This book centralises the science of designing interfaces, void of any specific platform or device but rather allows the reader to think spatially in terms of UX for the thumb. The Mobile developer will be able to follow the various topics or 'best practices' in a familiar theme of Problem-> Solution, with commentary and options following that. Some of the topics are quite basic, stale and non-exciting but if you can follow the book and skip over sections you don't feel is appropriate for you, then this book accumulatively is great.
I recommend this book, because it forces developers and designers to go through the basics they thought was right, re-think that and adjust, rather than cut corners and dive into the excitement of mobile development. I would take my time and read each chapter on my down time and learn something new, rather than dedicate a whole chunk of my time in one go to it. It's the type of book that is a reference than a page-to-page necessity. If you are working on an iOS, Android or Mobile Web App, this book provides themes that are device-independent in a thoughtful, comprehensive and mechanical approach.
