The latest software update for Apple’s Watch line dubbed watchOS 7.3 will be available to download later today. It brings a new Unity watch face collection that pays homage to the Pan-African flag which ties in with Apple’s Black History Month initiatives.
In addition, the new update unlocks the electrocardiogram (ECG) and irregular heart rate rhythm features for Apple Watch Series 4 and above in Japan, Mayotte, the Philippines, and Thailand.
Apple Fitness+ subscribers can also expect to see the new Time to Walk feature which helps you relax on walks with cameos from celebrities. Other updates include performance improvements and bug fixes for Control Center and Notification Center.
