AP Grapher is a freeware program for Mac OS X which searches for and displays nearby wireless (AirPort/WiFi) access points along with information about their percent availability, maximum Signal strength, and last contact time. The grapher window allows you to graph multiple signal strength parameters for the base station you are currently Connected to and optionally display them in the dock icon. Many user configurable preferences allow you to customize its behavior including refresh rate and optional display in the dock icon or menu extra.
