Apple Watch Series 12 may add all-day heart-rate tracking

Apple Watch Series 12 may bring a more meaningful health update than its familiar design suggests. Apple is reportedly testing all-day heart-rate tracking and a redesigned health-and-fitness app, according to Bloomberg’s Mark Gurman, as the company prepares the Series 12 and Apple Watch Ultra 4 for its September product cycle. 9to5Mac\n\nThe reported heart-rate change would have the sensor collect readings throughout the day instead of primarily during workouts and at intervals. More frequent data could give Apple a stronger base for long-term wellness trends, but the report does not establish how often the watch would sample, how the change would affect battery life, or whether it would be limited to the new models.\n\nGurman also says Apple is working on a new fitness and health app that would surface more wellness-related metrics, taking a more holistic approach similar to apps from Whoop and Oura. That would be a notable shift from presenting the Apple Watch experience largely through individual measurements and Activity rings, although the final design and feature set remain unknown.\n\nThe same report says Apple is testing a ceramic version in white and dark gray, alongside new band colors and configurations. That claim builds on earlier reporting about a possible ceramic case, but neither the case material nor the finishes have been confirmed by Apple.\n\nThis is still a report about products in development, not an announcement. Apple has confirmed neither the Series 12 nor Ultra 4, and it has not said whether either watch will receive these features. The company’s September 9 event is expected to provide the next firm details, while a larger design change is reportedly being held for a later Apple Watch generation.
