## 📶 WiFiViewer — Understand Your Wi-Fi and Network

WiFiViewer is an Android app for analyzing nearby Wi-Fi access points, discovering devices on your local network, and diagnosing your Wi-Fi environment.

Go beyond simply checking signal strength. WiFiViewer provides detailed information about Wi-Fi standards, channel width, security, signal strength, and channel congestion.

### 📶 Advanced Wi-Fi Analysis

Scan nearby access points and view detailed information including:

• Wi-Fi 6 / 6E and Wi-Fi 7 support • Channel widths from 20 to 320 MHz • Center frequency and signal strength • Security types including WPA3 and OWE • Security diagnostics and performance ratings • Signal strength history with RSSI graphs

Tap any access point to view its detailed information, including technical capabilities and performance details.

### 🔍 Discover Devices on Your LAN

WiFiViewer uses multiple discovery methods instead of relying on Ping alone.

• TCP port scanning • HTTP information • mDNS / DNS-SD • SSDP / UPnP

By combining information from multiple protocols, WiFiViewer can identify devices such as routers, printers, media devices, and cameras.

Your own Android device can also be displayed with detailed information such as its OS version and device model.

### 📊 Wi-Fi Channel Analysis

Analyze channel congestion based on nearby access points.

WiFiViewer considers not only the number of APs, but also the interference range of wide channels such as 80, 160, and 320 MHz.

It also analyzes the 2.4 GHz, 5 GHz, and 6 GHz bands and recommends channels with relatively low interference based on the surrounding environment.

Your currently connected access point and channel are clearly highlighted for easy identification.

### 🎨 Modern and Easy-to-Use UI

Built with Material Design 3 for a clean and modern interface.

WiFiViewer is optimized for Android 15 and 16, including Edge-to-Edge and Predictive Back, and supports Light/Dark themes and Dynamic Color on Android 12 and later.
