How does React Native compare to Flutter?

React Native renders native platform components and is the better choice for teams with JavaScript/React expertise or existing web codebases to share logic with. Flutter renders every pixel via its own Skia/Impeller engine, giving pixel-perfect cross-platform UI — better when design consistency across platforms is more important than native feel.

Should I use Expo or bare React Native?

Expo Managed Workflow for most new projects — it eliminates native build complexity, provides EAS Build CI/CD, and covers the majority of device API needs. Bare workflow when you need custom native modules not supported by Expo, or when migrating an existing bare project.

Can React Native achieve 60fps scroll and animation performance?

Yes — with the New Architecture, Reanimated 3 (runs on the UI thread), and FlashList (virtualised, high-performance list rendering). Poor React Native performance is almost always a code issue, not a framework limitation.

How do you handle platform-specific UI differences?

React Native's Platform API and file extension conventions (.ios.tsx, .android.tsx) let you branch platform-specific code cleanly. We follow a strategy of shared logic with platform-specific presentation only where the UX genuinely differs.

How are React Native apps submitted to the App Store and Play Store?

EAS Submit automates store submission from CI. We manage certificates, provisioning profiles, and keystore files, and handle the full submission and review process. First release takes slightly longer for Apple review (1–7 days); subsequent updates are usually approved in 24 hours.

What We Build

Our React Native Development Services

Custom React Native App Development

End-to-end iOS and Android applications built with React Native New Architecture, Expo, and TypeScript — designed and submitted to both stores.

React Native + Web Code Sharing

Monorepo architectures that share business logic, hooks, and API clients between React Native and React web — reducing total development cost by 30–50%.

Expo Application Development

Managed and bare Expo workflow applications with EAS Build and EAS Submit for streamlined CI/CD and over-the-air (OTA) updates.

React Native Performance Optimisation

Profiling and optimisation of React Native apps — Hermes engine, FlashList, New Architecture migration, and JS bundle size reduction.

Native Module Development

Custom native modules and Turbo Modules in Swift/Kotlin for device features not covered by the existing ecosystem.

React Native App Modernisation

Upgrade legacy React Native apps: class components to hooks, Old Architecture to New Architecture, and navigation stack upgrades.

Technology Advantage

Why React Native for Your Business?

React Native is the most popular framework for cross-platform mobile development — and for good reason. It renders native platform components (not a WebView), shares business logic and hooks with your React web app, and gives access to device APIs through a rich third-party ecosystem. At Bluejay, we use the New Architecture (Fabric + TurboModules) on all new React Native projects for dramatically improved performance and bridgeless communication.

True Native Components

React Native renders actual platform UI components — UIView on iOS, View on Android — not a WebView. The result feels and performs like a native app to users.

Shared Logic with Web

Hooks, context, stores, API clients, and utility functions can be shared 1:1 with your React web app in a monorepo, reducing total engineering effort significantly.

Over-the-Air Updates

Expo EAS Update (and Expo Go) let you push JavaScript updates to users instantly — bypassing app store review for non-binary changes.

New Architecture Performance

The Fabric renderer and TurboModules eliminate the async bridge bottleneck, enabling synchronous native API calls and 60fps concurrent UI rendering.

Single Team, Two Platforms

One team maintains both iOS and Android — no context-switching between Swift and Kotlin, no duplicated features, no diverging codebases.

Rich Third-Party Ecosystem

React Native has battle-tested libraries for navigation (React Navigation), payments (Stripe SDK), maps (Mapbox), analytics, and virtually every mobile use case.

How We Work

Our Processes

We deliver a structured process for seamless project execution. From understanding your requirements to delivering the final solution, we ensure proactive technology services based on your business needs.

Sprint Planning

We break the project into focused sprints with clearly defined goals, priorities, and deliverables, keeping the team aligned and progress visible at all times.

Design & Development

Each sprint delivers working software from UI design to backend logic, with continuous collaboration and daily standups to keep momentum high.

QA & Testing

Every sprint output goes through rigorous quality assurance, automated testing, and code review to ensure reliability, performance, and security.

Review & Iteration

At the end of each sprint, we demo progress to stakeholders, collect feedback, and refine the roadmap to ensure the final product perfectly fits your needs.

Release & Optimization

Once validated, we deploy to production and monitor closely. Post-launch optimizations ensure your product performs at its best from the first day live.
