Had to buy this to find out what I am supposed to do now that I am trying to help with design ... something I have never done before ... and this book is not only informative with everything so well explained and illustrated, but also very intresting. Who would have ever thought that a 64 year old could get interested in something so technichal, especially after being a housewife for over 40 years and barely being able to use a computer!!!!
All the important stuff you need to know about designing an iPhone app in one place. Informally written with loads of screenshots given as examples. Several case studies talk in more detail about some popular iPhone apps. Each section covers a different aspect of the app experience.
There's no coding in here, so it's all about user interface and user experience, but that's not a bad thing as there are already plenty of books that cover the programming side of iPhone app development.
If you're starting iPhone development, this book should be read.
