Ping, Traceroute, Speed Test
$4.99
Discover every device, and speed test in one tap — all in a stunning dark-mode dashboard designed for iPhone and iPad
10 professional network tools. Zero cloud. Zero ads. Zero subscriptions. Everything runs locally on your Mac.
NetMonitor is a complete network monitoring and diagnostics toolkit built for macOS. 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 off your machine.
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
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, and live connection events — all in one view.
DEVICE DISCOVERY
Find devices other apps miss. NetMonitor's multi-phase scanning engine uses ARP, Bonjour, TCP probes, and reverse DNS to build a complete picture of your network. See IP and MAC addresses, vendor names, open ports, running services, and connection history for every device.
10 BUILT-IN DIAGNOSTIC TOOLS
• Ping — ICMP with TCP fallback, live latency graphs, and packet statistics
• Traceroute — Hop-by-hop path analysis with timing
• GeoTrace — Visual traceroute plotted on a world map
• 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 peak speed and jitter 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.
IPHONE COMPANION
Connect to NetMonitor on your iPhone over your local network via Bonjour. Synchronize devices, run remote diagnostics, and monitor your network from either platform. No cloud relay — communication stays on your LAN.
TIMELINE & EVENT HISTORY
Every scan, device change, and network event is logged. Scroll back through your network history to spot patterns, track when devices appeared or disappeared, and review past diagnostics.
No data ever leaves your device. No analytics. No tracking. Just tools that work.
Redesigned Dashboard
A completely refreshed interface with a sleek always-dark aesthetic and glass-effect cards. The new speed test quick-card gives you one-tap access right from your dashboard.Device quick-glance widgets show your top 3 online devices on your Home Screen.
Smarter Device Discovery
A new Consumer/Pro toggle switches between a clean overview and detailed technical data for every device on your network. Devices sort by vendor or latency, each with a share button for quick export.
View any device's network timeline to track history over time.
Network Map & Profiles
Switch between saved network profiles right from the map view. A new topology visualization shows your gateway at the center with connected devices radiating outward. WAN Info and Anchor Latency cards give a clearer picture of your external connection.
iPad Layout
Fully responsive 3-breakpoint dashboard that takes advantage of the bigger screen, plus proper sidebar navigation with NavigationSplitView.
3D Room Scanner
Scan any room with your iPhone's LiDAR sensor to create a detailed 3D floor plan. Save scans as .netmonblueprint files and send them to your Mac via AirDrop or iCloud for further analysis.
Continuous measurement mode lets you walk through a space while recording signal levels in real time.
