Apple has rolled out watchOS 7.3 bringing ECG to more countries and a new Unity watch face. Among the new features included in watchOS 7.3 is Time to Walk – an audio experience found in the workout app that lets Apple Fitness+ subscribers listen to stories as they walk.
The update also includes a Unity watch face, which creates a unique face by changing shapes throughout the day.
In addition, Apple has introduced specific features for users in Japan, Mayotte, Philippines, and Thailand, including the ECG app and irregular heart rhythm notifications.
Apple says watchOS 7.3 also fixes a bug where Control Center and Notification Center apparently became unresponsive when Zoom was enabled.
In conjunction with the release of watchOS 7.3, Apple also unveiled the Black Unity Collection, which the company says is meant to “celebrate and acknowledge Black history and Black culture.” Included in the collection is a limited-edition Apple Watch Series 6, a Black Unity Sport Band, and the aforementioned Unity watch face. The entire collection, including the Unity watch face, is modelled after the colours and design of the Pan-African flag. The physical Black Unity Collection products will be available starting February 1, while the Unity watch face is already available for current Apple Watch wearers to use.
Aside from watchOS 7.3’s ties to the Black Unity Collection, the latest version also includes a security update that’s available for Apple Watch Series 3 products and later. The details on what this security update specifically provides is rather sparse, but Apple did disclose that “a race condition was addressed with improved locking.”
In addition to beefed up security for Apple Watches, security updates for other popular products like iPhones, Apple TVs, and iPads were also provided through iOS 14.4 and iPadOS 14.4, macOS 11.1, and tvOS 14.4.
