Why users come back — designing the second session, building habit loops, measuring stickiness honestly, and the behavioural patterns behind long-term engagement.
View All TagsA user's second session is the highest-leverage session in the entire user lifecycle, and almost no product is designed for it.
Designs are written for the first session — the activation flow, the empty states, the welcome modal. Designs are written for the steady state — the populated dashboard, the established power-user surface. The second session sits between these two, and gets neither attention nor a name.
"Stickiness" is the most-used word in product retention talks and the least-defined. Pinned to a specific number, it's DAU/MAU — daily active users divided by monthly active users. As a piece of language, it's stretched to cover everything from "users come back" to "users like the product" to "the product has a moat."
The metric and the word have come apart. The metric is fine; the way it's interpreted has gotten loose.
