What it does when it runs

Diagnoses user retention using cohort data. Classifies the retention curve shape, identifies the churn type, matches the right intervention to the right problem, and points to the next experiment. Use when retention is below benchmark, when you have a retention rate but don't know why users are leaving, or when you've just shipped a major change and want to confirm it moved the needle.
