Is it possible to modify the data received by a mobile device, using an app on the Mac or PC?

Question

I used Charles Proxy before, which can modify the data received by a browser, so it is really convenient that we can test our bug fixes without modifying the production server, either for the webpage content or for the AJAX data.

Is it possible to do something similar for a mobile phone app, either for iPhone and Android phones? I can let the Mac (or probably a PC too) act as a Wifi station (access point) and let the mobile phone connect to it, and is there an app that can act like Charles Proxy (perhaps Fiddler?) that can examine and modify data?

@nopole If you are using Charles, I suppose you can use Breakpoint feature to intercept and edit HTTP requests/responses coming from/to your mobile devices. It works for both browsers and mobile devices. Or else you can try using Proxyman . It's a native macOS app and quite similar to Charles/ Fiddler. You can read an example of how to use the Breakpoint to manipulate data here . Hope it helps! :)
