Yes there will be!
The AppleTV app is currently in development and we're expecting it to become available around February, 2021.
As we know from some our TV show's, timelines may slip. We will be excited to have it come available, so we'll be shouting it from the rooftops when it's ready.
Let us know if you want to be notified by contacting support.
In the meantime, you can use AirPlay to stream our content from your mobile device to your TV.
