Custom React Native Development for Scalable Mobile Applications
The Runner Software Solutions builds custom React Native applications for Android and iOS from a single, shared codebase — combining React's component architecture with JavaScript and TypeScript to deliver cross-platform apps without maintaining two separate native builds. Our React Native engineering covers UI development, native module integration where platform-specific functionality is required, backend and API architecture, third-party integrations, security, and performance optimization.
We work with startups building an MVP that needs to reach both app stores quickly, and with enterprises running React Native applications that need modernization, native module development, or deeper integration with ERP and CRM systems. Every build accounts for the realities of shipping a production app: dependency management, OS compatibility as Android and iOS evolve, and the testing discipline cross-platform apps require.
What Is React Native Development?
React Native development is the process of building mobile applications using React Native — a framework that lets developers write application logic and UI in JavaScript or TypeScript, using React's component model, while rendering to genuine native UI components on Android and iOS rather than a web view. The result is a single, largely shared codebase that runs on both platforms, with the ability to drop into native Kotlin/Java or Swift/Objective-C code when a feature requires direct platform access.
Key concepts that define React Native development:
- React provides the component-based architecture, state management patterns, and declarative UI paradigm that React Native is built on
- JavaScript/TypeScript is the language application logic is written in, with TypeScript adding static typing for larger, longer-lived codebases
- Android and iOS are the two platforms a single React Native codebase can target simultaneously
- Native modules allow React Native code to call directly into native Android or iOS code when a feature needs capabilities the framework doesn't expose by default
- Native APIs — device hardware and OS-level services (camera, GPS, biometrics, notifications) — are accessible through React Native's core libraries or custom native modules
- Components are the reusable building blocks of the UI, written once and shared across both platforms in most cases
- Shared code — the majority of business logic, state management, and UI in a typical React Native app is written once and runs on both platforms
- Backend/API systems — most React Native applications depend on backend services for data, authentication, and business logic, communicating over REST or GraphQL APIs
Businesses consider React Native when they need to reach both Android and iOS users without maintaining two fully separate native codebases, when their team has existing JavaScript or React expertise, or when the product's iteration speed benefits from a shared codebase. React Native isn't automatically the right choice for every mobile project — see the dedicated comparison sections below on when native development or Flutter might be a better fit.
React Native Development Services
Custom React Native App Development
We design React Native applications around your specific business requirements and user workflows, rather than adapting a generic template — including custom UI, business logic, and integration architecture built for your actual product.
Cross-Platform React Native Development
React Native's core value is a shared codebase: business logic, most UI components, and state management written once and running on both Android and iOS, with platform-specific implementation applied selectively where a feature genuinely needs to behave differently per platform.
React Native UI/UX Development
We design user flows, wireframes, and prototypes before development, building toward a reusable component library and design system — with responsive layouts, animations, and accessibility considered from the start, and platform-specific UI conventions respected where they matter to the user experience.
React Native MVP Development
For early-stage products, we scope a minimum feature set that validates your core assumptions, instrument the app with analytics from day one, and build the architecture to support iterative development as user feedback comes in.
Enterprise React Native Development
Enterprise React Native applications — employee tools, field-service apps, partner applications — need secure authentication, role-based access, ERP/CRM integration, and reporting. Cross-platform development is particularly valuable at the enterprise level, where reaching both Android and iOS users with a single engineering team reduces long-term maintenance overhead.
For enterprise mobile projects that are part of a broader platform initiative, our software product development team can support the wider technology roadmap alongside the mobile application.
React Native Ecommerce Development
We build mobile commerce experiences in React Native — product catalogs, search and filtering, cart and checkout, payment integration, order tracking, customer profiles, and push notifications for order updates and promotions.
React Native Backend Development
Most React Native applications depend on backend infrastructure — APIs, authentication, databases, business logic, and cloud infrastructure — built specifically to support mobile client requirements like efficient payloads and reliable offline/online transitions.
