KozBon turns your local network into something you can actually understand. Open it and every mDNS / DNS-SD service in range appears in one organized list — media receivers, smart-home accessories, printers, file shares, Matter devices, Thread border routers, web servers, SSH endpoints, and dozens more. DISCOVER • Live, continuously-refreshing scan of every service advertised on your local network • 158 service types recognized out of the box, grouped into navigable categories • Tap any service to see its IP addresses, port, host name, TXT records, and protocol details • The list organizes itself into sections — one per device, or one per service type with a short description of the type when you sort by name • Filter and sort by name, category, or transport layer, and search across everything the scan has found BROADCAST • Publish your own service from your device in a few taps • Pick from the built-in library or define a custom type with your own TXT records • Watch it appear on neighboring devices the same instant ASK • A built-in assistant explains any service, or answers questions about your network in plain language • On-device Apple Intelligence by default — no cloud trip, no account, no servers • Or bring your own key for Anthropic Claude or Google Gemini when you want a bigger model • Each provider's model picker loads the models your key can actually use, so new ones appear without waiting for an app update • The Chat tab takes on the colours of whichever assistant you've selected • Swap assistants any time in Settings SIRI AND SHORTCUTS • "Scan for services" and "List discovered services" work from Siri, the Shortcuts app, and Spotlight • Spoken phrases are localized in all eight supported languages DESIGNED FOR EVERY SCREEN • Native SwiftUI on iPhone, iPad, Mac, and Apple Vision Pro — one app, built for each • Landscape and wide layouts, including the iPhone's inner display when unfolded, where the list and detail pane open side by side • Context menus for copying names, full type strings, IP addresses, and TXT records • A slow ambient colour wash behind every tab, with a switch in Settings to turn it off • Light, dark, and Increase Contrast appearances all native • Full keyboard navigation, VoiceOver labels on every control, and Dynamic Type throughout PRIVACY • Apple Intelligence runs entirely on device — your network details never leave it • Cloud assistant API keys live in the Keychain, locked to this device and never synced to iCloud • Requests are sent with storage turned off where the provider supports it, so no copy of your conversation is kept • No accounts, no telemetry, no servers of our own — KozBon is just an app Localized in English, Spanish, French, German, Japanese, Simplified Chinese, Arabic, and Hebrew, with full right-to-left layout support.

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.
