Great app but......

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

Life saver for api devs

No more trying take to the word of the app team on what its cramming down your pipeline. Why try to catch it in the logs, when you can catch it before it leaves the app? Yeah they said they removed that dead ask but then how come it’s still sending my ssn number overseas?! Yeah get that crap in a .har so I can replay it in my browser. 5 stars.

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!
