The Visits section allows you to keep track of who's been looking at your album. To access the Visits section, tap the "Recents" icon at the bottom of the screen. Family members who have joined your album will be displayed at the top of the screen. The times displayed below each family member's icon show when they last visited your album.
The Visits section will not display your own account, as the last time you accessed FamilyAlbum would always be "now." However, when other family members access the Visits section, they can see when you last logged in.
To learn how to disable the Visits section, please refer to Can I disable the Visits section?
