Great app but......

The app has plenty of options, but for a novice, it is to advanced. Is there anyway for a refund?

The most I’ve ever paid for an app

Worth every penny. Developers, pentesters, and people who just wanna see what apps are doing in the background on your device, this app is perfect. Watch Facebook constantly do stuff you told it not to, watch apps monitor your location, see shady telemetry performed in real-time!

I don’t know what to make of half of what I see in the sessions recorded by this app, but still for some reason I am infatuated with all the random network data this app can see. Its so cool knowing what apps are doing when you run them.
