The Apple Watch Series 4’s ECG feature is now available to US users : UPDATE: Initial reports about the ECG feature being activated on the Apple Watch Series 4 with the WatchOS 5.1 update have been incorrect. ECG will come to the device at a later time. Furthermore, Apple has halted the Watch OS 5.1 update release due to technical issues. Original story follows below.
Since the release of the original Apple Watch back in 2015, Apple has continued to bake health and fitness related features into its popular wearables line. However, with this year’s Series 4 model, this reached a whole new level with the new electrocardiogram (ECG) feature.
Prior to announcing the Series 4 models, Apple was granted approval by the FDA which essentially makes the watch the first ECG wearable on the market. The company did confirm that the feature wouldn’t be available immediately but did promise to introduce it in the near future. Now, that day is finally here as the Cupertino-based giant has begun activating the feature across Apple Watch Series 4 models as part of the WatchOS 5.1 update that is rolling out right now.
Aside from the ECG feature in the US, WatchOS 5.1 introduces support for Group FaceTime via FaceTime Audio alongside a set of single color watch faces. The update also includes more than 70 new emoji characters.