React Native API Integration
We build and integrate REST APIs, and GraphQL where appropriate, connecting React Native apps to backend services and third-party platforms, with proper authentication, data synchronization, and webhook handling.
React Native App Migration
We support migration to React Native from native Android or iOS codebases, from older React Native versions, or from legacy hybrid frameworks — always beginning with a technical audit of the existing application before proposing a migration strategy.
React Native App Modernization
For applications built on outdated React Native versions or accumulated technical debt, we address outdated dependencies, architecture issues, performance problems, and security gaps without necessarily requiring a full rebuild.
React Native App Maintenance
Post-launch, React Native apps need ongoing dependency updates, React Native version upgrades, OS compatibility maintenance, bug fixes, security patching, and performance monitoring as Android and iOS continue to evolve.
React Native + React Ecosystem
React Native is built on React, but writing React Native code isn't the same as writing React for the web — it's important to understand both the connection and the difference.
What carries over from React:
- Components — the same mental model of building UI from composable, reusable components
- Props and state — the same patterns for passing data down and managing component-local state
- Hooks — useState, useEffect, useContext, and custom hooks work the same way conceptually in React Native as in React for web
- Reusable logic — business logic, custom hooks, and state management patterns are often directly transferable in concept
- Component architecture — the same principles of composition, lifting state up, and separating presentational from container components apply
What's genuinely different:
React Native doesn't render HTML — there's no div or span; instead, React Native provides its own primitive components (View, Text, Image, ScrollView, etc.) that map to native platform UI elements. Styling uses a JavaScript-based system similar to CSS but not identical to it, with no direct CSS file support. Navigation, gestures, and platform APIs work differently than in a browser environment. React web code cannot simply be copied into a React Native project — the component tree, styling approach, and available APIs are fundamentally different, even though the underlying React concepts transfer directly.
For teams with existing React web expertise, this means a real head start on the conceptual model and development patterns, but genuine ramp-up time is still required to learn React Native's specific component library, styling system, and native integration points.
JavaScript & TypeScript for React Native
React Native applications are written in JavaScript or TypeScript. While JavaScript works perfectly well for smaller projects, TypeScript adds meaningful value as application size and team size grow:
- Type safety — catching a whole class of bugs at compile time rather than at runtime in production
- Interfaces — clearly defining the shape of data flowing through the app, particularly valuable for API response handling
- Generics, used where appropriate, allow reusable components and functions to work safely across multiple data types
- Asynchronous programming — Promises and async/await are core to how React Native apps handle API calls, and TypeScript's type checking extends cleanly to async code
- Maintainability — type definitions serve as living documentation for developers joining the project later
- Developer productivity — IDE autocomplete and inline error detection reduce debugging time
- Code quality — enforced typing tends to surface design issues earlier in development
We generally recommend TypeScript for any React Native application beyond a small prototype, given how much it reduces a specific, common category of runtime errors — but the decision depends on team familiarity and project scope, which we assess during discovery.
React Native Architecture
A React Native application is built from several distinct layers:
- Presentation layer — the components and screens users interact with directly
- Components — reusable UI building blocks, ideally organized into a coherent, shared component library
- Navigation — managing screen transitions and the app's overall information architecture
- State management — handling application data and how it flows through the component tree
- Business logic — the rules governing how the app actually behaves, ideally separated from UI code for testability
- Service layer — a clear abstraction between UI code and external calls (APIs, storage, device features)
- API layer — how the app communicates with backend services
- Data layer — how data is structured, cached, and kept consistent across the app
- Local storage — persisting data on-device for offline access or performance
- Backend — the server-side systems the app depends on for data and business logic
- Authentication — verifying user identity and managing session state
- Caching — reducing redundant network requests and improving perceived performance
State and data management approaches we select from based on project complexity:
- Redux Toolkit — well suited to larger applications with complex, shared state and a need for predictable, centralized state management
- Context API — appropriate for simpler state-sharing needs where a full state management library would be unnecessary overhead
- Zustand — a lighter-weight alternative to Redux for applications that need shared state management without Redux's boilerplate
- React Query / TanStack Query — purpose-built for server state (API data, caching, refetching, synchronization), often used alongside a separate solution for local UI state
We don't default to the most feature-rich library for every project. A small app with limited shared state doesn't need Redux Toolkit's overhead; a data-heavy app with frequent API interaction genuinely benefits from TanStack Query's caching and synchronization capabilities regardless of app size.
