NetMonitor Mobile: Professional Network Diagnostics. No Cloud. No Subscriptions.

NetMonitor is a professional network monitoring and diagnostics toolkit built entirely for your device. No accounts. No cloud. No ads. No subscriptions. Just powerful network tools that run locally and respect your privacy. Network Dashboard See your entire network at a glance. A live health score grades your connection quality in real time, combining latency, packet loss, and DNS responsiveness into a single number. Monitor gateway reachability, public IP, ISP details, jitter spectrum, and live events — all on one screen. Device Discovery Scan your local network and see every connected device in seconds. NetMonitor uses a multi-phase scanning engine — ARP, Bonjour, TCP probes, SSDP, ICMP, and reverse DNS — to find devices other apps miss. View IP and MAC addresses, vendor identification, open ports, running services, and connection history for each device. Network Map A visual overview of your entire network topology. See all active nodes with real-time status indicators and response times. Tap any device for full details, port scans, and quick actions. 10 Built-In Diagnostic Tools Everything you need without switching apps: • Ping — ICMP with TCP fallback, live latency graphs, and packet statistics • Traceroute — Hop-by-hop path analysis • GeoTrace — Visual traceroute plotted on a world map via MapKit • World Ping — Test reachability from 20+ global nodes simultaneously • Port Scanner — TCP scanning with preset and custom port ranges • DNS Lookup — Query A, AAAA, MX, NS, TXT, and CNAME records • Speed Test — Download and upload throughput with historical tracking • WiFi Heatmap — Walk-around signal survey with floorplan overlay • WHOIS — Domain registration and ownership lookup • Bonjour Browser — Discover mDNS services on your network WiFi Heatmapping Import a floorplan or use freeform mode, then walk around to map signal strength across your space. Identify dead zones and optimize access point placement with real data instead of guesswork. GeoTrace See the physical path your traffic takes. GeoTrace plots each hop on a satellite map so you can visualize routing across cities, countries, and continents. Mac Companion Connect to NetMonitor on your Mac over your local network via Bonjour for extended capabilities. Synchronize devices, run remote diagnostics, and monitor your network from either platform. No cloud relay — communication stays entirely on your LAN. Timeline & Event History Every scan, device change, and network event is logged. Scroll back through your network's history to spot patterns, track when devices appeared or disappeared, and review past diagnostics. Built for Professionals NetMonitor is built with Swift 6 and strict concurrency for reliability. The multi-phase scan engine throttles intelligently based on thermal state and connection budget. Background scanning with BGTaskScheduler keeps your network data fresh. Widgets bring key metrics to your home and lock screen. Whether you manage enterprise infrastructure, run a homelab, develop networked apps, or just want to understand what's on your WiFi — NetMonitor gives you visibility without compromises. No data ever leaves your device. No analytics. No tracking. Just tools that work.
