Snapchat's Snap Map shows you where your friends are and what they are doing
Snapchat has a new feature called Snap Map that will show you on a map where your friends are, and what they are doing. To get to the map, you simply go to the camera tab and pinch to zoom out to view it. Tap on your friends if you want to start a chat, or to see when their location was updated last. If your friends have their Bitmoji account linked, you'll be able to see if they are driving, walking or doing other things.
With Snap Map you can view Snaps of events taking place all over the world. A Snap must be submitted to Our Story for it to appear. And you can search for friends by using the search tool and writing in the name of the person you're looking for.
You might not want everyone in the world (especially your boss) to follow you on Snap Map. To change who can see you on the map, tap on the settings icon on the upper right side of the Map screen. Options include Ghost Mode which prevents others from seeing your location on the map. My Friends allows all of your pals, including ones just made, to see your location on the map. Lastly, there is Select Friends. The latter allows you to pick which friends will be able to see you on the Snap Map.
