How do I actually improve retention and make my product habit-forming?

The short answer

Use the Hook Model: pair a trigger with an easy action, a variable reward, and an investment that makes the product better next time. Get users to their 'aha moment' fast, then build a reason to return that doesn't depend on your reminders. Habits, not features, are what keep users around.
