React Native Mobile App Development Services
We build cross-platform mobile applications with React Native — from consumer-facing apps to specialized commercial device software. Our experience spans Expo managed workflows for rapid development and bare React Native CLI for deep native integration.
The Challenge
Building mobile apps that feel truly native on both iOS and Android while maintaining a single codebase is a constant balancing act. Teams face challenges with native module integration, performance optimization for real-time features, platform-specific UI behaviors, and the complexity of managing app store deployments. For specialized hardware like POS terminals, the challenge multiplies — requiring custom native bridges, hardware SDK integration, and background service management that goes far beyond standard app development.
Our Approach
We choose between Expo and React Native CLI based on project requirements. For consumer apps requiring rapid iteration, OTA updates, and broad device support, Expo provides an excellent foundation with EAS Build for production deployments. For projects requiring deep native access — custom hardware SDKs, background services, or specialized native modules — we use React Native CLI with custom native bridges. For Yanyana, our social game platform, we built a React Native Expo + CLI hybrid architecture with a pnpm workspaces monorepo containing 4 apps and 4 shared packages. The app features 12+ independent game engines with real-time WebSocket state synchronization, reconnect logic, and lobby management. A dual payment system handles Paddle for web and In-App Purchase for iOS/Android. For FoodButik POS, we wrote ~2,100 lines of custom Java Native Modules integrating the Sunmi SDK for thermal printer control, Android foreground services for uninterrupted order listening, and device-based authentication using Sunmi serial numbers. For RezMe, we used Expo SDK 53 with Expo Router v5, implementing 9 Zustand stores, multi-auth support (Email, Google, Apple, Phone OTP), deep linking, and push notifications via Expo SDK.
Technologies We Use
Key Benefits
Single codebase for iOS and Android — reduced development time and maintenance cost. Native performance with platform-specific optimizations where needed. Access to the full React ecosystem and npm package library. OTA updates with Expo for instant bug fixes without app store review. Deep native integration capability for specialized hardware and SDKs. Our React Native projects consistently ship with comprehensive testing (130+ test files, 500+ tests in the Yanyana project including Stryker mutation testing), type-safe architectures with TypeScript, and production-ready CI/CD pipelines.
