PCAPdroid

PCAPdroid is a privacy-friendly open source app which can track, analyze and block the connections made by the other apps on the device.

It can also export a PCAP dump of the traffic, inspect HTTP requests, decrypt TLS traffic and much more.

PCAPdroid simulates a VPN in order to capture the network traffic without root. It does not use a remote VPN server, instead data is processed locally on the device.

Main features:

* Log and analyze the connections made by user and system apps

* Get a summary of how much data each app sent and received

* Low battery usage for continuous, all-day capture

* Extract hosts and IP addresses from DNS, TLS and HTTP

* Record the traffic to PCAP files with additional app metadata

* Send traffic via PCAP-over-IP for real-time analysis (e.g. on Wireshark)

* Decrypt the HTTPS/TLS traffic, extract the URLs and save the SSLKEYLOGFILE

* Inspect the HTTP requests/replies and export them to HAR

* Identify the country and ASN of the remote server via offline DB lookups

* On rooted devices, capture the traffic while other VPN apps are running
