Tried to turn on one item and it jumped to Shortcuts and then to another screen to install something else but as a popup - no information provided. Another screen wanted me to enable a bunch of settings and called it “Touch”. No idea what that is. Then checked info and saw prices in British pounds to purchase additional features. So as a cybersecurity expert, didn’t trust a single thing about this.
Unparalleled information

Those complaining about how this has to install - blame Apple, not the developer. I do Wi-Fi professionally and the amount of information it is able to gather is unbelievable. This is the very best app for deep Wi-Fi analysis on iOS!
Best iOS WiFi analyzer

Without needing extra hardware this is by far the best wifi analyzer out there, the setup takes a minute to do but it guides you the whole way and works great without having to break out a dedicated analyzer
Can’t get it to do anything.

First of all, there’s nothing easy about this app. I installed it and expected to be able to see my Wi-Fi final or at least some sort of UI. Instead I’m asked to press vol up + vol down + power. Which takes a screenshot? It’s supposed to generate a log of some sort but it’s not at all for me. Really had high hopes too
Developer Response
UPDATE: Please try the latest 5.1.0 release. We have taken your comments to improve things and with iOS 17, can now provide live Wi-Fi data.We are sorry it didn’t work out for you. Unfortunately there is no other way to get this info on Apple devices which is why you won’t find another iPhone or iPad app which can give you the information you want. nOversight is the first app to be able to do this at all. The method of pressing Vol Up + Vol Down + Power is the Apple way to capture a diagnostic log. We didn’t create it and have to live with it if we want any access to this kind of info at all. We recognise this can be tricky which is why the app is completely free up to a point so you can try it out without any commitment. There is another method using the device’s accessibility functions but this is also not a great user experience. Again it is an Apple defined process. Prompted by your review, we will write a guide for it. You contacted us via support and we responded within a few hours. We will use this channel to inform you of the other methods and learn if this is easier.
