WiFi Sonar: Network Scanner

WiFi Sonar shows which devices are connected to your WiFi and how your connection is performing, all in one app. Scan your network in seconds, check open ports, measure speed and latency, and troubleshoot with built-in network tools.

WHO IS ON MY WIFI?
• Network scanner: find the devices on your local network in seconds
• Device details: IP address, device name (when the device shares it), open ports and online status
• Mark devices as trusted; newly joined devices stand out with a "NEW" label
• Give devices custom names and room tags, keep the list tidy with search and filters
• Share the device list as CSV

SECURITY
• Open port scan: risky ports such as FTP, Telnet and RDP are flagged, with a plain explanation of each risk
• Security score for each device
• IP camera (RTSP) stream viewer: check the cameras on your network
• Hidden camera detection: uses your phone's camera to help you look for the infrared (IR) LEDs found in many hidden cameras
• Bluetooth scanner: nearby devices and trackers such as AirTag, SmartTag and Tile

PERFORMANCE
• Internet speed test: download, upload and ping, saved to your history
• Ping monitor: live latency graph, jitter and packet loss
• Bandwidth monitor: watch device activity live

NETWORK TOOLS
• Network topology: your network on a visual map
• Traceroute: see the path your packets take
• Whois and DNS lookup (domain ↔ IP, reverse DNS)
• DNS benchmark: compare response times of popular DNS servers
• IP lookup: your public and local IP details
• Subnet calculator (CIDR)
• Wake-on-LAN: wake your computer over the network
• Router panel: open your router's admin page in one tap
• History: speed test trends and device events (new, online, offline)

WHY WIFI SONAR?
• Scans run on your local network; your device list stays on your phone
• Clean, modern interface with a dark theme
• 7 languages: English, Turkish, German, French, Spanish, Italian, Arabic

NOTES
• iOS does not allow apps to read MAC addresses or scan nearby WiFi channels, so manufacturer info, channel analysis and signal maps are not available on iPhone.
• Network scanning requires Local Network permission.
• Hidden camera detection is an aid; it cannot guarantee finding every camera.
• WiFi Sonar is free and contains ads.
