React Native App Development Company
AI Nova Apps is a React Native app development company that helps startups and established businesses launch iOS and Android apps from one TypeScript codebase. React Native renders real native components, so your app looks and behaves like a native app while your team works with React — the technology behind most modern web products. It is one of the core frameworks used by our mobile app development team.
The New Architecture, in Plain Terms
React Native has been substantially rebuilt in recent years, and the New Architecture is now the default for new apps. Three parts matter to you as a product owner:
- JSI lets JavaScript call native code directly instead of passing messages over the old asynchronous bridge, removing a major source of lag.
- Fabric, the new renderer, supports modern React features such as concurrent rendering, so complex screens and gestures feel smoother.
- Turbo Modules load native modules only when they are needed, which helps startup time.
Together with the Hermes JavaScript engine, which precompiles code to bytecode, this closes much of the performance gap behind early React Native's mixed reputation. It also means older apps still on the legacy architecture need a planned migration, because new library versions increasingly support only the new one.
Expo or Bare React Native?
The official React Native documentation now recommends starting new apps with a framework such as Expo, and for most projects we do: Expo Router for file-based navigation and deep links, EAS Build and Submit for repeatable cloud builds and store uploads, and EAS Update for over-the-air fixes. Expo no longer limits native access — with development builds, config plugins and the Expo Modules API we can add any native SDK. We choose a bare setup mainly when React Native is being embedded into an existing native app or a client's build pipeline requires it.
Native Modules When JavaScript Isn't Enough
Some features need platform code: Bluetooth Low Energy devices, background location, a bank or KYC SDK that only ships for iOS and Android, on-device machine learning or heavy media processing. Our engineers write these modules in Swift and Kotlin with the Expo Modules API or Turbo Native Modules, expose a typed TypeScript interface to the rest of the app, and test them like any other code. iOS widgets, Live Activities and watch apps are built natively alongside the React Native app.
Sharing Code With Your Web App
For many companies, the biggest advantage of React Native is reuse. In a monorepo, your React or Next.js website and your mobile app can share TypeScript types, API clients, data-fetching hooks, validation rules and design tokens, so a pricing rule or form check is written once and behaves the same everywhere. Some screens can be shared through React Native for Web, though we keep SEO-critical pages in Next.js, where they rank best. Our web development team works in the same stack, which makes this practical rather than theoretical.
Over-the-Air Updates, Used Responsibly
EAS Update lets us ship JavaScript fixes to users within minutes instead of waiting for a store release, with separate channels for staging and production and quick rollback. Apple and Google permit this for bug fixes and small improvements as long as the update doesn't change the app's core purpose, so new native code and significant features still go through normal store review.
Rescue and Upgrade Existing React Native Apps
Many teams come to us with an app that has fallen behind: an old React Native version, slow lists, crashes or libraries that no longer build. We audit the codebase, upgrade step by step to the New Architecture, replace abandoned packages, fix performance bottlenecks with tools such as FlashList and Reanimated, and set up CI/CD and monitoring, so the app is stable and ready for new features again.
React Native vs Flutter vs Native
React Native is usually the best choice when you already have a React product or JavaScript team, or need to share logic between web and mobile. Flutter shines for highly custom, animation-heavy interfaces, while native iOS and Android development suits apps that push device hardware to the limit.

Web and Mobile With One Team
Because our engineers work across React, Next.js and Node.js, we can build your mobile apps, web application and backend APIs together, grow your platform into a full SaaS product, or add AI assistants built on large language models.
