Corona-Warn-Companion app

Corona-Warn-Companion is Sports & Health tool that is open source under the GPL-3.0-only license.

Corona-Warn-Companion can (and does) work independently of the official CWA, but it needs input from something that collects Bluetooth RPIs. That can be…

  • the official Corona app or F-Droid's Corona Tracing app using Google Mobile Services (root required to access its DB)
  • the official Corona app or F-Droid's Corona Tracing app using microG (no root required: data can be shared from microG)
  • F-Droid's Corona Tracing app stand-alone (root required until microG's update is integrated)
  • RaMBLE (no root required)

Corona-Warn-Companion is intended to help you to better understand warnings of the Corona-Warn-Apps.

ATTENTION: To access the same recorded encounters as the official Corona-Warn-App, this app requires ROOT permissions. Without root permissions, the app can only be used together with the RaMBLE app, or with the CCTG app / microG.

For CWA, ''Corona-Warn-Companion'' currently covers via the German servers…

  • Croatia
