If you want to build mobile apps for both iPhone and Android without writing two separate codebases, React Native is one of the most popular ways to do it. React Native lets developers use JavaScript and React to create real mobile apps that feel native—meaning they run like apps built specifically for each platform.

What Is React Native?
React Native is a framework developed by Meta that allows you to build mobile apps using React.
In Simple Terms:
👉 React Native = React for mobile apps
Instead of building:
- iOS apps with Swift
- Android apps with Kotlin
You can build both using one codebase.
What Does React Native Do?
React Native allows developers to:
- Build mobile apps using JavaScript
- Share code between iOS and Android
- Create fast, smooth user interfaces
- Access device features like camera, GPS, and notifications
What React Native Code Looks Like
Here’s a simple example 👇
import React from "react";
import { Text, View, Button } from "react-native";export default function App() {
return (
<View>
<Text>Hello React Native</Text>
<Button title="Click Me" onPress={() => alert("Hello!")} />
</View>
);
}
Key Differences: React vs React Native
| Feature | React | React Native |
|---|---|---|
| Platform | Web (websites) | Mobile (iOS & Android) |
| Components | <div>, <h1> | <View>, <Text> |
| Styling | CSS | JavaScript styles |
| Output | Browser UI | Native mobile UI |
Apps That Use React Native
- Uber Eats
- Discord
👉 These apps use React Native for parts of their mobile experience.
Why Developers Use React Native
✅ Pros
- One codebase for both platforms
- Faster development time
- Large community and support
- Reusable components
- Lower cost compared to building two separate apps
❌ Cons
- Not ideal for very complex native features
- May need native code for advanced performance
- Debugging can sometimes be tricky
How React Native Works
Instead of rendering to a browser like React, React Native:
- Uses native components (real mobile UI elements)
- Bridges JavaScript code to native APIs
- Updates the screen efficiently
👉 Result: Apps feel like real native apps, not web apps.
What You Can Build With React Native
- Social media apps
- Messaging apps
- eCommerce apps
- Productivity tools
- Business apps
How This Connects to Your Wakewall App
Since you’re building Wakewall with Android (Kotlin), React Native could:
- Help you build an iOS version faster
- Allow shared logic across platforms
- Speed up development for new features
👉 Many startups use React Native to launch on both platforms quickly.
React Native vs Kotlin
If you’re using Kotlin:
- Kotlin = best for pure Android performance
- React Native = best for cross-platform speed
👉 A hybrid approach is also possible:
- Keep core Android features in Kotlin
- Use React Native for shared UI features
How to Get Started
- Learn JavaScript basics
- Learn React fundamentals
- Install React Native tools (Expo or CLI)
- Build small apps (like a to-do app)
- Test on a real device or emulator
Final Thoughts
React Native is one of the most powerful tools for building mobile apps quickly and efficiently. If you want to reach both iOS and Android users without doubling your workload, it’s a smart choice. Whether you’re building a startup app like Wakewall or starting a side hustle, React Native gives you the flexibility to scale fast.
