What about the apps at https://mashtips.com/best-iphone-wifi-tools-network-analyzer/
I have an iPhone 6 I can test with but will NOT pay for such as I have free excellent scanners on my droid.
I am looking for an App for iPhone or iPad that will do WIFI analysis. There are tons of apps that will do LAN scanning once you are attached to WIFI, or will manage your known APs with SSID and password. But there is NOTHING out there (that I can find) that can do this:
Scan all WIFI AP broadcasts in the area to identify all APs within reach, the channel and they are on, identify encryption level used, and show the signal strength to tell proximity to the AP device. And then show it all on a simple single-pane-of-glass signal strength meter graph graduated against the radio spectrum.
We routinely use this kind of app on Andriod phones to (1) scan for rogue APs in the network (2) Identify proper channel placement for a new AP in the radio environment. (3) determine the strongest AP to connect to in non-mesh WIFI environments.
Does anyone know of a similar app on IOS that can do this ONE SIMPLE THING??
