mDNSShark vs NetProbeX

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. Payment is charged to your Apple Account at confirmation of purchase, or when a free trial ends. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel any time in Settings > Apple Account > Subscriptions. Discovery, scans, and the Security tab are free. OPEN SOURCE AND YOUR VOICE mDNSShark is built in the open and your ideas shape it. Found a bug or want a feature? Open an issue and tell us.

NetProbeX shows you what's actually on your network — not just that a device exists, but what it's running and what it's exposing. WHY NETPROBEX Most network scanners tell you "a device is here" and stop. NetProbeX goes further: tap any open port and see the exact raw data the service sends back, in hex and ASCII, just like a professional network tool. No other consumer scanner shows you this. Everything runs on your device. There's no account to create, no cloud backend, and nothing about your network is ever sent anywhere except the one optional, manual public-IP check you can trigger yourself. WHAT YOU CAN DO • Discover every device on your Wi-Fi — routers, phones, laptops, printers, smart speakers, cameras — with real names via mDNS/Bonjour, not just IP addresses. • Raw Response Inspector — tap an open port and see the exact bytes the service returns. Copy it, export it, or send your own custom probe. • Hidden Camera Finder — scan for exposed RTSP/DVR camera ports, the kind hidden cameras and unsecured IP cameras commonly leave open. • Router Vulnerability Check — a read-only look at whether your router has UPnP, NAT-PMP, or Telnet left open, the three most common home-router misconfigurations. • Real diagnostics — actual ICMP ping and traceroute (not an approximation), DNS lookup, and an internet speed test. • Wake on LAN — save a device's MAC once and wake a sleeping PC or NAS on demand. • Rename, label, and hide devices — keep notes on a busy network so you can identify the culprit fast if something causes a slowdown or an IP conflict. • Save scans and revisit them anytime. HONEST ABOUT WHAT IT CAN'T DO Apple restricts what any app — including NetProbeX — can see about other devices' real hardware (MAC) addresses, as a privacy protection. NetProbeX respects this rather than trying to work around it: device identification relies on network behavior, hostnames, and mDNS names, which is what makes NetProbeX reliable where other scanners overpromise. Built for anyone who's ever wondered "what is that device on my network?" — from home users curious about their smart devices to IT-minded people managing a busy office Wi-Fi.
