Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 4.2 MB, so it installs quickly even on modest connections.
This build is signed by "Adam Zamojski" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Tower Collector gives you opportunity to contribute in OpenCellID.org, BeaconDB and @t0stbrot 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, BeaconDB and @t0stbrot 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 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.
