Hooked: How to Build Habit-Forming Products

A deep dive into what creates an habit and on how to build addictive apps / website, create new behaviors. This book is a must read for every app or website builder, or every person with an interest into building something that users will come back to use often. I really like the moral point of view offered at the end of the book, which shines a light into the entrepreneur's mission and gives a moral compass to follow.
