Network Analyzer is a free, easy-to-use network toolkit that turns your iPhone or iPad into a handy diagnostic instrument. Scan your network, discover every device connected to it, and troubleshoot connection problems in seconds - no technical background or extra hardware required. Built for curious home users and IT professionals alike, it packs a LAN device scanner, ping, traceroute, port scanner, DNS lookup, and whois into one clean, fast app. Try it for free, and upgrade to Network Analyzer Pro whenever you want advanced tools like traceroute visualization on the map, internet speed test, Wake on LAN, IP calculator, MAC address browser, and more. LAN scanner: - Fast and reliable detection of all network devices - IP addresses of all discovered devices - MAC addresses and vendor names of discovered devices - NetBIOS, mDNS (Bonjour), LLMNR, DNS, SNMP, and WS-Discovery name where available - Reachability (ping) test of discovered devices - IPv6 availability and discovered IPv6 addresses Ping & traceroute: - Round-trip delay including IP address and hostname for every network node - Country detection of the analyzed server - Support for both IPv4 and IPv6 Port scanner: - Scan common ports, custom port ranges, or the complete port range - Detection of closed, firewalled, and open ports - Description of the known open port services Whois: - Look up domains, IP addresses, and AS numbers - Support for both classic whois and the modern RDAP protocol DNS lookup: - Functionality similar to nslookup or dig - Query all record types at once or one specific type - Support for A, AAAA, CAA, CNAME, HINFO, LOC, MX, NAPTR, NS, PTR, SOA, SPF, SRV, SSHFP, TXT records Network information: - Default gateway, external IP (v4 and v6), DNS server, HTTP proxy - Wi-Fi network information such as SSID, BSSID, router vendor, security type, IP address (v4 and v6), and subnet mask - VPN, USB Ethernet, and personal hotspot connection details - Cell network information such as IP address and network type, with dual SIM support More: - Light and dark theme - Full IPv6 support everywhere - Detailed help - Regular updates

PCAP Analyzer opens and analyzes .pcap and .pcapng network captures right on your iPhone, iPad, and Mac, with no desktop required. Troubleshoot a flaky connection, investigate a security incident, or learn how networks really work, with a fast, deep, and clear packet analyzer in your pocket. Open captures created by tcpdump, tshark, and any standard pcap or pcapng tool, and read the wire like a page. DEEP PROTOCOL DECODING Every frame is dissected down to the field: Ethernet and VLAN, IPv4, IPv6, TCP, UDP, ICMP, ICMPv6, IGMP, ARP, DNS, mDNS, LLMNR, DHCP, HTTP, HTTP/2, TLS, DTLS, QUIC, SMB2, SNMP, NTP, RADIUS, TFTP, MQTT, SCTP, GRE, ESP, and NetFlow/IPFIX. A clean, tappable detail tree and a full hex view show every byte. TLS FINGERPRINTING, JA3 AND JA4 PCAP Analyzer computes JA3 and JA4 client fingerprints natively, and even decrypts QUIC Initial packets to recover the SNI and fingerprints, analysis that usually needs desktop plugins. FIND THE PROBLEM FAST • Color coded packets, so retransmissions, resets, errors, and stalls stand out • Expert diagnostics: TCP retransmissions, duplicate ACKs, zero window stalls, connection resets, HTTP errors, and DNS failures • Threat detection: port and host scans, suspicious C2 and backdoor ports, possible DNS tunneling, and cleartext credentials POWERFUL DISPLAY FILTER A real, field aware filter language with autocomplete and saved filters: tcp.port == 443, tls.sni contains "example", tcp.analysis.zero_window, dns or http. Tap any field in a packet to filter by it instantly. STATISTICS AND VISUALS Conversations, Endpoints, Protocol Hierarchy, a network topology map, an I/O graph, Follow Stream with a TCP sequence and time graph, and automatic name resolution, so you see hostnames instead of raw IP addresses. ON-DEVICE AI On supported iPhones with Apple Intelligence, an on device model summarizes a capture in plain language and turns plain English requests into filters, like "show failed connections". It runs entirely on your device, and your capture never leaves your phone. BUILT FOR BIG CAPTURES A native streaming engine opens very large captures without running out of memory, files that crash other mobile viewers. PRIVATE BY DESIGN Everything happens on your device. PCAP Analyzer reads saved files only, captures no live traffic, needs no special permissions, and never uploads your data.
