How can I tell whether the app is connected to the server?

A colored stripe (or the absence thereof) below the title bar indicates the connection status:

  • Red: Threema is currently not connected to the server. This is usually due to problems with the Internet connectivity of your phone (e.g., when you have no 3G reception or if you are connected to a broken Wi-Fi network or to a Wi-Fi hotspot that requires login). Threema will keep trying to establish a connection every 10 seconds.
  • Orange: Threema is connecting to the server. A response has been received (i.e., a connection has been established), but the login process has not completed yet. If this status persists for more than a few seconds, it's usually due to a slow or unstable Internet connection.
  • No stripe: Threema is connected to the server. New messages will appear instantly.
