If you already build web apps with Next.js and Astro, you have a head start. This guide will help you learn mobile development so you can build and sell apps. We will use simple language and plenty of links and resources to help you along the way.
1. Pick a Mobile Framework
Since you know React from your web work, the best place to start is with React Native. It lets you build mobile apps for both Android and iOS using the same ideas as React. You can also use Expo which makes the process easier.

Tip: Later, you might try Flutter if you want to learn a new language (Dart).
2. Set Up Your Development Environment
Before you write any code, get your tools ready.
- Node.js & npm: You already have these from your web projects. Download Node.js.
- Expo CLI: Install it with this command in your terminal:
npm install -g expo-cli
-
Emulators and Devices:
- For Android, use Android Studio.
- For iOS, use Xcode if you have a Mac.
