Why do some products capture our attention while others flop? How do technologies hook us? Nir Eyal answers these questions (and many more) with the Hook Model - a four-step process that subtly encourages customer behaviour; repeatedly bringing them back without costly advertising or aggressive messaging.

Based on years of research, consulting, and practical experience, Hooked shows how to create user habits that stick. With practical insights and riveting examples, from the iPhone to Twitter, Pinterest and the Bible App, it's for product designers, marketers and anyone who seeks to understand how products influence our behaviour. It's the book Eyal wishes had been available to him as a start-up founder.
