About LTE Discovery 7.4.40
LTE Discovery turns your Android phone into a powerful, real-time cellular signal analyzer — and a live window into the coverage around you.
Premium
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
- Home screen widgets for Live Mode signal details and spectrum view
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.
