Network Scanner: WiFi & Ports

The network scanner built for field technicians and installers.

See every device on your network, scan ports, test speeds, and monitor connections in real time. Free to use, with a one-time Pro upgrade. No subscriptions. No accounts. Your scan results never leave your phone.

Open the app and it scans. No setup, no wizard, no sign-in.

Note: Android itself requires location permission to read Wi-Fi details - it is what lets the app see your network name and find what is connected. Your location is never read and never leaves your device.

🔍 WHAT IT SCANS

- Instant local subnet discovery, running the moment you open the app
- Hardware fingerprinting and automatic manufacturer identification

- Network map showing how every device connects, at a glance - free
- Security check for exposed ports and weak spots
- Device groups for sorting by room, site, or client
- Timeline of what joined and left your network, hour by hour
- Built-in subnet calculator with CIDR adjustment and quick-select presets
- Saved scan history with device-level notes
- CSV and PDF export for documentation and handoffs

🚀 SPEED TEST

🔒 ABOUT YOUR DATA

Everything you scan stays on your device. Device names, IP and MAC addresses, open ports, notes, and saved scans are stored locally and are never uploaded, synced, or shared. There is no account to create and no server holding your network layout.

The app does collect anonymous crash reports and basic usage data through Google Firebase, so I can see what is breaking and fix it. The free version also serves ads through Google AdMob, which uses an advertising ID. Neither touches your scan results. Pro removes the ads.

As above, the location permission Android requires for Wi-Fi scanning is never used to read your location.

Built by a working security integrator who got tired of subscription bloat and toy-grade scanners. If you've ever needed to prove to a client that the network is clean, the port is open, or the drop is live - this is the scanner.
