Tower Collector

About this app

Tower Collector gives you opportunity to contribute in OpenCellID.org and BeaconDB 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 BeaconDB 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.

BeaconDB is an a public database that collects location information about common wireless infrastructure (cell towers, WiFi access points, Bluetooth beacons). The cell tower data you contribute will be aggregated and released to the public under the "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.

house for telling you the towers you connect to and their identifications. which can be cross reference between other apps which do the same thing and sometimes you'll find that some towers connect to you kilometers away while there are other towers that are mere meters away. and then there are some towers that you have connected to in one area of town and then again in area all the way across town kilometers away but nowhere in between. which seems bizarre...

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.
