Complete Mobile Developer course with AI Projects (Udemy.com)

Become a job-ready mobile developer by building real apps with React Native and Expo | from your very first component to authentication, maps, and production builds.

Mobile is where users spend most of their time, yet skilled mobile developers are still in short supply. This course closes that gap. If you already know a little JavaScript and React, you'll learn how to turn that knowledge into real, installable Android and iOS apps using Expo - the modern, beginner-friendly framework built on top of React Native and trusted in production by apps like Instagram and Discord.

We start from the ground up: what mobile development is, how React Native compares to Expo, and how to set up your environment and ship your first project. From there you'll master the core components (View, Text, Image, TextInput, Pressable, StyleSheet), styling, props, and list rendering - then put them to work building real screens.

Next, you'll go deep into navigation - first with React Navigation, then with modern Expo Router file-based routing, including dynamic routes, catch-all segments, layouts, route groups, stacks, tabs, drawers, and modals. You'll learn how to talk to APIs (both your own Expo API routes and external services), and how to persist data using AsyncStorage, SecureStore, SQLite, and the file system.

The second half is all about going native. You'll work with device sensors (accelerometer, gyroscope, magnetometer, light sensor, pedometer), the camera and microphone, network, deep linking, haptics, and battery APIs, interactive maps with markers and polylines, and push notifications. You'll then implement complete authentication flows — protected routes, email/password login, Google and GitHub OAuth, and third-party providers like Better Auth and Clerk — and learn EAS development builds and app variants to get your app onto real devices.

To tie it all together, you'll build real-world capstone projects, including a Weather app (Expo Location, live weather/forecast/AQI APIs, custom hooks, and dynamic backgrounds), a Pinterest-style Pixabay wallpaper app (search, color & category filters, detail modals, and image downloads), and a standout AI Story Generator that uses the AI SDK and OpenRouter to generate stories and images from a single prompt — routing requests to models like OpenAI, Gemini, and Claude with structured, Zod-validated output, plus local storage and dark mode.

Throughout the course you'll also cement every concept with hands-on mini-projects, including a Profile Card Gallery, a Pokédex app, a Notes Buddy storage app, a News Feed reader, a Tilt-the-Ball sensor game, a Profile Pic Creator, and a Reminder Buddy notifications app.

By the end, you won't just understand Expo — you'll have built a portfolio of real apps (including an AI-powered one) and the confidence to design, build, and ship your own mobile products. Enroll now and start building.
