Hooked:
How to Build Habit-Forming Products is a business book by Nir Eyal (with Ryan Hoover) that provides a framework for designing products that create user habits without relying on costly advertising.
Product Description
The core of the book is the Hook Model, a four-step cycle designed to subtly encourage customer behavior:
Trigger: External (notifications) or internal (emotional states) cues that prompt action.
Action: The simplest behavior done in anticipation of a reward, facilitated by ease of use.
Variable Reward: The user receives a payoff that varies in type or timing, satisfying a need while sparking curiosity.
Investment: The user puts effort into the product (data, time, money), increasing the likelihood of the next hook cycle.
