A gathering indicates that a group of your friends, two or more, are at the same location🔥.
The number of people at the gathering displays in the bottom right corner of the icon. Clicking on the map pin will zoom-in on the map, showing everyone present.
It's important to note that a gathering cannot occur if everyone present is at their home, school, or work. For example, if three siblings using Zenly are at home, a gathering will not be displayed. However, if a friend using Zenly comes over to visit, a gathering will be displayed for everyone present.
