Can I identify the exact date that a detected activity for an App took place?

Setyl only ascertains the specific month that a Person logged into an App.

The "Last Activity" date is the month that there was last detected sharing between Setyl and the source of the detection. At times, the connection may automatically renew itself.

In Setyl, you can find the "Last Activity" date within Detected Activities of the App > "Last Activity" column.
