Having too low a heart frequency after being inactive for 10 minutes could mean your heart isn’t pumping enough blood to your body, which in turn might point to bigger issues. Here’s how to toggle on the potentially life-saving low heart rate notifications on your Apple Watch.
Not only does an enhanced Digital Crown in the new Apple Watch Series 4 provide subtle haptic feedback when turned, it now doubles as a sophisticated electrical heart sensor that can take reach electrocardiograms of your heart.
Apple’s Health Records feature has expanded from a dozen launch partners to almost 80 health system participants, including hundreds of hospitals and clinics that make this feature available to their iPhone-toting patients.
Apple Watch can alert you to start the right workout when it looks like you’re training and will even remind you to end the session if you forget. In case you don’t really need this handy auto-workout detection capability, disabling it will help prolong the watch’s battery life.
