User vs Session in Google Analytics

A visitor (user) who uses the e-paper 100 times on the same device should be counted as one user, but 100 sessions.

A user is thus a unique visitor per device. A user can be a returning visitor and thus a recurrent user (as long as the user can be traced back over several dates).

A session is a traceable use (i.e. a traceable viewing of a "screen" in the app (in the web app "screen" is called "page")) of the e-paper within a fixed activity, where a new session is started due to inactivity (usually 30 minutes per default), where there is no upper limit on how long an active session can last. It is thus an activity that the user performs during a specific date.

Whatever a user does in the app is always collected as part of a session, regardless of whether the user is reading in article or replica reading mode or just looking at other parts of the app (e.g. the home page or the archive).
