About this app

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.

Questions or a problem to report? Use the in-app support option and we'll help.

If LTE Discovery helps you, a 5-star rating goes a long way — and thank you for helping map the network!

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.

Sorry the old in-app-upgrade got lost in the the transition to the new app - the new update should rectify that. The compass is gone, but you should find the new tower location to be better with more information to the tower you are connected to, including sector info if we got enough data to compute it. - Spence

Was one of my favorite apps until the recent update. this app was never about a flashy UX, it was about the date. I can't even get the live band number in my status bar anymore! That was one of the best features. Also how all that interesting data that I paid extra to see is gone in favor of some stupid graphs that are the same as 10 other apps that focus on this niche. I no longer have any reason to support this app and I don't even need it installed, since I have apps that do the same thing.

Great App!. First, I like the fact that you can have your phone's signal rate, strength, and Cell location etc., with the app's overlay ability on the top of your phone's screen at any transparency of your choosing. Second, I like all the many signal metering choices, or options you can apply, or choose to monitor at any given time rate. *Tip; Besides just clicking on and off, you must know that behind those choices there are many, many more options to choose from i.e., you must click on the option's link in order to get behind and open up these many more options. To the developer (s), fantastic job! Please keep up the good work, and develop others.
