What is the hook model? How to build habit-forming products

Habit-forming products, like Spotify, are characterized by low churn rates and high lifetime value due to their ability to build strong user habits through the hook model, as described in Nir Eyal's "Hooked: How to Build Habit-Forming Products." This model involves a cycle of triggers, actions, variable rewards, and user investment, which collectively facilitate habit formation by making users return regularly. Triggers, both internal and external, initiate actions that provide variable rewards, while user investment enhances future rewards and increases attachment to the product. Ethical considerations depend on the purpose of the habits being formed, with beneficial applications, such as educational tools like Duolingo, being seen as ethical. The hook model is a tool that can be used to enhance or harm user experiences, depending on its application, and LogRocket is a platform that provides insights into user behavior to improve product design and reduce friction in user experience.
