NeoStumbler is an Android application for collecting locations of cell towers, Wi-Fi access points and Bluetooth beacons to geolocation services, which have an API compatible with Ichnaea (i.e. Mozilla Location Services).

There are two variants available:

• full - includes all features
• fdroid - does not include closed components (i.e. Google Play Services)
  • Features missing: fused location provider and automatic scanning

APKs of the application can be downloaded from Releases page.

The fdroid variant is also available from F-Droid or alternatively from IzzyOnDroid. Reproducible builds are used for building NeoStumbler on F-Droid, which means that it's possible to upgrade an existing installation to a newer version from an alternative source.

Updates for the full variant have to be manually checked and downloaded from the Releases page. The fdroid variant can be automatically updated by the F-Droid application

• Supports latest Android versions
• Collect data for cell towers, Wi-Fi access points and Bluetooth beacons
• Service for collecting data
  • Can be started automatically while moving (if using the full variant and Google Play Services are available)

The application has two product flavors:

• full - includes all features
• fdroid - features dependent on closed-source components (i.e. Google Play Services) are removed
