Why would you do it on the device itself where you can't easily work with the response (tweaking parameters in curl,..)? I always use Charles Proxy and it's great.

does it have any use cases that are not covered by https://www.charlesproxy.com/ios/?

It should really say "HTTP[S]" calls, or "Web" calls or somesuch - when I saw "Network" I hoped it would be a debugger for, say, UDP packets and TCP traffic. It's not.

Amazing. It is Objective c compatible?

seems like a copy of https://github.com/kasketis/netfox

any different to netfox?
