Tower Collector

Join the community and collect cell towers locations from your area

New in version 2.8.3

- Add option to disable listening for my location on the map.
- Add option to start collecting on app start-up.
- Add legend for the map.
- Fix collector crashing when there's no signal (Android bug).
- Fix animation to last measurement on the map if another animation is in progress.

Tower Collector gives you opportunity to contribute in OpenCellID.org and
Mozilla Location Services projects by uploading GPS locations of
GSM/UMTS/LTE/CDMA 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 CSV or GPX 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 or GPX
* 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.
