# User Retention
> Understand how many users return after their first activity date using Twinalyze User Retention.
User Retention helps you understand how many users come back after their first activity date.
The retention view groups users by date and shows how many of them return on Day 0, Day 1, Day 2, and later days.
***
## Common use cases
Use retention to understand whether users return after their first activity.
If Day 1 or Day 2 is low, users may not be finding enough value after first use.
Strong retention means users are repeatedly engaging with your product.
