Apple offers a trio of updates for iOS, iPadOS, and watchOS
Besides iOS 14.3, the update includes watchOS 7.2. Combined with iOS 14.3, you can now monitor the level of your cardio fitness via the Health app on the iPhone and receive a notification on the Apple Watch if your VO2 max level is low. A reading considered low could be a sign of upcoming cardiovascular disease and a warning from the Apple Watch could be another life saver. The VO2 Max is the maximum amount of oxygen a person can use during exercise. This figure can be improved by doing physical workouts.
Apple disseminated a total of three updates on Monday including iOS 14.3, iPadOS 14.3 and watchOS 7.2,
