@voks Thanks for asking! Correct that to "retired". Then ask why I didn't add the NonFreeNet anti-feature while F-Droid did (no uploads possible anymore).
NeoStumbler collects and, for now, lets you export collected data. There are "custom servers" in preparation for MLS/Ichnaea. As soon as such are up, running and useful, NeoStumbler will add them.
TowerCollector did something comparable, you can enter a custom URL for upload. But then, TC also supports OpenCellID, so it has additional use.
