Escort has a new app available for smartphones to work in conjunction with their laser/radar detectors to post to a map any "hits" you recieve while driving. Anyone else can see them for 90 min. Kinda helpful to know about radar traps before you get to them. 25 mile radius for alerts and red light camera locations as well.
