The app has a very simple interface that displays a list of the day's scheduled games and start times. When a game begins, options will become visible to tune in live to the home or away radio broadcasts, with no subscription or account required. The score and time remaining are also shown for games in progress.
This mirrors the experience of the NHL app on iPhone, which has a headphone icon in the top-right corner for accessing radio broadcasts.
That's it, really. At least for now, the CarPlay app does not feature standings, stats, news, or video, which is in the best interest of driver safety. Just like the MLB At Bat app for CarPlay, this is all about the listening experience. The 2019 Stanley Cup Playoffs begin next Thursday, April 10.
