SignalSentry

SignalSentry is a mobile app that continuously measures real-world mobile network quality and turns it into evidence you can use. It logs signal strength, band, latency, jitter, packet loss, and throughput, then correlates drops with location, time, device state, and whether you were on 5G/4G/Wi‑Fi. The app generates a simple “service reliability report” you can share with your carrier, employer, or landlord, and it suggests practical fixes (e.g., force LTE in specific zones, enable Wi‑Fi calling, best placement for a hotspot) without pretending it can magically improve coverage. For teams, it supports shared maps for field staff so operations can choose better routes and know which carrier performs best in each area. This is not a speed-test toy; it’s a lightweight monitoring tool designed for repeatable, defensible measurements.
