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.
Sometimes you need to have SSL pinning enabled and still check. You could include this and run the prod build which is pretty handy.
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.
