What WiFiAnalyzer is
WiFiAnalyzer is a free Android app for examining nearby Wi-Fi access points and signal conditions. It identifies access points and displays their signal strength, graphs channel signals, and rates networks’ channels. It supports the 2.4, 5, and 6 GHz bands, with HT/VHT channel-width detection dependent on hardware and software support. Filters can narrow access points by band, signal strength, security, or SSID, and the app can export access point details. A time graph follows the signal strength of a selected access point. WiFiAnalyzer estimates distance using signal strength and frequency with the Free-space path loss model, but obstacles and other electronic devices can affect that estimate. The maker says the app needs no internet access and does not collect personal or device information. It is licensed under GPLv3, and the project publishes a SHA-256 signing-certificate fingerprint and verification instructions for APKs distributed through GitHub releases. The project accepts bug reports and feedback through GitHub. It is for analyzing Wi-Fi signals, not for password cracking or phishing.
Good
- Identifies nearby access points and signal strength.
- Graphs channel signals and rates channels.
- Filters access points by band, security, or SSID.
- Exports access point details.
- Maker says it needs no internet access.
Watch out
- Channel-width detection depends on hardware and software support.
- Distance estimates can be affected by obstacles and electronics.
- It is not a password-cracking or phishing tool.
Who it suits
It suits Android users who want to inspect nearby access points, compare channel signals, and export access point details. Distance estimates should be treated cautiously because obstacles and other electronic devices can affect accuracy.
Verdict
WiFiAnalyzer focuses on Wi-Fi signal and channel analysis, with filtering, export, and signal history on Android. Its distance estimate has stated accuracy limits, and it is not a security attack tool.
