Smoother device pairing — touch your heart-rate monitor or punch trackers to your phone to pair, name your gear, and see battery levels. Apple Watch now keeps tracking your heart rate when the screen goes dark. Your card appears on the studio TV before class starts. New "Few spots left!" alerts on the Book tab, a refreshed Home screen with your lifetime classes, and a new app icon.

- Find your gear in seconds: touch your punch trackers or heart rate monitor to your phone and the app picks out yours (punch to identify trackers, left then right). - Battery levels for your trackers and heart rate monitor. - Name your devices right after pairing; renaming trackers names the pair. - New Home stats: lifetime classes, this year and this week. - Unlinking a tracker now unlinks the pair. - Fixes a crash when a punch tracker disconnects, and other reliability improvements.
