Apple Tuesday said Apple Watch users will now be able to receive cardio notifications on their smartwatch if fitness levels fall within the low range. Notably, the feature is available with iOS 14.3 and watchOS 7.2 updates.
“Breakthrough technology released in watchOS 7 allows Apple Watch to measure low cardio fitness easily, and today cardio fitness notifications empower users to be more active for dramatic long-term health benefits,“ said Apple.
With watchOS 7, Apple Watch uses multiple sensors, including the optical heart sensor, GPS, and the accelerometer, to estimate lower levels, too, said Apple.
WatchOS 7 also allows Apple Watch to take cardio fitness measurements as users walk throughout the day, irrespective of tracking or workout activities.
Cardiorespiratory fitness, as measured by VO2 max, is the maximum amount of oxygen the body can use during exercise, and it can be increased through physical activity.
Apple Watch already estimates average and higher levels of VO2 max during vigorous outdoor walks, runs, or hikes.
