PCAP Analyzer · File Reader vs Open Adaptive Switch

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.

Open Adaptive Switch is the companion app for a do-it-yourself Bluetooth accessibility switch. It lets a caregiver set up and manage the switch from an iPhone or iPad, with no cables and no computer. Please note: this app requires the matching hardware. Open Adaptive Switch is an open-source switch that you build yourself from inexpensive parts (a Seeed XIAO nRF52840 board, a button, and a small battery) for roughly ~$15. Full build instructions and firmware are free at github.com/mikavj/open-adaptive-switch. Without the hardware, the app has nothing to connect to. The switch works with iOS Switch Control, so a single button press can tap the screen, run a recipe, or drive the scanner, giving people with limited mobility an affordable way to use an iPad or iPhone. With the app you can: Choose the key the button sends, from a full list including the F13-F24 keys that pair cleanly with Switch Control, plus letters, numbers, and common keys, with modifiers. Switch between single-key, tap-or-hold, and short/medium/long press modes, so one button can trigger up to three actions. Set how long the switch waits before it sleeps to save battery. Rename the switch and pick a color in the app to match the button you built. See the battery level and charging state, including in the list of nearby switches before you connect. Install firmware updates over Bluetooth, choose any released version, or roll back if needed. The app collects no personal data. It uses Bluetooth to reach your switch and contacts GitHub only to check for firmware updates, which you can turn off. Open Adaptive Switch is free and open-source, built to make assistive technology affordable for families, classrooms, and anyone who needs it.
