Retention rate with a likely range
Type how many players started on a day and how many of them came back. You get the retention rate and a likely range, so you can see how much of a change could be chance.

How it works
Retention rate is the players who came back divided by the players who started.
The likely range is a 95% Wilson score interval. It always stays between 0% and 100%, and it gets wider when the cohort is small.
Keep in mind
- The range only covers chance. It can't tell you why retention changed.
- Compare cohorts that started on similar days. Weekends, events and ads bring different players.
