Apple on Monday released watchOS 7.2, the second major update to the watchOS 7 operating system that was released in September. watchOS 7.2 comes more than a month after the release of watchOS 7.1.

‌‌The watchOS 7.2 update‌‌ can be downloaded for free through the dedicated Apple Watch app on the iPhone by going to General > Software Update. To install the new software, the Apple Watch needs to have at least 50% battery, it needs to be placed on a charger, and it needs to be in range of the ‌‌‌‌‌iPhone‌‌‌‌‌.

watchOS 7.2 introduces support for Apple Fitness+, Apple’s newest streaming service. Powered by Apple Watch, Fitness+ provides subscribers with studio-style workouts that can be watched on ‌iPhone‌, iPad, and Apple TV in categories that include cycling, yoga, core, strength, treadmill, and more.

Fitness+ requires an Apple Watch, with the watch connecting to the device that you’re watching the workout on to provide on-screen follow-along metrics for motivational purposes.

The update also adds a Cardio Fitness feature for the Apple Watch, which is a “strong indicator of overall health.” The feature measures VO2 max, or the maximum amount of oxygen that your body is able to consume during exercise. Measurements are done over time, and the Apple Watch and ‌iPhone‌ are able to send notifications to let you know about fluctuations in your VO2 max.

Apple Watch has previously been able to measure VO2Max, but the new feature includes support for lower ranges that have needed clinical testing in the past.

Cardio Fitness can be accessed through a new trend that’s been added to the Activity app, and it can be set up in the Health app on ‌iPhone‌. Cardio fitness levels are available for users age 20 and above in ranges that include high, above average, below average, or low, and are estimated by age. Apple sends notifications to let you know if your cardio fitness is at a low level, providing motivation to move more.

Atrial fibrillation classification is now available at heart rates above 100BPM, the ECG app is now available in Taiwan, and support for braille displays has been added.
