Apple has been gradually rolling out ECG support to more countries with each watchOS update. When it was first launched with Apple Watch Series 4, ECG was only available in the United States. Now, with ECG app roll-out to Japan, Mayotte, Philippines, and Thailand, it is available in 67 countries and regions, alongside irregular heart rhythm notifications.

This new software update also includes a new dynamic Unity watch face that changes its shape throughout the day as you move more. Unity watch face has been designed by Apple to celebrate and acknowledge Black history and culture and is accompanied by the launch of a limited-edition Apple Watch Series 6 and Black Unity Sport Band.
