LTE Discovery

LTE Discovery turns your Android phone into a powerful, real-time cellular signal analyzer — and a live window into the coverage around you.

Whether you're an RF engineer, a network enthusiast, or just chasing a stronger connection, LTE Discovery shows you exactly what your phone's radio is doing right now — and lets you explore real-world coverage and cell towers mapped by the community.

REAL-TIME SIGNAL ANALYSIS

- Live 5G NR, LTE, 4G, 3G, GSM and CDMA data as it changes

- Band, EARFCN / NR-ARFCN, bandwidth and exact frequencies

- RSRP, RSRQ, SINR, RSSI, ASU and signal level

- Cell identifiers: GCI, PCI, TAC, PLMN, MCC / MNC

- 5G NR (NSA and SA) detection and carrier aggregation

- A visual spectrum view that shows where your carrier sits on the band

CROWDSOURCED COVERAGE & TOWER MAPS (new)

- Coverage map — real-world signal strength across your area, built from measurements contributed by people using the app

- Tower map — find nearby cell sites with carrier and band details

- Snap the map to your location and refresh it with a tap

- The more everyone drives and walks with the app on, the more complete the maps become. Contributions are anonymous, and you can turn them off anytime.

HANDY TOOLS

- EARFCN / channel calculator with precise uplink and downlink frequencies

- Save and review detailed signal logs over time

- Live signal readout right in your notification bar

LTE Discovery's analyzer and maps are free to explore. Go Pro to unlock advanced coverage-map filters (by band and metric) and help support the small team building it.

GOOD TO KNOW

- Some advanced data depends on your specific phone and carrier — those are hardware and OS limitations, not the app.

- Anonymous contributions power the coverage and tower maps. We never sell information that identifies you.
