Different app versions on Transmitter and Receiver

The same version of the app must be installed on both devices in order to establish a connection.

Please proceed as follows:

  1. Please install the latest update of our app on both devices. Depending on your device, this is done via the App Store or a download from our website.
  2. Launch the app and check on both devices which version of the app is installed:
    1. Start app
    2. Miscellaneous
    3. About
    4. Installed Version:
  3. Are the versions identical, now?
    1. If so, then the connection should work now.
    2. If not, then see below for possible causes and solutions.

Causes and Solutions

Cause 1

The update was released a few hours ago and is not yet available on either device.


Unfortunately, we have no influence on how fast the respective app stores provide our updates. Some app stores have a lengthy review process that can significantly delay deployment.

In this case, please try to download the app from the same app store on both devices, if possible.

Cause 2

You signed up for our beta program through Google Play.


The beta version of our app is usually newer than the regular version of the app. Please either join the beta program with both devices or return to the regular version of the app if the beta version of the app is not available for both devices.

Cause 3

One of your devices has an Android version installed which is older than Android 4.1.


As soon as an app update only supports newer versions of Android, it can happen that only your newer device, but not your older device, installs the update. Thus, you need to install an older version of the app that is supported on both devices.

Important notes and procedure:

  1. First back up your license number if you are using BabyPhone Mobile.
  2. Then uninstall the newer version of the app.
  3. Install the older version (see download archive below).
  4. Deactivate the automatic updates of the app (e.g. via Google Play), because otherwise the older version you installed will automatically be replaced by a newer version.
