NeoStumbler is an Android application for collecting locations of cell towers, Wi-Fi access points and Bluetooth beacons.

NeoStumbler can contribute data to geolocation services with an Ichnaea-compatible API to provide geolocation capabilities for use cases such as indoor positioning, custom Android ROMs, and Linux-based operating systems. An example of such geolcoation service is beaconDB.
