“I thought mobile apps were only for pros. This book made it simple — I launched my first app in weeks.”
Build your first mobile app — no coding experience needed.
A beginner-friendly guide that takes you from zero programming knowledge to building and publishing cross-platform apps with React Native and Expo. Learn by doing, then finish with a complete app you can install and share.
Learn mobile app development the practical way — React Native & Expo from scratch
If you've never written a line of code, this book is for you. We start at the very beginning with JavaScript basics and build up in small, confident steps until you can create and style screens, handle user input, fetch data from APIs, and publish to the app stores.
You'll learn by reading, typing, and testing — no complex setup beyond a free editor, Node.js, and the Expo Go app on your phone.
You'll practice how to:
- Write and understand JavaScript: variables, functions, arrays, objects, and loops.
- Use React concepts: components, props, state, and hooks.
- Style with Flexbox and React Native's style system.
- Build multi-screen apps with navigation.
- Fetch and display live data from APIs.
- Handle images, icons, and custom fonts.
- Store data locally for offline use.
- Ship a final project: plan, build, and publish a real app with Expo.
Each chapter ends with short exercises and mini-projects to reinforce learning.

Faruk Nasir – Hey there, I’m the author behind ‘React Native and Expo for Beginners - Build Your First Mobile App Step by Step’.
I run Starfolk Software and teach beginners how to build apps from scratch. I wrote this book to give you a straight path: learn JavaScript, pick up React, and apply it with React Native & Expo to ship a real mobile app you can show off. No fluff — just practical steps, real examples, and plenty of encouragement.
