See every device on your Wi-Fi. Find printers, TVs and IoT gadgets with mDNS and SSDP, spot risky services, and export packet captures. Open source, no tracking.
mDNSShark is an open-source iPhone app that shows what is on your local network. It uses Multicast DNS (mDNS), DNS-SD, and SSDP to find printers, media servers, IoT gadgets, and other services on your Wi-Fi, with no setup.
WHAT YOU GET
- Device discovery: Bonjour/mDNS, SSDP, and subnet scans, with manufacturer lookups.
- Security assessment: flags risky exposed services and checks device manufacturers against CISA's Known Exploited Vulnerabilities catalog and the NVD.
- Packet capture: see which servers your phone talks to (DNS lookups, IP addresses, ports) 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.
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. 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.
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
mDNSShark is built by engineers who like transparent, lightweight tools, and it is open to anyone curious about local networks. Report bugs, suggest features, or contribute code in our public repository: https://github.com/Shapehaven-Innovations/mDNSShark

What's New in 1.9
Devices
- Device rows now update when a MAC address, manufacturer, or inferred OS arrives later in a scan.
- New OS hints for Espressif IoT devices, LG webOS TVs, and Amcrest cameras.
- Devices that advertise Apple Continuity services are now identified as Apple devices, with a generic Apple icon unless the model identifies an iPhone or iPad.
- Added discovery for three more Apple services.
Security
- The Findings count is now labelled "Findings" and shown in blue, so it is no longer confused with the number of vulnerable devices.
- Analysis recommendations count distinct devices, using the same rule as the "vulnerable" count in the header. Vendor advisories no longer inflate it.
- Exposed VNC and RDP are now rated Warning instead of Critical, and services advertised over Bonjour are now Informational.
- Fixed TLS bypass matching: listed domains are now recognized from DNS lookups, and look-alike domains no longer match.
- The Security tab footer is now a single Refresh button with one status line showing when threat data was last updated. Privacy and data source notes moved to Settings.
- TLS error banners now use plain language.
Certificates and capture
- Remove Certificate now asks for confirmation. Afterward, an alert explains that the iOS profile stays installed and has an Open Settings button. To finish, go to Settings > General > VPN & Device Management and remove the mDNSShark profile.
- New Delete Capture option.
- Exported pcap and metadata files now share a matching name.
- DNS queries and responses are labelled in the packet list.
Appearance
- The in-app theme switch is removed. The app now always follows your system Light or Dark setting.
