Is there an app to mark places on a map?
Mapstr lets you keep track of all your favorite places around the world, tag them, and find them on your very own map!
Can you mark on Google Maps?
Once you are on the map creation page, click the marker icon to add a marker to the page. Find a place on the map you want to add a marker and click on that location on the map. This will place a marker on the map and bring up a box where you can add a name, description, and other attributes to the marker.
