Hooked Ux

A solid implementation of Nir Eyal's Hook Model for anyone building engagement loops or trying to figure out why users aren't coming back. It walks through the four phases (Trigger, Action, Variable Reward, Investment) with specific product applications and scoring rubrics. The skill shines when you're designing notification strategies, building streak systems, or diagnosing post-signup drop-off. It includes ethical boundaries, which is refreshing, and the emphasis on reducing friction over increasing motivation is practical. The copy patterns and context-specific examples make it immediately applicable rather than theoretical. Best used when you need to systematically evaluate or design retention mechanics, not just sprinkle gamification on top of a product.

Hook Model Framework

Framework for building habit-forming products. Habits are not created — they are built through successive cycles through the Hook.

Core Principle

The Hook Model = a four-phase loop that connects the user's problem to your solution frequently enough to form a habit, moving usage from deliberate to automatic.

Trigger → Action → Variable Reward → Investment
