I'd suggest using the term "channels" rather than "apps". It corresponds better to the corded model.
Apps makes it sound like you need to use a dedicated application and "authentication" to access the content. Instead, you're using one app (be it Vue, SlingTV, DIRECTV Now, etc) and freely moving from channel to channel within that app. Of course if the service requires you to make significant use of apps to access available content, that should be prominently noted (and perhaps points deducted).
