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.

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.

Downloaded it and it's the worst app I have ever come across. Designed to block anyone who is not in the trade. It should say that they don't want individuals to use it. All I want it for is to be able to line up my mobile mast to get the best signal for my broadband. Not possible as far as I can see. The developer says that's not the purpose of the app. But there is no help to tell you that.

The app is designed to help the community to find all cell towers in their area with the help of GPS coordinates which can be later used to compute location without GPS signal. If you export the data you can review the signal strength. It isn't designed to find the best signal when stationary. Your review doesn't align with the purpose of the app.

What's new

- Try to fix exception when button cancelling export or upload.
- Improve error handling.