React Native New Architecture
React Native's modern architecture represents a significant shift in how the JavaScript and native layers of an app communicate, with real implications for performance and native integration:
- Fabric — React Native's new rendering system, changing how the UI layer communicates with native platform views to reduce overhead in rendering and updates
- TurboModules — the modernized native module system, enabling native modules to be loaded lazily rather than all at app startup, with more direct, type-safe communication between JavaScript and native code
- JSI (JavaScript Interface) — allows JavaScript to hold direct references to native objects and call native methods synchronously, replacing the older asynchronous bridge
- Bridgeless architecture, where relevant, removes the traditional React Native bridge entirely, with JSI handling communication directly
What this means practically: the new architecture reduces communication overhead between JavaScript and native code, which matters most for apps with frequent, high-volume interaction between the two layers — heavy list rendering, animations, or apps making extensive use of custom native modules. We don't make specific performance-multiplier claims, since actual impact depends heavily on the specific application's architecture and usage patterns.
React Native Features and Their Business Value
Feature scope should reflect what your specific users need to accomplish — adding capability without a clear user or business justification adds development and maintenance cost without proportional value.
| Feature | Why It Matters |
|---|---|
| User registration & login | The entry point for personalized experiences and secure data access |
| Social authentication | Reduces signup friction where appropriate to the user base |
| User profiles & role-based access | Personalizes the experience and controls what different users can see or do |
| Push & in-app notifications | Drives re-engagement and delivers timely information |
| Search & filters | Reduces friction navigating large content or product sets |
| Messaging | Supports in-app communication rather than routing users to external tools |
| File uploads, camera & photo library access | Enables document capture, profile photos, and content-driven workflows |
| Location, GPS & maps | Powers delivery tracking, nearby search, and location-aware features |
| Biometrics | Enables fast, secure authentication using Face ID or fingerprint sensors |
| Payments & subscriptions | Enables monetization or transactional workflows within the app |
| Shopping carts, orders & booking | Supports commerce and reservation-based workflows |
| Reviews & ratings | Builds trust and provides product/service feedback signals |
| Offline functionality | Keeps critical workflows usable without reliable connectivity |
| Admin dashboards | Gives business teams visibility and control over app data |
| API integrations | Connects the app to the broader systems a business already runs on |
React Native UI/UX Development
Good React Native UI/UX is built through deliberate design work, not ad-hoc component assembly:
- Reusable components — a shared component library that keeps the UI consistent and reduces duplicate work as the app grows
- Responsive layouts — adapting cleanly across the range of screen sizes within each platform
- Platform-specific UI — respecting Android's Material Design conventions and iOS's Human Interface Guidelines where platform-native feel matters
- Accessibility — ensuring the app is usable with screen readers, adequate touch target sizing, and appropriate color contrast
- Touch interactions — gestures and interaction patterns that feel natural for mobile use
- Typography and navigation — consistent, legible type systems and navigation patterns appropriate to the app's information architecture
- Onboarding — helping new users understand the app's value without excessive friction
- Forms, error states, loading states, and empty states — designed deliberately, since these commonly occurring states significantly affect perceived app quality
- Design systems — a governing set of components, spacing, and typography rules that keep the app visually coherent as it grows
- Animations — used purposefully to communicate state changes and improve perceived responsiveness, not as decoration
React Native supports building a UI that feels consistent across platforms while still respecting platform-specific conventions where users genuinely expect them — the framework doesn't force a choice between identical everywhere and fully native feel everywhere.
