Our Daylite App Web&Map offers you the possibility to display your contacts on a map. The following video shows you what the numbers on the card and the color of the pins mean.
The prerequisite for this is that at least macOS 10.11 (El Capitan) is installed.
The numbers on your map in Web&Map indicate how many contacts are clustered at one location. Zoom in to get a detailed view. The color of the pin then shows the Daylite category of the contact.
