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.

AP Grapher is intended to help you find the best wireless access point to connect to and optimally position your base station and or computer to achieve the best possible signal strength. Note that the stumbler is not capable of finding intentionally hidden networks - it will only locate networks broadcasting their SSID (same as the default Airport menu on your Mac).

Features:

Grapher:
• Graphs up to five connection statistics at a time: signal, noise, SNR, transmit rate, and comm quality.
• Customizable colors and refresh rate.
• Ability to “mark” the graph at specific times.
• Optional history graph in dock icon.
• Optional menu extra to display connection quality and or speak it aloud.
• Adjustable history length - record only a few samples, or keep it going for an extended period of time as you walk around.

Scanner (Stumbler):
• Customizable colors and refresh rate.
• Keeps track of best signal strength.
• Calculates the percentage of time each access point is visible.
• Records the last contact time for each access point.
• Saves information about access points between launches.
• Options to hide secured and or inactive base stations.
• Option to speak newly discovered access point names.
• Export as CSV (comma separated values.)

Requirements:
OS X 10.4-10.5
