Description
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 - 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.

Great app that gives you all the information about the tower you're connected to plus shows all the neighboring towers that your phone is picking up on along with their signal strength. Lots of apps like it, but this app is laid out particularly nice and clean. I ended up buying the Pro version awhile back. This app will even show Stingrays if you know what they are and what to look for. At least on AT&T. Worth every penny.

One of the best apps, to get the cell tower location details. Thank you Developers.

After the recent update, this app only scans with the first sim. There's no option to select the other sim or both. Please fix. Update after 1 day: oh wow the developer actually reads this and updated this! Would like to be able to show the active sim (or both) on live mode notifications too. Update after 2 days: oh the new widget gives me what I want. Appreciate the developer's responsiveness!

This overhaul is horrible. The only reason that I used this app and even paid for the Pro version is because it would show direction arrow towards the connected to tower. Not anymore. NO directional arrow, but sure enough, lots of useless to me junk. Now you have to pay for Pro Plus version to see the map. Ridiculous ripoff. They are skimming the dough and the paid Pro version subscribers are left behind to lick the dust. Adding: I can't orient antenna with a phone anymore. No arrow.

Was great now just more trash - dev removed established paid account features, and moved them to a higher pay tier. I supported this guy from very early on, paid for premium account just to show support. Only used the app for 1 feature. Recent update moved that feature to some bs monthly sub tier. That's some thieving. 2 faced bs right there
