Foresight work in a number of specialised areas, from collaboration with digital agencies to developing SDKs for companies wanting to expand their markets. Read all about our varied expertise here.
React Native excels at enterprise system integration, supporting any API or protocol your business uses. Whether REST APIs, GraphQL, SOAP services, or custom protocols, React Native handles them all. The JavaScript Interface (JSI) enables direct binding to C++ libraries for high-performance integrations, including on-device ML models.
Integration capabilities include OAuth/SAML authentication for enterprise SSO, real-time data synchronisation via WebSockets, message queue integration (RabbitMQ, Kafka), database connectivity, TurboModules for custom native SDK integration, and on-device AI via TensorFlow Lite bindings. React Native's native module system ensures even the most complex integrations are possible with native performance.
For each integration we provide secure API gateway implementation using TanStack Query for caching and deduplication, data transformation and mapping, error handling and retry logic, offline queue using MMKV for resilient operation, and comprehensive integration testing. Our React Native apps seamlessly become part of your existing technology ecosystem, enhancing rather than replacing current investments.
Our React Native development quotes include everything needed for successful app launch. This encompasses: UI/UX design optimised for both platforms, complete React Native development for iOS and Android, backend API development or integration, comprehensive testing across devices, and app store submission and approval support. After launch, App Care support starts from £675 a month.
A typical split is roughly: Design and Planning (15-20%), Development and Coding (40-50%), Testing and QA (15-20%), Project Management (10-15%), and Launch and handover (5-10%). We provide detailed quotes showing exactly how your investment is allocated across project phases.
Foresight Mobile offers transparent pricing with no hidden costs. Optional services like extended maintenance, marketing materials, or additional features are clearly priced separately. We provide fixed-price quotes for defined scopes, eliminating budget uncertainty.
React Native excels at building robust offline-capable applications using various data persistence and synchronisation strategies. Libraries like Redux Persist, AsyncStorage, and Realm provide sophisticated offline storage solutions. Apps can cache data locally, queue actions for later synchronisation, and provide full functionality without internet connection.
Offline capabilities include local database storage with SQLite or Realm, intelligent sync when connection restored, conflict resolution for concurrent updates, background sync for large data sets, and offline-first architecture ensuring reliability. We've built React Native apps for field service workers, travelling sales teams, and remote locations where consistent connectivity isn't guaranteed.
We design the offline strategy around how your users actually work. Our offline-capable React Native apps include field service applications working in remote locations, retail POS systems handling transactions offline, and healthcare apps maintaining functionality in poor connectivity areas. Users experience seamless functionality regardless of connection status, with automatic synchronisation ensuring data integrity.
React Native is fundamentally different from hybrid frameworks like Ionic or Cordova. While hybrid apps run in a WebView (essentially a browser wrapper), React Native renders real native UI components, so apps look and feel native. React Native apps use platform-specific UI elements, respond to gestures natively, and access device APIs directly without WebView limitations.
The practical differences are substantial: smoother animations, native navigation transitions versus web-based transitions, platform-specific UI that users expect, direct access to newest platform features, and significantly better performance for complex applications.
For businesses, this means React Native offers the cost benefits of cross-platform development without the compromises of hybrid approaches. Your users get an authentic native experience while you maintain a single codebase.
React Native offers two update mechanisms that revolutionise app maintenance. EAS Update (the current standard; Microsoft retired CodePush's App Center hosting on 31 March 2025) allows immediate deployment of JavaScript changes and assets without app store review, with staged rollouts starting at 1% of users and automatic rollback on crash detection. Native updates through app stores are required for native code changes, major features, or iOS/Android SDK updates, typically taking 24-48 hours for review.
Maintenance advantages include a single codebase to keep up to date, automated testing via Flashlight and React Native DevTools, simplified debugging with Flipper, and proactive framework updates ensuring compatibility with latest OS versions. Expo's CNG (Continuous Native Generation) simplifies React Native version upgrades by regenerating native folders from configuration.
Foresight Mobile's maintenance packages include crash monitoring through Firebase Crashlytics or Sentry, with alerts in your Slack channel, monthly framework and dependency updates (including ongoing Android 16KB page size compliance, enforced since November 2025), performance optimisation using Flashlight benchmarks, feature enhancements based on user feedback, and updates for each new iOS and Android release.
