Network Scanner Toolkit vs SigScan

See every device on your WiFi. Free — no ads, no subscription. Network Scanner Toolkit finds everything on your network in seconds: name, IP, MAC address and manufacturer (iOS 27+) — even devices that hide from ping. Devices tell you what they are: Apple TV, HomePod, Chromecast, printers, HomeKit and Matter gear, Sonos, Fire TV, Windows PCs, NAS boxes and more. Capability tags show which are pingable, run a web interface, speak Bonjour, UPnP or Matter, or are your gateway. Filter by Web UI, SSH, file shares, printers, TVs, smart home or cameras. Tap a device to ping it, open its admin page, connect over SSH, VNC or SMB, rename or favorite it. New devices are flagged automatically. Made for big screens. On iPad and the iPhone Duo the scanner becomes three columns — past scans, device list and full details side by side — and the tools spread into two panes. Stand the Duo up like a laptop and every tool splits across the hinge: graph, map or results on top, controls below. Fold, unfold or rotate and nothing is lost. A full network toolbox — free: • LAN Scanner — fast sweep with naming over Bonjour, NetBIOS, WS-Discovery and SNMP; models and manufacturers, custom names & icons, new-device badges, filters, quick-connect. Scans Wi-Fi, Personal Hotspot or wired, and keeps going after you leave the app (iOS 26+). • Subnet Tools — IPv4 and IPv6. Type any address with a prefix, netmask or wildcard and get the whole answer on one card: network, broadcast, host range, counts, type with its RFC, binary with host bits highlighted. Then explore: child subnets on a visual map, VLSM planner, overlap checker, supernet, membership test, range-to-CIDR, config lines, IPv6 forms, netmask table. Siri Shortcut included. • Port Scanner — presets, custom ranges, or all 65,535 ports • Traceroute — every hop geolocated on a live map with latency charts • Ping — live graph, configurable payload size and interval • DNS Lookup — A, AAAA, MX, TXT, CNAME, NS, SOA, PTR, SRV, HTTPS & SVCB records, custom resolvers, DNSSEC check • Whois — modern RDAP lookups for domains, IPs and AS numbers, with classic WHOIS referral chasing as the fallback • Bonjour Monitor — watch services appear and disappear live • Siri & Shortcuts — scan the network, find or ping a device, check if it's online, look up DNS, check your router, open a device, calculate a subnet. • Port Peek — tap any open port and read what the service announces: SSH version, web headers, mail and FTP greetings, telnet banners. • Network Info — IP, router, DNS, IPv6, data usage, SSID, and a Router card that names your router, shows its WAN address and tells you whether you're Direct, behind Double NAT or on Carrier-grade NAT, in plain English • History — every scan and test saved automatically Toolkit Pro — one purchase, yours forever: • Find Cameras — sweep for security cameras using RTSP, ONVIF, camera web interfaces hree-tier confidence ratings. Know what's watching on any WiFi you join. • MAC Explorer — paste any MAC in any format and see its vendor, IEEE registry block, address bits, reserved uses, every notation and the IPv6 address it implies. • Speed Test — live download and upload graphs in Mbps and MB/s with a bufferbloat grade • Security Audit — find exposed or insecure services on every device and ports your rrnet, with a fix for each finding and an A–F grade • Find Trackers — spot Tile, Samsung SmartTag and Google Find My Device tags traveling with you • Cert Check — any website or device's ssl certificate: trusted or self-signed, days left, issuer, names, chain, key, TLS version, fingerprint • Bluetooth Scanner — see nearby Bluetooth LE devices with signal strength, maker and type; locate one with the hot/cold Find meter or the radar view • Wake-on-LAN — wake your PC or NAS from the couch • Export & share — CSV and PDF reports of any scan or test; Whois and DNS results as text, JSON or CSV • Themes Private by design. No account, no analytics, no tracking.

The air around you is full of invisible signals. SigScan makes them visible. Turn once and see which way everything is. The radar places every nearby Bluetooth device around you by distance, on a compass that turns with you. Turn in a circle and SigScan finds each device's direction from how its signal rises and falls. Point your phone around a room and every nearby Bluetooth device appears as a floating bubble in augmented reality, anchored in real space. Devices behind walls fade; off-screen devices show as compass arrows. ON-DEVICE INTELLIGENCE Every identification SigScan makes happens on your iPhone, offline, in milliseconds. No scan data is uploaded to be analysed. - Identity engine: each broadcast is broken into signals (company, services, product codes, name) and weighed against an on-device index of 22,000+ manufacturers. The strongest claim wins; runners-up show what else a device could be. - Confidence and evidence: every result carries a confidence score and the exact evidence it was built from. - Device classes: phones, computers, wearables, audio, trackers, TVs, cameras, smart home gear and appliances are told apart from the broadcast itself. Brands that make many kinds of product are never guessed. - Anomaly detection: devices that move with you, unnamed high-power devices and known trackers are surfaced automatically. - Live sensor decoding: temperature, humidity, battery, motion and contact state are read straight from the air. WHAT SIGSCAN SEES - Bluetooth devices: manufacturer, product, signal strength and estimated distance - NFC tags: hold your phone against a tag to decode what is on it - Your network: details of the WiFi network you are joined to, local devices, services and discovery traffic - HomeKit accessories: every one by room, with model, serial and firmware version - Cellular: your network type and radio technology EVERY MANUFACTURER, NOT A SHORTLIST SigScan carries the complete Bluetooth industry registry and the full IEEE hardware registry: more than 22,000 manufacturers and 44,000 identifiers, held entirely on your device. Where a manufacturer publishes its advertising format, SigScan names the exact product: SwitchBot and Xiaomi devices are identified down to the model. THE CHIP AND THE BRAND ARE DIFFERENT THINGS Most devices use somebody else's radio, so scanners often report a sensor as an Espressif or Nordic device. SigScan reports chip maker and brand separately. FIND UNKNOWN TRACKERS SigScan flags known tracker models and hardware from vendors on the FCC Covered List or restricted under Section 889, including their subsidiaries. YOUR SCAN HISTORY, MAPPED Every scan is saved on your device with where it happened. Review sessions on a map and export as CSV. ASK QUESTIONS IN PLAIN ENGLISH An optional assistant answers questions about your scan results, such as what the strongest unknown device near you is or whether anything new appeared in the last ten minutes. It is the one feature that uses the internet: it sends a short summary of the devices SigScan has already identified, never your location and never any device identifier. SHARE, WIDGET AND YOUR WAY Share any device with friends through Messages, AirDrop or Mail. Add the home screen widget to see what your last scan found. Choose which screens sit in your tab bar, and pick Light, Dark or System appearance. EVERYTHING EXPLAINED Tap the information icon beside any reading for a plain explanation, or open the glossary. PRIVATE BY DESIGN Your scan data and locations never leave your device. No accounts, no ads, no tracking. REQUIREMENTS - iPhone with iOS 17 or later - AR features work best on LiDAR-equipped iPhones (iPhone 12 Pro and later Pro models) - Bluetooth, camera and location permissions for full functionality SigScan is a tool for understanding your own wireless surroundings and checking your own devices and spaces.
