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.

If LTE Discovery helps you, a 5-star rating goes a long way — and thank you for helping map the network!
Recent changes: Fixes the Towers map so nearby towers appear instead of only the active tower, and improves upload attestation registration.

So far, so good, my hope is to retrieve my 4G LTE, Poof one day it disappeared. I'll keep you posted. Thanks to all the Dev's, 👍

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.

Great app, especially for logging, although you occasionally need to export to csv &/or email. Screenshot log folder name! Once exported I could delete the log & restart the (500 or 1000 record) log-viewer limitation. All records over time DO LOG into the csv (just not visible in the app). There are a couple other apps that better-render connected-cell & tower location data - but don't log cell-IDs as well as this app. FYI not on the iPhone app store (for Apple IOS permissioning)

Unless app, all I need is what band I'm using, and all I get is "unknown" under band: pointless app
★☆☆☆☆Ulises Vazquez· Aug 8, 2025
It doesn't detect that I paid for PRO when I have no signal or internet. That's when I need this app the most.
★☆☆☆☆Dewi Bermingham· Sep 6, 2025
Doesn't seem to work at all. Whatever I do, I'm stuck with 5g

This app has recently been crashing lately... it's almost like the RAM in my phone gets used too much 😔
