PhotSpot

PhotSpot is an android application.
PhotSpot will let you easily find out the popular spot at location of your choice.
It will retrieve public geotagged contents on the map screen and show them in clustered balloons.
the each number on the balloon shows the number of contents within the cluster, so that
the more the number it has, the more people take photos around that area.