React Native Backend & API Development
Most React Native applications depend on backend services rather than functioning entirely on-device. Backend development typically covers:
- REST APIs, and GraphQL where a project benefits from flexible, client-driven data queries
- Authentication and authorization — verifying identity and controlling access to protected resources
- Databases structured around the app's actual data model and usage patterns
- Business logic — server-side rules governing application behavior
- File storage — for user-uploaded images, documents, or media
- Notifications — server-side infrastructure triggering push notifications based on app events
- Webhooks — for real-time, event-driven communication with external systems
- Third-party APIs — connecting the app to external services and platforms
- Logging and monitoring — visibility into backend behavior, errors, and performance
Backend technology selection depends on project requirements: Node.js and Express for JavaScript-consistent full-stack development, PHP and Laravel where hosting environment or team expertise favors it, and databases like PostgreSQL, MySQL, or MongoDB chosen based on how structured or flexible the application's data model needs to be.
React Native API Integrations
React Native apps frequently need to connect to external systems and services. Integration work typically covers:
- REST APIs and GraphQL as the standard integration layer
- Payment gateways for in-app transactions
- Maps for location-based features
- Analytics platforms for usage and engagement tracking
- CRM systems — pushing customer or lead data captured through the app
- ERP systems — syncing operational or inventory data
- Ecommerce platforms — connecting a mobile shopping experience to product and order data
- Accounting systems — reducing manual transaction reconciliation
- Shipping platforms — for delivery and fulfillment tracking
- Communication platforms — for in-app or transactional messaging
- Customer support systems — surfacing help content or tickets within the app
- Internal business systems — connecting mobile workflows to existing operational software
Technically, integration work involves authentication, data mapping, synchronization logic, retries and webhook handling, error handling, logging, and API versioning awareness. We don't claim specific completed integrations beyond what's verified for a given engagement.
React Native Native Module Development
React Native's JavaScript layer covers most application needs, but some functionality requires direct access to native Android or iOS code — this is where native module development comes in.
When native modules are useful:
- Accessing device hardware or SDKs not exposed by React Native's core libraries or well-maintained community packages
- Integrating with platform-specific services — Bluetooth connectivity, specialized camera controls, background services, or biometric authentication flows
- Wrapping an existing native SDK for use within a React Native app
- Achieving performance characteristics for specific operations that benefit from native-level execution
Technical approach:
- Android native modules are typically written in Kotlin, with Java used where a project's existing codebase requires it
- iOS native modules are typically written in Swift, with Objective-C used where integration with existing Objective-C code is necessary
- Native modules expose native functionality to the JavaScript layer through React Native's module system — traditionally via the bridge, and increasingly via TurboModules under the New Architecture
- Common use cases include camera and hardware integration, Bluetooth connectivity, biometric authentication, background services, push notification handling, and wrapping platform-specific SDKs
Native module development requires genuine platform-specific engineering knowledge — Kotlin/Java for Android, Swift/Objective-C for iOS — in addition to React Native expertise.
React Native Security
Security is addressed throughout the development lifecycle, not as a final pre-launch step. Our approach covers:
- HTTPS enforcement for all network communication
- Secure authentication with proper session and token expiration handling
- Authorization ensuring users only access what they're permitted to
- Secure token storage — using Keychain on iOS and Android's secure storage APIs, rather than plain local storage
- Encryption for sensitive data, both in transit and, where appropriate, at rest
- API security — authentication, rate limiting, and input validation on every endpoint
- Input validation across all forms and data entry points
- Access control appropriate to user roles and permission levels
- Dependency management — keeping React Native, native modules, and third-party libraries patched against known vulnerabilities
- Secure logging that avoids capturing sensitive data
- Vulnerability management — ongoing monitoring for newly disclosed issues in dependencies
- Biometric authentication, implemented using platform-native APIs for secure, low-friction login
Security is addressed across architecture, development, testing, and deployment — not treated as a checklist item at the end. We do not claim compliance with HIPAA, PCI DSS, SOC 2, or ISO 27001 unless specifically verified for a given engagement.
