The Hooked Model and How it Builds Habit Forming Applications

The Hooked model, conceptualized by Nir Eyal, offers a structured approach to creating habit-forming apps.

It revolves around four key steps that guide users through a loop of engagement: Trigger, Action, Variable Reward, and Investment

By understanding and implementing these four steps, developers can design apps that effectively capture users' attention and foster long-term usage.

1. Trigger:
   • Triggers prompt users to take action.
   • Two types: external triggers (e.g., notifications) and internal triggers (e.g., emotions).
   • Conduct A/B testing to optimize triggers.
2. Action:
   • Users perform a simple action in response to the trigger.
   • Make actions easy to perform for higher engagement.
   • Apply strategies like using bright colors and identifiable icons.
3. Variable Reward:
   • Users receive varied and unpredictable rewards after completing actions.
   • Rewards keep users engaged and eager for more.
4. Investment:
   • Users invest time, data, money, or effort in the product.
   • Increases the likelihood of users returning to the app.

Use A/B testing throughout to refine strategies and improve user experience
