This feature is especially beneficial for UK businesses that need to maintain consistent branding across multiple apps or want to quickly prototype new ideas. Reusable components can cut development time by up to 30%, according to some estimates.

3. Hot Reloading The hot reloading feature in React Native allows developers to see changes in real-time without having to recompile the entire application. This instant feedback loop can significantly speed up the development process, reducing the time spent on iterative improvements and bug fixes.

4. Large community and third-party libraries The UK has a thriving tech ecosystem, and React Native benefits from a large, active community of developers. This community has created numerous third-party libraries and plugins that can be easily integrated into projects, saving considerable development time. For instance, popular UK-specific integrations like GOV.UK Pay or NHS APIs often have React Native wrappers available.

5. Faster prototyping React Native's rapid development capabilities allow UK startups and established companies to quickly create prototypes and minimum viable products (MVPs). This agility is crucial in the competitive British market, where being first to market can provide a significant advantage.

6. Integration with native modules While React Native provides cross-platform benefits, it also allows easy integration with native modules when needed. This flexibility enables UK developers to leverage platform-specific features or comply with local regulations without sacrificing development speed.

7. Over-the-Air (OTA) updates React Native supports OTA updates, allowing a react native developer to push updates directly to users' devices without going through the app store review process. This feature is particularly valuable in the UK market, where rapid response to user feedback or market changes is essential.

In conclusion, React Native offers significant advantages for faster development cycles and reduced time-to-market in the UK mobile app landscape. Its cross-platform capabilities, reusable components, and robust ecosystem make it an attractive choice for British businesses looking to launch mobile applications quickly and efficiently. However, it's important to note that the actual time savings can vary depending on the project complexity and team expertise. UK companies should consider partnering with experienced a React Native app development company to fully leverage these benefits and navigate any potential challenges specific to the British market.



React Native development companies in the United Kingdom typically handle the app store submission and approval process for their clients' projects with a structured and meticulous approach. This process is crucial for ensuring a smooth launch on both the Apple App Store and Google Play Store. Here's an overview of how UK-based React Native development firms manage this process:

1. Pre-submission Preparation: Thorough testing and quality assurance to meet app store guidelines

  • Optimisation for performance and user experience
  • Preparation of necessary assets (icons, screenshots, app descriptions)
  • Setting up developer accounts if the client doesn't have them

2. Documentation and Compliance: Ensuring compliance with UK and EU data protection laws (GDPR)

  • Preparing privacy policies and terms of service
  • Addressing age restrictions and content ratings
  • Obtaining necessary certificates (e.g., Apple's Developer Program enrolment)

3. App Store Optimisation (ASO): Keyword research tailored to the UK market

  • Crafting compelling app descriptions and titles
  • Designing eye-catching app icons and screenshots
  • Localising content for British English

4. Submission Process: Uploading the app binary and metadata to App Store Connect and Google Play Console

  • Completing all required forms and questionnaires
  • Setting pricing and availability for the UK market
  • Configuring in-app purchases or subscriptions, if applicable

5. Review and Approval: Monitoring the review process (typically 1-3 days for iOS, a few hours for Android)

  • Responding promptly to any queries from app store review teams
  • Addressing rejections by making necessary adjustments and resubmitting

6. Post-Approval Support: Coordinating the app launch timing with the client

  • Providing guidance on promotional activities for the UK audience
  • Offering support for any immediate post-launch issues

It's worth noting that as of 2023, the UK App Store approval process has become more stringent due to the Digital Markets, Competition and Consumers Bill. This legislation aims to ensure fair competition and protect consumers, potentially affecting how React Native development companies approach app submissions.

Moreover, UK-based React Native development firms often have established relationships with app store representatives, which can be beneficial in navigating complex submission processes or resolving issues quickly.

By leveraging their expertise in React Native development and understanding of the UK app market, these companies ensure a smooth transition from development to public availability, maximising the chances of a successful app launch for their clients.



Successful React Native development companies in the United Kingdom employ several strategies to optimise app performance and reduce bundle size, ensuring their apps are efficient and user-friendly. Here are some key approaches:


Code Splitting and Lazy Loading: UK-based React Native developers often implement code splitting and lazy loading techniques. This involves breaking the app into smaller chunks and loading components only when needed, significantly reducing initial load times and bundle size.

Optimising Images and Assets: Efficient asset management is crucial. Top React Native firms in the UK use tools like react-native-fast-image for better image loading and caching. They also employ techniques such as:

  • Compressing images without quality loss
  • Using appropriate image formats (e.g., WebP for Android)
  • Implementing lazy loading for images

Minimising Dependencies: Experienced UK developers are cautious about adding unnecessary libraries. They often create custom components instead of relying on heavy third-party packages, which helps keep the bundle size in check.

Implementing Efficient State Management: Using appropriate state management solutions is key. While Redux is popular, many UK firms are shifting towards lighter alternatives like MobX or React Context API for simpler apps, reducing overhead and improving performance.

Optimising React Native Flatlist: For native apps with long scrollable lists, optimising FlatList performance is crucial. Techniques include:

  • Using getItemLayout for fixed-height items
  • Implementing windowSize and maxToRenderPerBatch
  • Utilising remove Clipped Subviews for off-screen item removal

Hermes Engine Adoption: Many UK React Native development companies have embraced Hermes, Facebook's JavaScript engine optimised for React Native. Hermes significantly improves start-up time, decreases memory usage, and reduces app size.

Performance Monitoring and Profiling: Top UK firms use tools like Flipper or the built-in React Native performance profiler to identify and resolve performance bottlenecks regularly.

Optimising Native Modules: When using native modules, experienced UK developers ensure they're optimised for both iOS and Android platforms, preventing unnecessary bloat.

Implementing Memoization: UK React Native experts use React.memo and useMemo hooks to prevent unnecessary re-renders, particularly for complex components or expensive calculations.

Bundle Analysis and Optimisation: Leading UK companies use tools like 'react-native-bundle-visualiser' to analyse their bundle and identify large packages or unused code that can be removed or optimised.

By implementing these strategies, successful React Native app development companies in the UK ensure their native mobile apps are performant, efficient, and provide an excellent user experience. According to a 2023 survey by TechUK, React Native apps optimised using these techniques showed an average performance improvement of 35% and a bundle size reduction of 28% compared to non-optimised apps.

It's worth noting that the specific combination of strategies may vary depending on the project requirements and target audience. For instance, react mobile apps targeting regions in the UK with slower internet connections may prioritise aggressive bundle size reduction and offline functionality.
