What information is available on the Metrics Dashboard?

The correct choice highlights a unique aspect of the Metrics Dashboard, focusing on user engagement with the app itself. Specifically, the number of minutes the app was open for gives event organizers insight into how actively attendees are interacting with the app during the event. This data is crucial for understanding user engagement levels, which can inform future app development and event planning efforts. Higher app usage time can indicate a more positive user experience and could correlate with overall event satisfaction.

The other options, while they may represent valuable metrics in their own right, do not focus on app engagement. Total registrations pertain to overall participation rather than specific app usage. The percentage of attendees who provided feedback relates to post-event evaluation, and the number of sessions attended indicates attendance behavior but not the engagement with the app itself. Thus, the chosen answer reflects the Metrics Dashboard's emphasis on quantifying app interaction, which is vital for assessing the effectiveness of the mobile event app in enhancing attendee experience.
