Sniffer Proxymon: Debug TCP Connections on Android
Sniffer Proxymon [ROOT] is an Android app by evbadroid that allows you to debug communication on open and secure TCP connections over IPv4. This utility and tool app works on the content level and is able to unpack the data. With Sniffer Proxymon, you can monitor the traffic of other apps on your device and inspect their communication with servers. However, to decrypt SSL/TLS, a special CA certificate must be installed on the debugged system.
The app's simple interface makes it easy to use, even for those who are not familiar with debugging. Sniffer Proxymon is a free app and can be downloaded from the Google Play Store.
