Heart rate variability, or HRV, is an indicator of how your body responds to stress and recovery. Too much training or poor sleep can increase your stress and thus lower your HRV. With the most accurate heart rate measurement in a wearable, the Apple Watch Ultra 4 measures HRV every five minutes. And heart rate values are measured in the background every five seconds. More frequently than any other Apple Watch. And with the redesigned Heart Rate app and new complications for the watch face, you can easily keep an eye on all measurements at any time. 60x more frequent background heart rate measurements than the Ultra 3 24x more frequent background HRV measurements than the Ultra 3 Stay updated while running.
