What WiFiAnalyzer is

WiFiAnalyzer is a free Android app for examining nearby Wi-Fi access points and their signals. It displays signal strength, graphs channel signals, and rates channels to help users assess the networks around them. The app supports 2.4, 5, and 6 GHz bands, with HT/VHT channel-width detection dependent on device hardware and software. Filters can narrow access points by band, signal strength, security, or SSID, and users can export access point details. A time graph tracks a selected access point’s signal over time. The app also estimates distance from signal strength and frequency using the Free-space path loss model, though obstacles and other electronic devices can affect that estimate. The maker says it does not collect personal or device information and does not require internet access. WiFiAnalyzer is licensed under GPLv3. GitHub release APKs have a published SHA-256 signing-certificate fingerprint and verification guidance. The project accepts bug reports and feedback through GitHub Discussions. It is a signal analysis tool, not a password-cracking or phishing tool.

Who it suits

WiFiAnalyzer suits Android users who want to inspect nearby access points, compare channel signals, or export network details. Its distance estimate is approximate and may be affected by obstacles and other electronic devices.

What it does well

Free Android app for Wi-Fi signal analysis.
Filters access points by band, signal, security, or SSID.
Exports access point details.
Does not require internet access, according to its maker.
Tracks a selected access point’s signal over time.

What to know first

Available for Android only.
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.

Getting started

Open the WiFiAnalyzer project website.
Use the Android app; APKs are distributed through GitHub releases.
If using a GitHub release APK, check its signing-certificate fingerprint using the project’s verification instructions.

Verdict

WiFiAnalyzer focuses on network signals, channels, and access point details rather than security attacks. Its filters, exports, and historical signal graph offer several ways to examine nearby Wi-Fi, while some features depend on device support.
