0-Day or DAU or 0D is the first day someone opens the app. 1-Day is the 1st day after the initial day – so for example, your 3-Day Active User count will include everyone last opening your app on the 1st day they installed + the 3 days after that.
Which is the 1st day that someone uses the app? Print
