React Native Development Services In The UK

Minimum Viable Product (MVP) and prototype engineering is used to create a preliminary version of a digital product to test real market demand. Intellivita rapidly prototype and deploy a Minimum Viable Product or Proof of Concept (PoC) to help UK startups validate ideas and reduce time to market (TTM). Our engineers iterate on core features, test market response, and refine the product based on real user feedback. MVP and prototype engineering works best for startups and software companies who need fast validation, controlled spend, and product confidence.

UI/UX implementation transforms your product designs into responsive, functional interfaces using React Native. We translate Figma or Sketch files into pixel-perfect components styled with Flexbox and structured using scalable design systems. Our team renders Cupertino layouts for iOS and Material Design for Android to ensure platform-native consistency. We standardize components using Atomic Design principles and animate key interactions with Lottie for better user engagement. Product teams rely on UI/UX implementation and design systems for responsive layouts, reusable components, and brand-aligned delivery.

App migration is the process of re-platforming legacy mobile apps into React Native to improve performance and code maintainability. Experts at Intelivita migrate applications built in Objective-C, Java, Cordova, Ionic, or Flutter and rewrite them to match React Native standards. We preserve data integrity, port existing features, and ensure feature parity with the legacy version. We totally understand how migration is important to you, so we carefully plan it to reduce downtime, maintain user experience, and prepare your app for long-term scalability. UK businesses require app migration service to modernise the tech stacks without losing core functionality or market traction.

React Native for web development extends your mobile app codebase to the browser using React Native Web. Our team reuses shared components and unifies mobile and web interfaces through a single monorepo structure. We render responsive layouts directly to the DOM, enabling progressive web apps (PWA) and consistent user journeys across both mobile and desktop devices. We ensure reliable performance while maintaining brand and design consistency. React Native for Web Development helps startups, SMEs, and e-commerce companies accelerate web deployment. It also helps in reducing frontend duplication and deliver a unified multi-platform experience.

Performance optimization is used to improve app speed, stability, and responsiveness for better user experience. We profile existing apps to reduce startup time, identify frame drops, and remove memory leaks that affect the main thread and UI thread. We audit bundle size, minify and compress assets, and apply the Hermes engine where required in order to reach stable 60fps performance. With performance optimization of an app, our team protects user retention, app ratings, and product reliability. This service benefits businesses across different industries like retail, e-commerce, and real estate, to avoid slow times, crashes, and performance complaints.

App maintenance and support keeps your mobile app stable, secure, and up to date across OS versions. Our team at Intelivita monitors performance issues, fixes bugs, and applies security patches to avoid service interruptions. We upgrade libraries, manage dependency drift, and ensure compatibility with the latest iOS 18 and Android 15 updates. Using CodePush, we deploy OTA updates without waiting for app store approvals. App maintenance and support service helps UK businesses maintain product quality, protect user trust, and extend app lifecycle with minimal disruption.
