WiFi Scout was developed by Devin Wong. This is a free app with no ads, and certainly the simplest app we reviewed. When you open WiFi Scout, you’re met with only two tabs: 2.4GHz and 5GHz. Both have a channel usage graph, showing the signal strength of each SSID. Below the graph, is the network list for that particular frequency band. Although the SSID, channel, signal, and state (active/inactive) are the only details shown by default, you can add the following: band, MAC address, encryption, authentication, physical kind (wireless standard), beacon interval, Wi-Fi direct support, and uptime.
