From the developer:
WiFinder helps you scan, graph, and GPS map WiFi networks.
Using advanced GPS technology, WiFinder scans and places all networks on a map. While walking or driving, WiFinder will automatically update the location of networks if it finds a position that will provide a better signal. Open networks are clearly marked with a green dot, and closed networks with a red dot.