React Native applications can achieve bank-level security when properly implemented. The framework supports all essential security features including SSL certificate pinning, biometric authentication (Face ID/Touch ID), MMKV encrypted storage (replacing insecure AsyncStorage), native Keychain/Keystore integration via react-native-keychain, code obfuscation, anti-tampering measures, and jailbreak/root detection for fintech. Coinbase rebuilt its app in React Native and has written about it on its own engineering blog.
Security best practices for React Native include storing sensitive tokens in MMKV with encryption or native Keychain, never in unencrypted storage; implementing proper authentication flows with OAuth 2.0/JWT; using certificate pinning to prevent MITM attacks; regular security audits and penetration testing; and keeping dependencies updated. Expo's SOC 2 Type 2 compliance provides enterprise security guarantees for build infrastructure.
Foresight Mobile implements comprehensive security measures in every React Native project. We conduct security audits throughout development, implement OWASP mobile security guidelines, work to GDPR, PCI DSS and FCA requirements where they apply, and provide ongoing security updates post-launch. Our React Native applications have passed stringent security assessments for financial services, healthcare, and government sectors.
Yes, React Native supports gradual migration strategies that allow you to transition from native to React Native without disrupting users. The "brownfield" approach lets you integrate React Native screens into existing native apps, enabling piece-by-piece migration while maintaining app stability. Expo now supports brownfield integration via expo-modules-core, unlocking the entire Expo ecosystem (Camera, Sensors, Haptics) for existing native apps.
Migration in 2026 follows our "Reverse Waterfall" strategy: audit dependencies for New Architecture compatibility, replace or rewrite any native modules that haven't been updated for TurboModules and Fabric, then upgrade to a current React Native release. The legacy bridge was removed in React Native 0.82, so apps can no longer run old modules through it. A critical driver for migration is the Android 16KB page size requirement: legacy React Native apps (pre-0.76) will crash on Android 15+ devices.
We plan migrations so the app keeps shipping to the stores while screens move across, and users keep their data. The App Gameplan sets out the order, the timeline and the cost before any work starts.
React Native has proven itself as an enterprise-grade framework powering applications for Fortune 500 companies worldwide. Microsoft uses React Native in its Office mobile apps, and Walmart for its shopping platform. These applications handle millions of users, complex integrations, and stringent security requirements daily.
Enterprise capabilities include robust security features (biometric authentication, encrypted storage, certificate pinning), scalable architecture patterns for high-load scenarios, mature testing frameworks, and seamless integration with enterprise systems (SAP, Salesforce, custom ERPs). React Native's modular architecture supports microservices and multi-team development approaches essential for large-scale projects.
We've built field service apps with offline synchronisation, and security-sensitive apps for financial services and healthcare clients.
Yes, React Native provides full access to all device capabilities including camera, GPS, accelerometer, biometric authentication, Bluetooth, NFC, and more. Through native modules and extensive third-party libraries, your app can utilise any feature available to native applications. Maintained libraries such as react-native-vision-camera cover most needs.
When standard libraries don't meet specific requirements, React Native's native module system allows custom integration with any platform-specific SDK or API. Foresight Mobile has implemented complex device integrations including medical device connectivity, payment terminal integration, and custom hardware communication for IoT applications.
Performance for device features matches native applications. Camera processing, real-time location tracking, and sensor data collection operate at native speeds. We've built React Native apps with advanced features like AR experiences, real-time video processing, and precise indoor positioning, proving the framework's capability to handle sophisticated device interactions.
Development of a React Native app takes 3-6 weeks for a simple app with standard features, 6-12 weeks for a medium-complexity app with custom features, backend integration and polished UI/UX, and 12-20 weeks for a complex enterprise app with multiple integrations, advanced features and rigorous testing. Those times come after the four-week App Gameplan and cover development only, so allow extra time for design, testing and app store review.
The time advantage comes from building iOS and Android together from one codebase, where native development means building each app separately. React Native's hot reloading and extensive component libraries further accelerate development, with some features taking hours instead of days to implement.
Foresight Mobile's agile methodology ensures predictable delivery through two-week sprints with clear milestones. You get a working build to try early in the project, so user feedback shapes the rest of it.
Most of our React Native builds cost £15,000 to £40,000 for a simple app or MVP. Medium-complexity apps with user authentication, payment integration and API connections cost £40,000 to £80,000, and enterprise-grade apps with complex backends, real-time features and advanced integrations start at £80,000.
The significant cost advantage of React Native becomes clear when compared to native development. Separate native iOS and Android apps cost more, because there are two codebases to build and maintain.
