who this book is for

This book has much to offer to both students and teachers:
  • For teachers, it walks through, in detail, all of the screens of the Touch Develop app, and it points out similarities and differences of the Touch Develop language compared to other programming languages that the teacher might already be familiar with.
  • For students and enthusiasts, the book can serve as a handy reference next to the phone.
The book systematically addresses all programming language constructs, starting from the very basics such as variables and loops. The book also explores many of the phone sensors and data sources which make creating apps for mobile devices so rewarding.

how to read this book

If you are new to programming with Touch Develop, or if you have not yet worked on touchscreen devices, we suggest that you read the book starting from chapter 1. If you are already familiar with the basic paradigm of the Touch Develop programming environment, then feel free to jump ahead to the later chapters that address particular topic areas.


The Touch Develop Web App runs in many modern browsers on many different devices such as iPhone, iPad, Android phones and tablets, Macs, PC.
