WiFiAnalyzer
What it is
WiFiAnalyzer is a free Android application for examining nearby Wi-Fi access points and signal conditions. It displays signal strength, graphs channel signals, and rates Wi-Fi channels. The app supports the 2.4, 5, and 6 GHz bands, plus HT/VHT channel-width detection when hardware and software support it. Users can filter access points by band, signal strength, security, or SSID, and export access point details. A time graph follows a selected access point's signal over time. WiFiAnalyzer also estimates distance from signal strength and frequency using the Free-space path loss model; obstacles and other electronic devices can affect the estimate. The maker says the app does not collect personal or device information and does not require internet access. It is licensed under GPLv3. For APKs distributed through GitHub releases, the project publishes a SHA-256 signing-certificate fingerprint and instructions for checking it. The project accepts bug reports and feedback through GitHub Discussions. WiFiAnalyzer is not a password-cracking or phishing tool.
For and against
For
- Graphs channel signals and rates channels
- Filters access points by band, signal, security, or SSID
- Exports access point details
- Maker says it collects no personal or device information
Against
- Android only
- Channel-width detection depends on hardware and software support
