What is the difference between React Native and native app development?

Native development creates separate applications using platform-specific technologies, while React Native allows teams to share much of the application code between iOS and Android. React Native can also use native modules when platform-specific functionality is necessary.

Can you build a React Native app from an existing website or web application?

Yes. An existing web product can provide useful business logic, API and design references, but the mobile experience should normally be designed around mobile navigation, interaction patterns, device capabilities, performance, and offline requirements rather than simply copying the website.

Should my React Native project use Expo or React Native CLI?

It depends on the application's technical requirements. Expo is highly useful for many products because it simplifies development and release workflows, while projects requiring extensive native customisation may benefit from a React Native CLI-based setup. We choose the approach according to the product rather than using one framework configuration for every project.

Can React Native access Bluetooth, GPS, camera and biometric features?

Yes. React Native applications can work with device capabilities such as location, camera, Bluetooth, biometrics, notifications and secure storage through established libraries or custom native integrations when required.

Can you migrate an existing native iOS or Android app to React Native?

Yes. We first assess the existing codebase, architecture, dependencies, integrations and native functionality. Suitable applications can then be migrated progressively or rebuilt in React Native while preserving important business functionality and improving maintainability.

How do you make React Native applications fast?

Performance is addressed throughout development through efficient component rendering, appropriate state management, optimised assets, network and API strategies, caching, list optimisation, memory management, native integrations where appropriate, and testing on representative devices.

Can you connect a React Native app to our existing backend?

Yes. React Native applications can integrate with existing REST or GraphQL APIs, authentication systems, databases, cloud services, payment platforms, CRMs, ERPs and other business systems. We can also develop or extend backend services where the existing infrastructure needs additional capabilities.

How do you handle React Native app updates after launch?

Post-launch support can include React Native and dependency upgrades, iOS and Android compatibility updates, bug fixing, crash analysis, performance improvements, security maintenance, new feature development, analytics review, and release management.

How long does it take to develop a React Native application in the UK?

A focused MVP may take several weeks, while a feature-rich production application can require several months. The timeline depends on product scope, design complexity, backend work, integrations, native functionality, testing requirements, and the size of the engineering team.

A React Native Partner Built Around Product Growth

React Native can reduce duplicated development work, but the real advantage comes from how the application is architected and maintained. Arramton combines cross-platform engineering with backend, cloud, UX, testing, and product development expertise to create applications that remain practical to operate as they grow.

Architecture Before Code

We evaluate product requirements, platform constraints, integrations, and future roadmap needs before deciding how the React Native application should be structured.

Shared Where It Makes Sense

Maximise reusable React Native functionality while introducing platform-specific Android or iOS code where the product genuinely requires native behaviour.

Production-Ready TypeScript

Use structured TypeScript, reusable components, clear application boundaries, and maintainable engineering practices designed to reduce technical debt.

Full-Stack Mobile Capability

Connect mobile applications with APIs, databases, authentication, cloud infrastructure, payment systems, analytics, AI services, and business platforms.

Performance as a Feature

Consider startup time, rendering, memory, network efficiency, caching, offline behaviour, and device compatibility throughout the development lifecycle.

Built for Continuous Releases

Create development and deployment workflows that allow teams to introduce improvements, fixes, and new functionality without turning every release into a major project.

React Native Engineering From Architecture to App Store

A complete React Native development capability covering technical strategy, interface engineering, backend connectivity, native functionality, testing, release management, and ongoing optimisation.

Architecture & Technology Consulting

Define the right React Native architecture, project structure, state management approach, API strategy, native requirements, and release workflow before engineering begins.

TypeScript & UI Engineering

Create maintainable TypeScript codebases, reusable components, responsive interfaces, design systems, navigation flows, animations, and accessible mobile experiences.

Native & Third-Party Integrations

Connect React Native applications with payments, maps, biometrics, notifications, cameras, Bluetooth, analytics, authentication providers, AI APIs, and enterprise platforms.

Migration, Maintenance & Scaling

Modernise existing applications, upgrade React Native versions, resolve technical debt, improve performance, add new capabilities, and support continued product growth.

From Product Idea To Production App

Our React Native workflow combines product thinking with disciplined mobile engineering so every release has a clear technical purpose, measurable progress, and a path toward long-term scalability.

Product & Technical Assessment

Define the target users, business objectives, core features, platform requirements, integrations, technical constraints, and success metrics.

Architecture Blueprint

Establish the React Native project structure, TypeScript strategy, navigation, state management, API layer, authentication, data flow, and native requirements.

Experience & Feature Development

Translate approved designs into reusable components and functional mobile experiences while connecting the application with backend and third-party services.

Device & Production Validation

Test critical workflows across devices and operating systems while evaluating performance, accessibility, security, network behaviour, and release readiness.

Launch, Monitor & Evolve

Release through the appropriate app stores, monitor application behaviour, address production issues, and continuously improve the product through subsequent versions.

React Native Development For Products That Need to Move Faster

Purpose-built React Native solutions for organisations that want shared development efficiency without sacrificing mobile performance, native functionality, or long-term maintainability.

React Native MVPs

Turn product concepts into functional iOS and Android MVPs with a focused feature set, reusable architecture, analytics, authentication, and production-ready foundations.

Consumer Mobile Products

Build customer-facing applications for marketplaces, subscriptions, communities, booking platforms, retail experiences, media products, and digital services.

Enterprise Workforce Apps

Develop secure applications for employees, field teams, sales organisations, operations departments, and distributed workforces with role-based functionality and connected workflows.

Real-Time Mobile Applications

Create applications requiring live status updates, messaging, location tracking, delivery visibility, alerts, notifications, and synchronised mobile experiences.

AI-Enabled React Native Apps

Add intelligent search, conversational interfaces, content generation, recommendations, automation, document processing, and other AI capabilities to mobile products.

Legacy App Modernisation

Assess and modernise ageing iOS, Android, or hybrid applications by introducing maintainable React Native architecture and reducing duplicated platform development.
