PROX (short for Proximity) is an app that uploads pictures taken on your phone to a central database. Anyone that was in close proximity to you (25 to 50 meters) when the picture was taken can view the photo for 24 hours from the time is was taken/uploaded. So, for anywhere you have been over the last 24 hours, you should be able to view photos that were taken by other PROX users while you were at that location.
