PacketCircle

Open a PCAP and watch conversations bloom into a living circle. Spot talkers, protocols, and TCP health at a glance — then drill into decode without leaving your phone.

PacketCircle turns packet captures into a clear picture of who is talking to whom.

Instead of scrolling endless packet lists, you see communication pairs as an interactive circle: endpoints on the rim, conversations as edges, colors by protocol or session quality. Ideal when you need to understand a capture quickly — on site, in a meeting, or reviewing a file someone sent you.

What you can do • Open PCAP and PCAPNG captures • Explore Top talkers on a circle, table, or gauges view • Filter by protocol and focus on the conversations that matter • Inspect session health, ports/services, and application hints • Jump into a Wireshark-style decode (packet list, protocol tree, hex) • Follow TCP streams and export a conversation as PCAP

Built for analysis, not noise PacketCircle is a native iOS app with a shared engine designed for conversation-centric troubleshooting — DNS, HTTP, TLS, SMB, and more when the payload is visible — without requiring Wireshark on your phone.

Open a capture. See the circle. Understand the network.

Made with love for the packet community.
