SignalMetrix

SignalMetrix is a professional network quality monitor for Android, built for field engineers, network technicians and advanced users who need precise, real-time data about their 4G/5G or Wi-Fi connection.

The app continuously measures latency (RTT), packet loss and jitter towards a configurable endpoint, using three test modes: ICMP ping, HTTP HEAD request or TCP socket connection. Every sample is paired with live signal readings - RSRP, RSRQ, SINR and Cell ID for cellular networks; SSID, RSSI, link speed and band frequency for Wi-Fi.

SignalMetrix is designed to assess connection stability over time, not just a single snapshot. Rolling min/avg/max statistics and a live scrolling chart let you instantly spot degradation, intermittent drops or coverage gaps as they happen — even with the screen off, thanks to a persistent background service.

Every measurement is GPS-tagged and plotted on an interactive map with colour-coded markers reflecting signal and latency quality. A satellite layer is also available for field surveys. Past sessions are stored in a searchable history with full detail view, including RTT chart, signal graph and per-point map.

All session data can be exported as CSV with a single tap and shared via any app on the device, making it easy to archive results, hand them off to a colleague or analyse them in a spreadsheet.

Clean Material 3 dark interface, monospaced numeric readouts and responsive layout for both phones and tablets. Available in English and Italian.
