NetMonitor: WiFi Scanner & Map

10 professional network tools. Zero cloud. Zero ads. Zero subscriptions. Everything runs locally on your device.
NetMonitor is a complete network diagnostics toolkit for iOS. Scan your network, discover every connected device, trace routes across the globe, and diagnose issues in seconds — all without creating an account or sending a single byte to the cloud.
WHO IT'S FOR
* Network admins — Monitor infrastructure and catch rogue devices
* Developers — Debug connectivity, inspect DNS, scan ports
* Homelab enthusiasts — Map your entire network and track every device
* Anyone on WiFi — Understand what's connected and how your network is performing
NETWORK DASHBOARD
A single screen with everything that matters: live health score combining latency, packet loss, and DNS responsiveness. Gateway status, public IP, ISP details, jitter spectrum, and a live event feed.
DEVICE DISCOVERY
Find devices other apps miss. NetMonitor's multi-phase engine uses ARP, Bonjour, TCP probes, SSDP, ICMP, and reverse DNS to build a complete picture of your network. See IP addresses, MAC addresses, vendor names, open ports, running services, and connection history for every device.
NETWORK MAP
Visual topology of your entire network with real-time status and response times. Tap any device for details, port scans, and quick actions.
10 BUILT-IN TOOLS
* Ping — ICMP with TCP fallback and live latency graphs
* Traceroute — Hop-by-hop path analysis
* GeoTrace — Visual traceroute plotted on a world map
* World Ping — Reachability from 20+ global nodes simultaneously
* Port Scanner — TCP scanning with preset and custom ranges
* DNS Lookup — A, AAAA, MX, NS, TXT, and CNAME records
* Speed Test — Download/upload throughput with jitter and history
* WHOIS — Domain registration and ownership lookup
* Bonjour Browser — Discover mDNS services on your network
GEOTRACE
See the physical path your traffic takes. Each hop is plotted on a satellite map so you can visualize routing across cities, countries, and continents.
MAC COMPANION
Connect to NetMonitor Pro on your Mac over Bonjour. Synchronize devices, run remote diagnostics, and monitor your network from either platform. No cloud relay — everything stays on your LAN.
TIMELINE
Every scan, device change, and network event is logged. Scroll back through your network's history to spot patterns and review past diagnostics.
BUILT FOR RELIABILITY
Swift 6 with strict concurrency. Intelligent thermal throttling. Background scanning via BGTaskScheduler. Home screen and lock screen widgets for key metrics.
No data ever leaves your device. No analytics. No tracking. Just tools that work.
