Introduction to App Development - by Daniel Walasinski (Paperback)

About the Book

15-chapter beginner app development textbook with step-by-step screenshots covering Figma, React Native, Expo, AI coding tools, device testing, Google Play, and Apple App Store publishing.

Book Synopsis

Introduction to App Development is a hands-on guide for learning how apps are designed, built, tested, and published.

This book introduces app development through a practical, make-first approach. Instead of beginning with long theory, the lessons guide learners through small working projects that can be created, tested, revised, and shared. The book begins with online tools such as CodeSandbox and Snack Expo, then moves into AI-assisted development platforms including Bolt.new and Cursor. From there, it introduces local and cloud-based development with Visual Studio Code, GitHub Codespaces, Python, Swift, Xcode, React Native, Expo, Figma, FlutterFlow, and Storyboard.

Each chapter focuses on a real part of the app development process: creating simple apps, improving user interfaces, converting designs into code, testing on real devices, preparing app assets, building production files, and publishing through Google Play and the Apple App Store. The lessons are written for beginners, but the workflow reflects how modern software projects are actually developed: design, code, test, troubleshoot, revise, build, and publish.

This book is especially useful for computer science teachers, high school learners, first-year app development students, and educators building a project-based technology course.

By the end of the book, readers will have explored web, desktop, mobile, and cross-platform development while gaining a clear understanding of the full app development pipeline.