React Native Performance Optimization
Performance directly affects user experience and app retention. Key considerations specific to React Native include:
- JavaScript thread vs. UI thread — blocking the JavaScript thread can cause visible UI lag
- Unnecessary re-renders — addressed through careful component structure and memoization
- Memoization — using React.memo, useMemo, and useCallback deliberately
- List optimization — using FlatList or similar virtualized list components correctly for long scrollable lists
- Image optimization — appropriately sized and cached images
- Lazy loading — loading screens and heavy components only when needed
- Caching — reducing redundant network requests for data that doesn't change frequently
- API optimization — efficient backend calls that don't block perceived app responsiveness
- Memory usage — managing memory carefully, particularly for image-heavy or list-heavy screens
- Startup performance — minimizing the time from app launch to usable interface
- Native modules, used where JavaScript-layer performance genuinely isn't sufficient
- Hermes — React Native's JavaScript engine optimized for mobile, where appropriate for the project
- Performance monitoring — ongoing visibility into real-world app performance
We don't promise specific performance scores, since real-world performance depends on device conditions, network environment, and actual usage patterns.
React Native Testing & QA
Thorough testing matters given the range of devices and OS versions React Native apps run across. QA typically covers:
- Unit testing — verifying individual functions and logic in isolation
- Component testing — validating that individual UI components render and behave correctly
- Integration testing — confirming that components, state management, and API calls work correctly together
- End-to-end testing — validating complete user flows through the actual app
- API testing — validating backend endpoints independent of the frontend
- Regression testing — ensuring new changes don't break existing functionality
- UI testing — checking visual consistency and correct behavior across screen sizes
- Android testing and iOS testing — both need dedicated testing attention
- Device testing — across a representative range of physical devices
- Performance testing — under realistic device and network conditions
- Security testing — reviewing authentication, data handling, and API security
- Usability testing — validating that real users can complete key workflows
- Network-condition testing — verifying app behavior under slow, intermittent, or offline connectivity
- Crash monitoring — identifying and resolving stability issues in production
We select testing tools and frameworks appropriate to the project's stack and requirements rather than defaulting to a fixed toolset regardless of fit.
React Native Deployment
Android deployment
Involves the Google Play Console, including application signing, building release builds, using testing tracks before full release, and managing app versioning across releases.
iOS deployment
Involves App Store Connect, including certificates and provisioning profiles, TestFlight for beta distribution, and release management appropriate to your rollout strategy.
Beyond platform-specific submission, deployment also involves:
- Environment configuration — managing distinct settings for development, staging, and production environments
- CI/CD — automated build and deployment pipelines that make releases reliable and repeatable
- Staging — a pre-production environment for final validation before release
- Production — the live environment your users actually interact with
- Monitoring — post-release visibility into app health, crashes, and performance
We prepare and support submissions for both platforms, but we don't guarantee App Store or Google Play approval — review outcomes depend on each platform's specific policies at the time of submission.
Expo vs. React Native CLI
| Factor | Expo | React Native CLI / Bare Workflow |
|---|---|---|
| Development speed | ||
| Native access | ||
| Configuration | ||
| Build process | ||
| Libraries | ||
| Custom native modules | ||
| Team requirements | ||
| Project complexity | ||
| Maintenance |
Neither approach is universally better. Expo has matured significantly and now supports most native module needs through EAS Build and config plugins, making it a strong default for many projects. The bare React Native CLI workflow makes more sense for applications with extensive, complex native customization requirements. We assess this based on your specific feature requirements during discovery.

React Native MVP Development
MVP development in React Native focuses on validating a product idea with the smallest reasonable feature set:
- MVP scope — the minimum set of features that still delivers real value and tests your core assumption
- Core workflows — focusing engineering effort on the one or two flows that matter most
- Feature prioritization — separating what's essential from what can be added after validation
- Validation — building specifically to learn whether your core hypothesis holds
- Analytics — instrumented from day one so early usage data informs what to build next
- Feedback — creating mechanisms to learn from real users quickly
- Iterative releases — treating the MVP as a starting point that evolves based on real usage
- Scalable architecture — building the technical foundation so a validated MVP can grow without a full rebuild
React Native is particularly useful for startups that want to reach both Android and iOS users while sharing substantial application logic across platforms, keeping engineering cost lower than maintaining two separate native codebases during the validation phase.
