What’s new in watchOS 7.4?

The most important feature in this update is the ability to unlock iPhone X or later models using an Apple Watch, while wearing a mask. This feature works in tandem with iOS 14.5, and removes the need to take off your mask or entering a passcode just to unlock your iPhone. However, to use Face ID for App Store, Apple Pay, and third-party apps such as banking, users still have to enter a passcode or take off their mask to use authentication. While this is not as convenient as a fingerprint scanner in the current pandemic, it is still a step up from having to enter a passcode.

Other updates include the ability to classify Bluetooth device type in Settings, audio and video streaming from Apple Fitness+ workouts to AirPlay 2 enabled TVs or set-top boxes, and ECG and irregular heart rhythm support in Australia and Vietnam.

Here are the complete release notes from Apple:

watchOS 7.4 includes new features, improvements, and bug fixes, including:

  • Ability to unlock your iPhone X and later with Apple Watch when you attempt to use Face ID while wearing a face mask
  • Option to classify Bluetooth device type in Settings for correct identification of headphones for audio notifications
  • Ability to stream audio and video content from Apple Fitness+ workouts to AirPlay 2-enabled TVs and devices
  • Support for the ECG app on Apple Watch Series 4 or later in Australia and Vietnam
  • Support for irregular heart rhythm notifications in Australia and Vietnam
