mDNSShark vs PingKit

mDNSShark is an open-source network scanner for iPhone, built for privacy-minded engineers and anyone curious about what is on their Wi-Fi. It listens to Multicast DNS (mDNS), DNS-SD (Bonjour) and SSDP/UPnP to find printers, cameras, media servers, smart home gear and other services on your local network, with no setup and no account. FOR CURIOUS MINDS Ever wondered what your TV, thermostat or camera is saying on your network? mDNSShark shows you: what a device announces about itself, which ports answer, and what your phone talks to. Built by engineers for the curious minded and explorers, with literal values and nothing hidden. WHAT YOU GET - Device discovery: Bonjour/mDNS, SSDP/UPnP, an ARP table read and a light sweep of your own subnet, with MAC vendor lookup. A long list of Bonjour service types is browsed, including cameras, Matter, Thread, appliances and 3D printers. - See what a device says about itself: TXT records are listed exactly as received, and vendors come from the device's own claim or its MAC. - Topology: a map of how devices connect, centered on your gateway, with devices on other networks shown apart. A Networks sheet lists this phone's networks, gateways and off-network devices. - Security assessment: flags risky exposed services such as Telnet, FTP, SMB and RTSP, and checks device manufacturers against CISA's Known Exploited Vulnerabilities catalog and the NVD. Only ports confirmed by a real connection are listed as open. - Probe this device: on request, and behind a confirmation, send the standard probes to a single address on another network. Devices that were never probed say Not probed. - Home Screen and Lock Screen widgets: Devices Online, Scan Now and Security at a Glance. On iOS 26 and later, Scan Now starts a scan right from the widget. - Packet capture: see which servers your phone talks to (DNS lookups, IP addresses, ports), capture mDNS traffic, and export to pcap for Wireshark. - TLS Inspection (optional subscription): decrypt and read your own device's HTTPS traffic using a certificate you install and trust, with a bypass list for apps you want left alone. PRIVACY Scans and analysis run on your phone. Your device list and scan results are never uploaded; only vendor names are sent to the NVD when you tap Refresh CISA Data. Widgets read a snapshot stored on your device. There is no telemetry, no analytics, and no trackers. Two things leave your device, and both are visible to you: while Packet Capture is on, DNS lookups go to the resolver you choose (Google Public DNS by default), and the Refresh CISA Data button you tap yourself downloads CISA's public catalog and asks the NVD about device vendors seen on your network. Discovery needs only local network access; Packet Capture also asks you to allow a VPN configuration. SUPPORT ACTIVE DEVELOPMENT The optional TLS Inspection subscription helps fund active development of mDNSShark: new features, fixes and upkeep. SUBSCRIPTION TLS Inspection Monthly is an auto-renewing monthly subscription. The price and any free trial are shown in the app before you subscribe.

Is it your Wi-Fi, or is it your ISP? PingKit Guardian finds out, with a 1-week free trial. It tests your iPhone, your network, your router and the internet beyond it, then tells you in plain words where the problem is and what to do about it. While you are away, Guardian keeps watch: 10 sites or TCP ports checked every 5 minutes, with an alert when one goes down or recovers. The tools are free: 19 professional-grade network tools, no subscription needed. Devices on your network are found automatically and named from what they announce.
