The Access Points tab shows many essential details. One feature we liked allows saving notes to individual SSIDs, which are then included in any data exports. The Frequency Usage tab displays channel visualizations for the 2. They do the job of showing channel usage including channel-bonding and signal strength, but it would be nice if they had a single view of the entire 5GHz band instead of dividing it into four different graphs.

For a free application, Homedale offers great exporting capabilities. It supports saving the network list as a CSV, logging networks from every scan useful if moving while scanning , and saving an image of each graph. Although the GUI is very simple, Homedale provides some advanced functionality. We were impressed with its exporting, logging and location-aware features.

The Best WiFi Analyser For Mac (12222)

A really cool extra feature in WiFi Scanner 1. Thanks for offering this to the community for free! Next up is the donationware iStumbler. This tool also includes not just the WiFi information around you, but also Bluetooth and Bonjour services nearby. A nice extra feature to be sure. I prefer the rev.
