For the past few years, I've been on and off writing a book about mobile app development, from ideation to launch. Because I can only write about what I'm familiar with, I'm calling the book Opinionated Launch.<p>The book is sort of done, but "few years" is eons in software, so I'm now refreshing its content here and there. Since it's Black Friday, and I want to get early feedback, I'm doing a pre-order (with a steep discount).<p>If you have the time, please check the sample chapter here: <a href="https://opinionatedlaunch.com/Opinionated-Launch-sample-chapter.pdf" rel="nofollow noreferrer">https://opinionatedlaunch.com/Opinionated-Launch-sample-chap...</a> (you'd get this upon signing up for the newsletter, but I'll save you the hassle)<p>If you like it but are still deciding, please sign up for the newsletter. But if you want to support me and maybe influence the book, I'd be very happy if you pre-order.
