The App Design Handbook

Everyone has an idea for an iPhone app. Once
friends and family hear that you have any skills or
experience in that area you will quickly become the
sounding board for their new idea. While they think
the idea is the most important thing, you know that it
takes skill and time to turn that idea into a great
experience for the user.
That’s what this book is about: taking an idea from a rough concept to a
polished experience that your users will love. Whether you are a developer,
project manager, or just a hobbyist who wants to better understand
application design, this book will serve as a guide to designing great iOS
applications. It is written in a simple, practical manner, so that you don’t
need a technical or design background in order to follow along.
