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.

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.

Both features have been requested long time ago and I see them valid but due to limited free time I have to develop the app they need to way some more time.

The app does not show you any map with mobile tower. It aims only at accessing to your phone (calls, storage...).

You're wrong, it's clearly stated in app description that it helps collecting cell tower, signal and your location to contribute building open database of cell tower locations. Event the app name suggests that. Please remove your comment.

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.

The main purpose of the app is to collect data, not to present cell towers locations. There're many others which do that well. The feature you mention will be addressed in the future.
