WiFi Test Master is a network diagnostic tool for Android that helps you measure signal strength, check channels, and troubleshoot connectivity. WiFi Test Master shows real-time RSSI, channel usage, and basic speed metrics to help you pinpoint weak coverage areas. WiFi Test Master supports common diagnostics such as ping and traceroute and lists connected devices and access point details.

Key features

• Signal strength meter with dBm readout and short-term history
• Channel scanner and interference visualization to identify crowded frequencies
• Basic speed test with download/upload estimates and latency
• Ping and traceroute diagnostics for network path analysis
• Device and access point scanner showing SSID, BSSID, security type, and frequency
• Logs and charts for local review and troubleshooting

How it works

The app performs on-device scans using Android Wi-Fi and network APIs to gather measurements; tests that require internet access use public servers. Diagnostics focus on metrics and topology rather than packet contents. Use the app to compare locations and adjust router placement or channel settings.

Permissions and privacy

The app requests Wi-Fi state and location permissions when needed to detect nearby networks. Collected diagnostic data is stored locally and can be exported only if you choose to share logs. No account is required for core functionality.
