Build iOS & Android Apps with One Codebase
React Native lets you write mobile apps in JavaScript/TypeScript and deploy to both platforms. Share business logic, reduce development time by 40-60%, and deliver native experiences.
Why React Native for mobile apps?
React Native enables you to build mobile applications for iOS and Android using JavaScript and React. Instead of maintaining two separate codebases (Swift for iOS, Kotlin for Android), you write once and deploy to both platforms. This doesn't mean compromised quality—React Native apps feel native because they use actual native components, not web views.
Companies like Facebook, Instagram, Shopify, Discord, and Microsoft use React Native for their mobile apps. The framework has matured significantly since its 2015 release, with improved performance, better tooling, and a massive ecosystem of libraries. For most business applications, React Native delivers the speed of cross-platform development without sacrificing user experience.
At Devionary, we've built React Native apps for e-commerce, fintech, healthcare, and logistics. We understand the trade-offs: when React Native is perfect, when you need platform-specific code, and how to structure projects for long-term maintainability. We use TypeScript for type safety, implement proper navigation patterns, handle offline sync, and optimize performance.
Advantages of React Native
Single Codebase
Write once, deploy to iOS and Android. Share 70-90% of code between platforms. Maintain one set of business logic, API clients, and state management.
Faster Development
Develop 40-60% faster than building separate native apps. Hot reload for instant feedback. Leverage web development skills and React ecosystem.
Native Performance
Uses native components, not WebViews. Smooth 60fps animations. Access to device features like camera, GPS, push notifications, and biometric auth.
Large Community
Backed by Facebook/Meta. Huge ecosystem of libraries and tools. Easy to find developers. Active community solving common problems.
Code Reuse with Web
Share business logic, utilities, and types between React Native app and React web app. Monorepo setups with shared packages.
Over-the-Air Updates
Push JavaScript updates without App Store review (via CodePush, Expo Updates). Fix bugs and ship features faster for non-native code changes.

When React Native is the right choice
You need both iOS & Android
If you're targeting both platforms, React Native's code sharing significantly reduces development time and maintenance costs compared to building two native apps.
Time to market matters
Startups and MVPs benefit from React Native's faster development cycle. Launch on both platforms simultaneously instead of building iOS first, then Android months later.
You have React developers
If your team knows React, they can build mobile apps with minimal learning curve. Share developers between web and mobile projects.
The app is business/CRUD focused
Forms, lists, API calls, authentication, chat, and typical business logic work perfectly in React Native. Not ideal for heavy graphics or AR/VR.
