It provides real-time insights into your personal cellular signal strength across all network types including 2G, 3G, 4G, and 5G. With its Personal Coverage Map feature, you can monitor your signal quality by location to pinpoint where your coverage is strongest or weakest. The extension also offers a Network Performance History tool, allowing you to review historical signal strength data and observe trends over days, weeks, months, or even longer. Furthermore, the Crowdsourced Network Coverage Map lets you compare your data with aggregated community insights, filtered by network type and operator, helping you anticipate coverage quality before traveling. Mobile Signal Finder values privacy and does not collect personally identifiable information like emails or phone numbers. Instead, it collects anonymized location and network performance data to support network operators in enhancing service coverage. This makes it a privacy-conscious and community-driven solution for improving your mobile connectivity awareness and experience. ## Rankings - #76,956 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_BACKGROUND_LOCATION` - `android.permission.ACCESS_COARSE_LOCATION` - `android.permission.ACCESS_FINE_LOCATION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.ACCESS_WIFI_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_PHONE_NUMBERS` - `android.permission.READ_PHONE_STATE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.REORDER_TASKS` - `android.permission.WAKE_LOCK` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.google.android.providers.gsf.permission.READ_GSERVICES` - `com.m2catalyst.signaltracker.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Review summary Users appreciate that Mobile Signal Finder can report mobile signal strength and does not show ads. However, multiple reviews highlight crashes, confusing color codes with no legend, limited network/SIM support, and invasive permission requests. Several users also report persistent issues with 5G detection and data loss on maps. The app's usability suffers due to a complex user interface, reducing its effectiveness for comparing carrier coverage. These recurring issues result in user frustration and uninstalls despite some positive aspects. ### Pros - Some users find the app useful in reporting and contributing mobile signal strength data. - App works well for identifying signal quality for the SIM inserted in the first slot on dual SIM phones. - No ads were reported by some users, improving user experience compared to other apps. - Works well to show signal strength changes when toggling data on and off. ### Cons - App crashes on launch or stops working for several users after some time. - Lack of clear legend or explanation for color codes on the map makes it confusing to interpret signal quality. - Does not support or display multiple networks or SIMs simultaneously, showing only the first SIM's data. - App requests invasive permissions such as access to phone calls and messages, causing privacy concerns. - Does not properly detect or report 5G signals despite supporting 5G network connection. - Saved data or maps do not persist, disappearing without recovery; users find this frustrating. - User interface is considered complex and non-intuitive for understanding carrier coverage or interpreting data. ## Similar extensions and apps - [Cellular Tower Map - Signal 5G](https://chrome-stats.com/d/com.appsandgamesforall.celltowermap) — 29,932 users, 3.64 / 5 - [MapSignal 5G Network Monitor](https://chrome-stats.com/d/com.kijuzdev.mapsignal) — 3,087 users - [Cellular Tower - Signal Finder](https://chrome-stats.com/d/com.cellular.finder) — 868,521 users, 4.33 / 5 - [Cell Tower Locator: Find 5G](https://chrome-stats.com/d/com.nicomelian.celltower) — 3,903 users, 4.05 / 5 - [5G Signal Strength Finder](https://chrome-stats.com/d/com.pinnedapps.lte_signal_finder_detection.four_g_five_g_speed_test.lte_signal) — 5,458 users, 1.80 / 5 - [Cell Tower Finder - 5G 4G Map](https://chrome-stats.com/d/com.swayambhutaya.celltowerfinder.map) — 3,039 users, 1.45 / 5 - [Cellular Tower : 5G/4G Finder](https://chrome-stats.com/d/prem.corta.cellulartowersignalfinderdfg) — 1,945 users, 4.00 / 5 - [Cell Tower Locator 5G, 4G, LTE](https://chrome-stats.com/d/com.celltower.locatorapp) — 81,497 users, 3.68 / 5 - [Mobile Coverage Map: 5G & 4G](https://chrome-stats.com/d/com.thumbstonelabs.signalfinder) — 813 users - [Signal Strength](https://chrome-stats.com/d/com.ruralrobo.signalstrength) — 3,500 users - [Cellular Towers Locator](https://chrome-stats.com/d/com.cellulartowers.mobileapp) — 7,318 users, 4.31 / 5 - [SignalQuest](https://chrome-stats.com/d/com.sfrmap.android) — 746 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.m2catalyst.signaltracker)
