It takes me three weeks to read this book. Actually, I was not interested in this kind of book because I thought this should be some marketing problems. As an engineer, I used to think about how to write a good App but to introduce my App to others.
I really recommend this book for those people who gonna start their first Apps with out experience on selling stuff on Apps Store, and the people who encounter problems when marketing their Apps.
This book contains 10 chapters. The first four chapters are talking about how to settle your mind and how to prepare before you really start your Apps. The following three chapters are discussing about the marketing of your Apps. The last three chapters mentions some awareness people should know about their Apps.
There are many useful ideas in the book for those people just starting. For examples, you should name your Apps within 12 characters since that is the maximum characters can be showed on an iPhone, and you can give a brief free edition to test will the customers love your idea before you put all your mind on the development.
I like the Chapter 6 which is talking about the business model. It gives many useful ideas for observing the market environment. Different types of Apps models should have different strategies to sell well. It separates the business models as Content, Functionality, Services, and Subscription. Take subscription model as an example, you may give different periods for user to subscribe your Apps. If they like your Apps, they can buy a long term, or they can buy a short term for testing.
After all, I think it's a book for people who just starting their first Apps. It really helps if you want to earn some money from Apps Store.
