Tower Collector

About this app

Tower Collector gives you opportunity to contribute in OpenCellID.org and Mozilla Location Services projects by uploading GPS locations of GSM/UMTS/LTE/CDMA/TD-SCDMA/5G (NR) cell towers from your area. The measurements help map the extent of mobile phone network coverage. You can use the app to collect data for personal purposes and export them to various files.

Some features:
• specially optimized GPS parameters to reduce battery drain
• upload to OpenCellID.org and Mozilla Location Services (MLS) projects
• export to SD card as CSV, JSON, GPX, KML and KMZ.
• ad-free, forever!

The OpenCellID.org project goal is to create a worldwide open source database of mobile cell locations. Tower Collector gives you opportunity to contribute in OpenCellID project by uploading cell towers locations from your area. Collected data can be used to quickly locate devices without enabling GPS.

Mozilla Location Services (MLS) is an open source project, aiming to create a worldwide database of wireless network infrastructure identifiers (cell towers, WiFi access points, Bluetooth beacons) correlated with GPS locations. Aggregated cell location set is available under the public domain "Creative Commons (CC-0)" license.

Ratings and reviews

App does a good job but I wish it had: 1. A safety to avoid collecting & submitting a ton of samples (especially new one-sample towers) exactly on top of home/office. Maybe exclusion areas where e.g. collection pauses, data removed from upload, or noise added 2. Show prior submissions or tower position estimates. I understand dev saying this isn't the app's purpose, but it'd still be VERY helpful to know where data exists already (even just my own), and to target what's inaccurate.

Hello. This is a great app for me. But I have a problem with the map. I have the mobile data turned on and... the map still doesn't appear. If is a mistake made by me, can you tell me what can I do? Please. And btw, this is the perfect app for me :D

Collected data on signal strength at different locations where I was. I captured the tower identifier, but I could not get it to show me where the towers were actually located on the map.

What's new

IMPORTANT!
Mozilla have made the decision to retire the service and new measurements are no longer accepted. Read more: https://discourse.mozilla.org/t/retiring-the-mozilla-location-service/128693

The option to upload to Mozilla Location Services temporarily remains available, but I will only try to upload the measurements if custom MLS-compatible address is provided in Preferences.
