and Update
• Team training on Expo workflow
Most React Native apps can be migrated to Expo with minimal changes.

Expo apps achieve native-level performance:
• React Native compiles to native code (not webviews)
• 60fps animations with Reanimated 2
• Hermes JavaScript engine for faster startup
• Image caching and optimization
• Lazy loading and code splitting
• Performance monitoring with Flipper
• Bundle size optimization techniques
Our optimization ensures your Expo app performs as well as native apps.

We implement comprehensive security measures:
• Secure storage for sensitive data
• Certificate pinning for API communications
• Biometric authentication (Face ID/Touch ID)
• Code obfuscation and minification
• Secure authentication flows (OAuth, JWT)
• API key and secret management
• Regular security audits and updates
• OWASP mobile security guidelines compliance

Our deployment process includes:
1. EAS Build configuration for iOS and Android
2. Automated testing with Jest and Detox
3. Beta testing via TestFlight and Google Play Beta
4. App store optimization (ASO) for visibility
5. Submission to App Store and Google Play
6. EAS Update setup for OTA updates
7. Monitoring and crash reporting setup
8. Post-launch support and maintenance

Our comprehensive post-launch support includes:
• Bug fixes and performance optimization
• Regular Expo SDK and dependency updates
• New feature development and iterations
• App store compliance and policy updates
• Performance monitoring and analytics
• User feedback implementation
• Security patches and updates
• 24/7 critical issue support
• Monthly performance reports and recommendations
