I am trying to monitor the Google Analytics request on an iPhone application and for some reason I don't see any of GA the requests. However I can see and uniquely identify the traffic on the google analytics interface.
I have tried using several technics including using Fiddler/Charles as a proxy and overlap the computer ip. While I can see many http request using this technic, I don't see any request that are related to Google Analytics.

What can be done to capture these requests?

Note:
As far as I know, there is no iOS app to capture HTTP request on the actual device.
