ScanFi : WiFi Analyzer and Sur for Android

ScanFi is a wireless network analyzer designed for Android devices that provides users with comprehensive insights into their Wi-Fi networks. This utility allows for passive scanning without needing to connect to any access point, making it an ideal choice for users seeking detailed network information. Key features include graphical representations of network activity, signal strength measurements, and access point details such as SSID and MAC addresses. The app also offers a 60-second history graph for specific access points and channel ratings to help identify optimal transmission channels.

In addition to basic analysis, ScanFi enables users to create Wi-Fi strength surveys using default or custom floor maps sourced from their gallery. Users can assess their average download speed and locate open access points, as well as discover unknown or hidden networks. It is essential to understand that ScanFi functions solely as an analyzer and does not facilitate Wi-Fi connections. Furthermore, the scanning capabilities for 2.4GHz or 5GHz frequencies depend on the hardware capabilities of the Android device.
