NetProbe: LAN Scanner

Scan your Wi-Fi, map every device, and run real network diagnostics — ping, traceroute, port scan, DNS, WHOIS, TLS — all on your iPhone or iPad.

NetProbe turns your iPhone or iPad into a serious network diagnostics toolkit — the kind of thing IT pros keep on their laptop, now in your pocket.

DISCOVER YOUR NETWORK Scan your Wi-Fi to find every device connected to it — routers, laptops, phones, smart TVs, printers, and smart home gear. NetProbe identifies device vendors, MAC addresses, and open ports using standard, sandbox-safe techniques (ARP, mDNS/Bonjour, SSDP).

SEE IT MAPPED OUT An interactive network topology map shows how every device connects, with search, filtering, and live status — so you can actually see your network instead of guessing at it.

KNOW WHAT'S EXPOSED A plain-English health score flags risky open ports, weak TLS certificates, and other signals before someone else finds them — turning a scan into an actual security checkup.

A COMPLETE TOOLKIT • Ping — check connectivity to any host • Traceroute — trace the route to a host, hop by hop • Port Scan — scan common or custom TCP ports • DNS Lookup — A, MX, TXT, CNAME, SRV records • WHOIS Lookup — domain and IP registration info • ASN Lookup — find who announces an IP address • Subnet Calculator — CIDR ranges at a glance • TLS Certificate Inspector — check expiry, chain, and strength • HTTP Header Inspector — see exactly what a server returns • Website Security Check — headers, HSTS, CSP, and TLS in one pass • Wake-on-LAN — wake a sleeping device remotely • LAN Info — your IP, subnet, router, and Wi-Fi details

SAVE AND COMPARE Every scan is saved to history automatically, so you can compare two scans and see exactly what changed on your network — a new device, a port that opened, a device that disappeared.

WIDGET & SHORTCUTS Add the NetProbe widget to your Home Screen for an at-a-glance network summary, and use Siri Shortcuts to kick off a ping or quick scan hands-free.

PRIVATE BY DESIGN Everything runs on your device and your local network. Nothing is uploaded or shared unless you explicitly export or send a report yourself. There's no account, no ads, and no tracking.

NetProbe is for home users who want to understand their network, and for professionals who want real diagnostics without opening a laptop.
