PCAP Analyzer brings powerful packet capture analysis to your iPhone. Open and analyze .pcap and .pcapng files directly on your device - no desktop computer, cloud upload, or external server required. Whether you’re a network engineer, developer, security professional, student, or simply troubleshooting a network issue, PCAP Analyzer gives you the essential tools to understand what’s happening inside a packet capture wherever you are. PACKET ANALYSIS Browse packets with clear protocol, source, destination, ports, timestamps, size, and packet details. Quickly filter traffic by protocols such as TCP, UDP, DNS, HTTP, TLS, ICMP, and many more. Use display filters to narrow down large captures and focus on the traffic that matters. PROTOCOL DISSECTION Inspect packets layer by layer - from Ethernet and IP to transport and application protocols. PCAP Analyzer supports dozens of protocols across multiple protocol groups, making it useful for analyzing everything from common Internet traffic to specialized network communications. FLOW ANALYSIS Turn thousands of individual packets into meaningful conversations. Explore TCP and UDP flows, see communicating endpoints, packet counts, transferred bytes, and traffic direction at a glance. CAPTURE STATISTICS Understand the overall behavior of your capture through visual statistics, including: • Total packets and bytes • Capture duration • Packets per second • Packets over time • Protocol hierarchy • Top talkers • Traffic direction RAW HEX VIEW Need to go deeper? Inspect the raw bytes of every packet with the built-in hexadecimal viewer. Switch between decoded packet details and raw packet data whenever you need byte-level analysis. BUILT FOR MOBILE PCAP Analyzer is designed specifically for phones - not simply a desktop interface squeezed onto a smaller screen. Open capture files from your device and investigate network traffic wherever you happen to be. Perfect for quick troubleshooting when you’re away from your workstation. PRIVATE BY DESIGN Your packet captures may contain sensitive network information. That’s why PCAP Analyzer processes capture files directly on your device. Your capture data does not need to be uploaded to a cloud analysis service just to inspect it. USE PCAP ANALYZER FOR • Network troubleshooting • Packet inspection • Protocol debugging • Application development • API troubleshooting • IoT debugging • Telecom protocol analysis • Network security investigation • Learning networking and protocols • Inspecting captures while away from your computer YOUR PACKET ANALYZER, IN YOUR POCKET Wireshark is invaluable when you’re sitting at a workstation. But sometimes the capture you need to inspect arrives when you’re nowhere near one. PCAP Analyzer gives you a fast, convenient way to open a capture, inspect packets, understand conversations, and identify what’s happening - directly from your iPhone. Open the capture. Follow the packets. Find the answer.
