Apple Watch users can now view their cardio fitness levels in the Health app on iPhone, and receive a notification if it falls within the low range. According to the company, with iOS 14.3 and watchOS 7.2 software updates, people can measure low cardio fitness for dramatic long-term health benefits. “Using its advanced sensors, Apple Watch now brings estimation of low cardio fitness levels from clinics directly to a user’s wrist, so people have more insight into how they can improve their long-term health through daily activity,” Jeff Williams, Apple’s chief operating officer, said in a statement late on Monday. With watchOS 7, Apple Watch uses multiple sensors, including the optical heart sensor, GPS and the accelerometer to estimate lower levels too. watchOS 7 also allows Apple Watch to take cardio fitness measurements as users walk throughout the day, whether or not they are tracking a workout. “With this innovation, Apple Watch is better able to measure VO2 max for users with low cardio fitness, who may not complete high-intensity workouts,” the company said.
