Map your product across the four Hook cycle phases: identify external and internal triggers, define the simplest possible action, create variable rewards (tribe, hunt, or self), and build user investment that increases switching costs. Then score each phase and improve the weakest link first.

The Hooked Model is a four-phase framework for building products users return to habitually. The cycle runs Trigger, Action, Variable Reward, and Investment, where each completed loop strengthens the habit and shifts users from external to internal triggers.

Variable rewards work because unpredictability sustains engagement, unlike predictable rewards that become boring. Use three types: tribe rewards like likes and comments, hunt rewards like new content or deals, and self rewards like progress and mastery.

Avoid hook-based design when the product does not genuinely improve users' lives, when users are the product rather than the customer, or when the design relies on dark patterns. Apply the manipulation test before implementing any engagement loop.

The Fogg Behavior Model (B = MAT) informs the Action phase of the Hook cycle. For habitual behavior, motivation must exist, ability must be high meaning the action is simple, and a trigger must be present.
