WiFi Directory — You can never have too much Wi-Fi, which is what makes WiFi Directory (Wireless Hotspots Finder) as appealing to me as a medium-rare steak is to my dog Henry, who will eat anything other than dog food.

WifiTrak Works Like a Geiger Counter for Wi-Fi Networks
WifiTrak (Find FREE WiFi), from Bitrino, is the equivalent of a Geiger Counter for people who are looking for nearby Wi-Fi networks and devices.
WifiTrak is a simple tool that searches for Wi-Fi nets and tests each for accessibility, whether the Wi-Fi network is open or secure, type of security it employs, whether it's visible or hidden, signal strength and channel.
