From the listing uploaded by “appupdater”.

## 📶 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.

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.
