I saw an app once on a friend's device, i dont know what device or what the app was called, what the app did was show a dark green circle, like a radar display, in the middle of the circle was a bright green arrow, representing the person holding the phone, and an the circle it would show bright green dots representing wifi hotspots. next to each dot had the hotspot name, and the number of feet away from you the hotspot is. the idea was that you would be able to see the approximate location of a hotspot, along with the direction it was in, so that you knew where to go to get a stronger signal. if anyone knows an app like the one i described, let me know!