Enterprise React Native Development
Enterprise React Native applications serve internal or business-critical functions, which shifts the technical priorities:
- Employee, customer, field-service, and partner applications — each with distinct access and workflow requirements
- Logistics applications — dispatch, delivery tracking, and driver-facing tools, often with offline requirements
- Internal workflow applications — digitizing processes that currently run manually
- Secure authentication and role-based access — critical for apps handling sensitive business or customer data
- ERP and CRM integrations — connecting mobile workflows to core business systems
- Reporting — giving management visibility into field or operational activity
- Offline functionality — essential where connectivity can't be assumed
- Centralized administration — managing users, permissions, and content across the organization
- Scalability and monitoring — supporting real usage volume with visibility into system health
Enterprise-specific technical challenges in React Native include managing native module dependencies across a larger codebase, coordinating React Native version upgrades across a team, and ensuring the shared codebase strategy doesn't create bottlenecks when platform-specific requirements diverge significantly.
React Native App Migration
Migrating to React Native — from native Android, native iOS, an older React Native version, or a legacy hybrid framework — requires careful assessment before any code is written:
- Technical audit — understanding the existing application's architecture, dependencies, and functionality
- Dependency analysis — identifying which native modules, libraries, or platform-specific code need equivalents
- Architecture assessment — evaluating whether the existing app's structure can inform the new architecture
- Migration strategy — deciding between a full rewrite and an incremental approach based on audit findings
- Incremental migration — where feasible, migrating screen-by-screen or feature-by-feature
- Testing — validating that migrated functionality behaves correctly against the original application
- Release planning — a controlled rollout that manages risk during the transition
- Rollback considerations — planning for the possibility that a migration phase needs to be reversed
We don't recommend a migration approach without first auditing the existing application — the right strategy depends heavily on what's actually in the current codebase.
React Native App Modernization
Applications running on outdated React Native versions accumulate specific, recognizable problems:
- Outdated dependencies — libraries that haven't been updated, sometimes with known security vulnerabilities
- Old architecture — apps built before the New Architecture missing its performance and native-integration benefits
- Poor performance — often from unaddressed re-render issues, unoptimized lists, or outdated native module implementations
- Inconsistent UI — accumulated design debt as features were added without a governing design system
- Technical debt — shortcuts taken under deadline pressure that make ongoing development slower and riskier
- Security issues — accumulated over time as dependencies age without updates
- Outdated APIs — both the app's own API layer and third-party integrations that may have changed
- State management problems — state logic that's grown unwieldy without a clear governing pattern
- Testing gaps — insufficient test coverage that makes changes riskier than they should be
- CI/CD improvements — manual or fragile deployment processes that could be automated
Modernization vs. rebuilding depends on the state of the existing codebase. If the architecture is fundamentally sound but outdated, targeted modernization is often more cost-effective than starting over. If technical debt has accumulated to the point where the existing architecture actively works against further development, a full rebuild may ultimately cost less.
React Native App Maintenance
React Native applications need ongoing technical attention because both the framework and its dependencies evolve continuously:
- React Native upgrades — new versions bring performance improvements, bug fixes, and eventually deprecate older APIs
- React upgrades — React Native's underlying React version also needs periodic updates
- Dependency updates — third-party libraries and native modules need regular maintenance
- Android OS changes and iOS changes — both platforms release regular updates that can affect app behavior
- Bug fixing — addressing issues that surface in real-world production use
- Security updates — patching newly discovered vulnerabilities in the framework or dependencies
- Performance monitoring — catching degradation before it affects users broadly
- Crash monitoring — identifying and resolving stability issues quickly
- API changes — third-party services and integrations evolve their own APIs over time
- Feature enhancements — ongoing development as business needs and user feedback evolve
Maintenance is essential for long-term application reliability because React Native's ecosystem moves quickly — falling significantly behind on versions makes future upgrades progressively harder and riskier.

