Read the shape before the number
Use the curve’s changing slope to locate where the product relationship weakens.
A retention percentage is a snapshot. The shape of the curve tells you how the relationship changes over time. Begin by tracing where the line falls quickly, where the decline slows, and whether it ever settles into a stable band.
A steep early drop points toward the path from first use to repeated value. A later drop suggests that the product delivered something initially but failed to remain useful when another opportunity appeared. The same final percentage can therefore hide two different product problems.
Do not choose a fix from the curve alone. Use its shape to form a narrower question. Then inspect the behavior and context around the interval where the slope changes.
If two products both retain 24 percent at week eight, but one loses most users in week one and the other declines steadily, the first team should inspect early value while the second should inspect the repeated use case.

A curve identifies where to investigate. It does not prove why people left.
