“the hook cycle that he introduces in the book is a framework that I'm using in all my products now that I know its power to make people retain you will create high retention products with happy customers that use it for their own benefit if you implement it well”

Engineer the hook cycle for ethical retention

Map Nir Eyal's four-step loop (trigger → action → variable reward → investment) onto your onboarding and lifecycle flows. Without an investment step, even great products stay one-night-stand tools. Tie the reward to outcomes the user is genuinely proud of — high retention then becomes a side effect of real value, not manipulation. (Nir Eyal, Hooked.)