As with our US engagements, Canadian projects are handled remotely across discovery, development, and post-launch support.
React Native App Development Cost
How much does React Native app development cost? Cost depends primarily on application complexity, the scope of native module development required, and backend/integration depth — not a single flat rate. Key cost drivers include:
- Overall application complexity and number of distinct features
- UI/UX complexity, including custom design vs. simpler interface patterns
- Whether both Android and iOS are targeted simultaneously
- Backend requirements and API development scope
- Third-party integrations (payments, ERP, CRM, analytics, etc.)
- Authentication complexity, including social or biometric login
- Payment and subscription functionality
- Location services and mapping features
- Messaging or real-time communication features
- Admin dashboard requirements
- Native module development, where platform-specific functionality is required
- Security requirements appropriate to data sensitivity
- Testing scope, including device and OS coverage
- Deployment and app-store submission support
- Ongoing maintenance needs
As a general industry reference point, a simple MVP with a narrow feature set typically represents a smaller investment than a full-featured business application with multiple integrations, which in turn is smaller than an enterprise application with extensive native module development and deep system integration. These are approximate industry patterns rather than The Runner Software Solutions pricing — actual cost depends entirely on your specific scope, confirmed through discovery.
React Native Development Timeline
How long does React Native development take? Timeline depends heavily on scope. As general reference points:
- A simple MVP with a focused feature set typically has a shorter development cycle than a full-featured application
- A standard business application with moderate integrations generally requires more time to account for backend development and testing
- An ecommerce application involves added complexity around payments, catalogs, and order management, typically extending the timeline
- A complex enterprise application with extensive native module development, integrations, and strict security requirements generally requires the longest timeline
We don't promise fixed delivery dates upfront — a realistic timeline is confirmed after requirements are defined during discovery.
React Native vs. Flutter
Neither framework is universally superior — the right choice depends on team background, UI requirements, and how the mobile app fits into your broader technology stack.
| Factor | React Native | Flutter |
|---|---|---|
| Programming language | ||
| UI approach | ||
| Ecosystem | ||
| Code reuse | ||
| Native integration | ||
| Performance considerations | ||
| Development workflow | ||
| Team skills | ||
| Libraries | ||
| Maintenance | ||
| Long-term considerations |
React Native makes sense when your team has existing JavaScript or React expertise, when you want to share concepts with a web application, or when you want to draw on JavaScript's very large talent pool. Flutter may make more sense when pixel-perfect, highly consistent UI across platforms is a priority.
React Native vs. Native Development
React Native is a strong choice for most business applications that need to reach both Android and iOS users. Native development may be preferable for applications requiring maximum performance or immediate access to brand-new platform capabilities.
| Factor | React Native | Native Android | Native iOS |
|---|---|---|---|
| Performance | |||
| Code sharing | |||
| Platform-specific APIs | |||
| Development effort | |||
| UI consistency | |||
| Native capabilities | |||
| Maintenance | |||
| Testing | |||
| Long-term considerations |
We assess this against your specific requirements rather than defaulting to either approach.

Frequently Asked Questions
React Native development is the process of building mobile applications using React Native — a framework that lets developers write application logic and UI in JavaScript or TypeScript, using React's component model, while rendering to genuine native UI components on Android and iOS. This produces a single, largely shared codebase that runs on both platforms, with the ability to integrate native Kotlin/Swift code when a feature requires direct platform access. React Native development covers UI, state management, backend/API integration, native module development, and app-store deployment for both platforms.

For businesses weighing React Native against other mobile approaches, our broader mobile app development service covers native iOS, native Android, and Flutter as well, and our Flutter app development service is worth a look if pixel-consistent cross-platform UI is your top priority.
