WiFi Spy: Who's on My WiFi

Who is on my WiFi? WiFi Spy answers that in seconds, then tells you exactly how healthy and secure your network is, in plain language.

ONE TAP FULL CHECK
Tap "Run full check" and WiFi Spy scans your network for connected devices, inspects your router and measures your internet speed. You get a network score from 0 to 100 with a clear breakdown: Security, Devices, Signal, Speed and Interference.

SEE WHO IS USING YOUR WIFI
• Find every device connected to your WiFi: phones, laptops, smart TVs, speakers, printers, cameras and IoT gadgets
• Device name (when available), manufacturer, IP address and MAC address
• Mark devices as "Mine" or "Not mine" with one tap
• New and unrecognized devices are highlighted so they stand out on your next scan
• History of every device that has joined your network

WIFI SECURITY CHECK
• Checks your WiFi encryption (Open, WEP, WPA, WPA2, WPA3) and explains what it means
• Router check: finds risky services such as Telnet and FTP, and tells you if UPnP is enabled
• Private DNS status for this phone
• Every issue comes with a simple "what to do next" recommendation

WIFI ANALYZER
• Signal strength (dBm), link speed, WiFi standard and band (2.4 / 5 / 6 GHz)
• Channel analyzer: see how many nearby networks share your channel, with a congestion chart and the best channel to switch to
• Nearby networks list with signal and security
• Tip when your router also offers a faster 5 GHz band

INTERNET SPEED TEST
• Download, upload and ping
• Instantly see what your connection is good for: browsing, HD video, 4K video, video calls and online gaming

NETWORK DETAILS
IP address, gateway, subnet mask, DNS servers, IPv6, MTU, BSSID, channel width and more, with one-tap copy.

PRIVATE BY DESIGN
Device discovery runs locally on your phone. Your scan results are not uploaded. The speed test only contacts a public test server to measure throughput.

Why does WiFi Spy ask for location? Android requires location permission for any app that reads WiFi network details. WiFi Spy uses it only to read your network information and never tracks your location.

WiFi Spy is a network scanner and analyzer for your own home network. Use it only on networks you own or are allowed to manage.
