Explain to us what is the hook model. The hooked model is a design experience to connect your user's problem with your product with enough frequency to form a habit where the business lives or dies based on how good it can reduce customer churn by forming a long term habit. The way we know a habit is formed is that you don't need those external triggers at all. 90% of the time that people check their phone, it's not because of a ping, ding or ring, it's because of what's called an internal trigger. Boredom, loneliness, fatigue, anxiety. That is when we know a habit is when the user doesn't need any kind of spammy messaging or notifications. They use the product on their own with little or no conscious thought, purely out of habit.
