Apple watchOS 7.2 brings crucial ‘Cardio Fitness’ health feature

Apple on Tuesday (December 15) released the much-awaited watchOS 7.2 along with iOS 14.3 for all eligible Watches and iPhones in India.

The new watchOS 7.2 brings lots of features including support for braille displays with VoiceOver, Fitness+ subscription, ECG (Electrocardiogram) app to newer markets, and more.

It also brings a crucial ‘Cardio Fitness’ feature. It makes use of the Apple Watch’s sensitive sensors such as optical heart sensor, GPS, and the accelerometer, to track the user’s physical activity and VO2 max levels all through the day.

For the uninitiated, VO2 max is the maximum rate of oxygen consumption measured during incremental exercises. If the Cardio Fitness reach lower levels, Apple Watch will instantly notify the user to take the medical help.
