PCAP Viewer
pcap and VoIP network analyzer
Free · Designed for iPad. Not verified for macOS.
Open pcap and pcapng captures on iPad: detailed dissection, powerful filters, SIP calls and RTP streams.
PCAP Viewer turns your iPad into a network protocol analyzer. Open a pcap or pcapng file received by email, AirDrop or Files and explore it as on your desktop: a colorized packet list, a detail tree and a hex dump, all linked together.
Available in English and French.
