• Optional donation if you'd like to support development

Code Red: Network Tools is a complete network toolkit with a neon instrument-panel look. Tap any tool on the home grid to start, or tap the ? on a tile to see what it does.

NETWORK SCANNER
• Find the devices on your network: phones, TVs, printers, cameras, NAS drives, smart plugs and more
• Identifies devices from what they announce (mDNS/Bonjour, UPnP, WS-Discovery, NetBIOS) and shows why: "Chromecast, from its mDNS model record"
• Vendor lookup, open ports, web and TLS details, services
• Ping radar and a sortable device list
• Timeline of new devices, arrivals, departures and port changes
• Optional background checks with an alert when an unknown device joins

WI-FI TOOLS
• Wi-Fi scanner: every nearby network with security (WPA2/WPA3/WEP/open), WPS, Wi-Fi generation, band, channel and vendor
• Signal and band analyzer: live signal graph, channel congestion and the best channel for your router
• Walk test: compare signal strength room by room

INTERNET TOOLS
• Speed test: download, upload, latency and jitter
• Connection doctor: step-by-step check of Wi-Fi, router, DNS, internet and captive portals, with plain-English advice
• Latency monitor: live ping to several hosts at once, with loss and spikes
• Public IP: your IP address and a check for carrier-grade NAT
• DNS benchmark: find the fastest DNS server for you
• NTP time check

PRO NETWORK TOOLS
• Ping, traceroute with a route diagram, port scanner with banners
• DNS lookup for any record type and server
• HTTP and TLS inspector with timing breakdown and certificate chain
• MTU finder, subnet calculator, TCP/UDP console
• Wake-on-LAN
• UPnP port mapping audit: see which devices opened ports on your router
• Command bar for power users: "ping printer", "ports nas top100", "dig example.com mx"

PRIVACY AND SECURITY TOOLS
• Hidden camera detector: checks the network, nearby Wi-Fi hotspots and Bluetooth for camera hardware, plus a magnetic sweep and a lens-glint guide
• Bluetooth scanner: nearby devices, beacons and trackers such as AirTag, Tile and SmartTag
• App traffic monitor: see which apps on this phone contact which domains, spot trackers and block them. It uses a local VPN on your phone only; nothing is sent anywhere else

PRIVATE BY DESIGN
• Your devices, scans and results stay on your phone
• No analytics, no tracking, nothing uploaded
• Internet tests (speed test, public IP, connection doctor) run only when you start them and tell you which service they use
• Export your inventory as CSV or JSON

Only scan networks you own or have permission to check.
