Cross-Platform Mobile Apps with React Native
We build high-quality iOS and Android apps with React Native, leveraging JavaScript and your existing React expertise to deliver mobile experiences that feel truly native without the overhead of maintaining two separate codebases.
Problems you shouldn't have to live with
Fragmented Development Teams
Hiring separate iOS and Android developers is expensive and creates communication gaps. Features get implemented differently, bugs are reported inconsistently, and your mobile roadmap moves at the speed of your slowest team.
Missed Market Windows
Building native apps for both platforms takes too long. By the time you launch, your competitors have already captured the users you were targeting and your product idea feels stale.
Unsustainable Mobile Costs
Maintaining two native codebases means doubling your testing, deployment, and support efforts. The total cost of ownership keeps climbing while your mobile app budget stays flat.
Wasted Web Expertise
Your team knows React and JavaScript inside out, but that knowledge goes unused when you build native mobile apps with Swift and Kotlin, forcing you to start from scratch.
How we solve it
- 1
Shared Codebase, Native Feel
React Native renders actual native UI components, not web views. Your users get platform-appropriate interactions on both iOS and Android while you benefit from a single JavaScript codebase.
- 2
Code Sharing with Web
If you already have a React web app, we can share business logic, API clients, validation, and state management between web and mobile, dramatically reducing development time and ensuring consistency.
- 3
Over-the-Air Updates
Push bug fixes and minor updates directly to users' devices without going through the app store review process. Critical patches reach your users in minutes, not days.
- 4
Native Module Integration
When you need platform-specific features like advanced camera controls, ARKit, or custom Bluetooth protocols, we write native modules in Swift or Kotlin that integrate seamlessly with your React Native app.
- 5
Performance Optimisation
We use Hermes engine, lazy loading, optimised list rendering, and the New Architecture with Fabric and TurboModules to ensure your app performs as well as a fully native application.
- 6
Automated Testing & CI/CD
Comprehensive unit, integration, and end-to-end testing with Detox, plus automated build and deployment pipelines with Fastlane and GitHub Actions so every release is reliable.

Questions we get asked
Yes. React Native powers apps for Facebook, Instagram, Shopify, Discord, and Bloomberg. With the New Architecture (Fabric and TurboModules), React Native delivers near-native performance and is well-suited for complex applications with demanding requirements.
A standard React Native app typically costs between £15,000 and £45,000. Complex apps with extensive native modules, offline support, and multiple integrations range from £45,000 to £90,000. Costs are typically 30-35% less than building separate native iOS and Android apps.
If your team has JavaScript and React experience, or you want to share code between a web app and mobile app, React Native is the stronger choice. If you prioritise pixel-perfect custom UI and have no existing JavaScript codebase, Flutter may be a better fit. We can advise based on your specific situation.
Yes. Business logic, API clients, state management, validation rules, and utility functions written in JavaScript or TypeScript can often be shared directly between your React web app and React Native mobile app, saving significant development time.
We manage the entire process for both Apple App Store and Google Play Store, including app signing, metadata creation, screenshot preparation, compliance documentation, and handling any review feedback. We also set up automated deployment pipelines for future releases.
We integrate Firebase Cloud Messaging or OneSignal for push notifications, and use background task APIs for data sync, location tracking, and scheduled operations. All notifications are configurable with user preferences and platform-appropriate delivery channels.
We use Expo for most projects because it dramatically speeds up development and simplifies app store deployments. For projects requiring custom native modules or advanced platform integrations that Expo doesn't support, we use bare React Native or eject from Expo as needed.
A standard cross-platform app takes 8 to 14 weeks. Complex applications with offline functionality, real-time features, and native module integrations take 14 to 22 weeks. React Native's fast refresh and code reuse typically reduce timelines by 30% compared to native development.
