Abstract: Systems and techniques to monitor performance of a single user session of an application installed in a client device are described. The application may transmit a request for data to a first server, and receive a response from the first server, the response including the requested data. The application may transmit, to a second server, (i) a transmit time at which the request is transmitted, and (ii) a receive time at which the response is received. The second server may facilitate displaying, on a computing device, the transmit time and the receive time. A developer may view such display to analyze the performance of the application during a single user session.
