WiFi Analyzer & Network Tools

A complete WiFi analyzer and network scanner in one app. See every device on your LAN, find the least crowded WiFi channel, run a speed test, and reach for the classic network tools (ping, port scan, DNS lookup) when something breaks.

NETWORK SCANNER
Scan your WiFi or LAN and list the devices connected to it. Each device shows its IP address, the hostname it advertises, the vendor behind its MAC address when it is recognised, how many ports are open, and a device type guess: router, phone, computer, media streamer, printer, camera, NAS or smart home hub. Discovery combines four techniques so quiet devices still turn up: the ARP table, mDNS service browsing, UPnP and SSDP multicast, and an active TCP sweep of the subnet. Scan progress is live and you can cancel at any time.

WIFI ANALYZER
Scan the WiFi networks around you and see SSID, BSSID, channel, band and signal strength in dBm, sorted strongest first. A congestion score is calculated for the 2.4 GHz and 5 GHz bands, and the analyzer recommends the 2.4 GHz channel to move your router to. The sweet spot finder lets you log a named signal reading for each room and charts them together, so you can see where coverage actually drops.

SPEED TEST
Measure your internet connection with a live gauge. You get download, upload, ping, jitter and packet loss in one run. Every speed test is saved to history and charted over time, so you can prove whether the connection really got slower.

NETWORK TOOLS
Ping any host or IP address with TCP probes and see min, average and max round trip time.
Port scanner for any address on your network, with a port range you choose and common service names labelled.
DNS lookup for A, AAAA, CNAME, MX, NS, TXT and SOA records, plus reverse DNS from an IP address back to a hostname.

SECURITY CHECKS
The security screen reviews the devices from the last scan and flags risky open ports such as Telnet, FTP, SMB, RDP and VNC, explains why each matters and suggests what to do. A hidden camera check looks for camera vendor MAC prefixes, RTSP and other control ports, and camera-style mDNS services, then scores how likely each match is.

EVENT LOG
Every finished scan is written to an event log with the device count and the subnet scanned, and the log has search and type filters.

EXTRAS
Wake on LAN sends a magic packet to wake a sleeping PC, NAS or media server.
Workspaces let you save named setups for home, office or a client site and switch between them.
Dark, light and system themes.

EXPORT AND REPORTS
Export the device list as CSV with IP, MAC, hostname, vendor, type, risk level and open ports, or build a multi-page PDF with a summary and the full device table. The CSV goes to the Android share sheet; the PDF opens in Android's print and save dialog.

PERMISSIONS
Location and nearby WiFi devices: Android requires both before any app can read WiFi network names or run a WiFi scan. Without them the WiFi analyzer returns nothing. None of the app's own features read your GPS position.
Internet, network state, WiFi state and control, and multicast: used for discovery, DNS lookups and the speed test. Android does not prompt for these.
Notifications, camera, Bluetooth and legacy storage: all optional. Leave them ungranted on the setup screen and every tool above still works.
Foreground service and wake lock permissions are declared but unused in this version. Nothing scans in the background.

The app is free and supported by ads. It includes the Google AdMob SDK, so ad requests go to Google and you are asked for ad consent where that is required.
