tPacketCapture is a packet capturing app developed by SeriousDroid for Android devices. It is a free utility and tool available on the Google Play Store. The app captures packets without requiring any root permissions and uses the VpnService provided by the Android operating system. The captured data is stored in the external storage in PCAP file format. For detailed analysis, users can transfer the file to their PC and use software that handles PCAP format like Wireshark.

The app comes in two versions, tPacketCapture and tPacketCapture Pro. The Pro version includes an application filtering feature that captures only a specific application's communication. However, the free version is still a powerful tool for capturing packets without root permissions and analyzing them on a PC.
