Hooked written by Nir Eyal is the book everyone in silicon valley is talking about. The real reason that draws my attention is the book’s contributing writer, Ryan Hoover, who is the founder of Product Hunt.

After learning about the Hook Model, I realize that many successful apps are using these principles to build their Habit-Forming products. If you are building your products, make sure you follow the 4-step Hook Model – “Trigger”, “Action”, “Variable Reward”, “Investment”.
