What is WiFi Explorer?
WiFi Explorer is a tool to scan, find, and troubleshoot wireless networks. It can be used to quickly identify channel conflicts, overlapping and other factors (e.g. configuration issues) that may be affecting the connectivity and/or performance of your wireless network in homes, offices and other sites. It can also be used to find open, ad-hoc and even rogue access points. Additionally, it detects 802.11a/b/g/n/ac wireless networks and supports 2.4 and 5 GHz channel bands, as well as 20, 40, 80 and 160 MHz channels. It can also monitor signal strength of each network over time and export metrics (average, maximum signal strength, etc.) and network details to CSV file format.

Said about WiFi Explorer as an alternative
It's free and is a great alternative to iStumbler, MacStumbler, KisMac, etc. The free version shows the BSSID, Network Name, Vendor, Signal strength, Channel, Channel Width, Band, Mode, Generation, Max Rate, Security, and Scan. I would have kept using iStumbler but they decided to charge money for it. This is a great alternative!
WiFi Explorer has worked well for me in showing local WiFi networks. It has useful dual pane style listing found networks and showing graph(s) of their relative strength and possible overlap.Worth checking it out.
