Apple has again doubled down on health and fitness with a slate of new features for its Apple Watch. One of those in particular has even received approval from the FDA.

The world’s most valuable tech company announced upgraded functionality for its heart rate sensor that puts Apple in an entirely new category of medical-grade devices.

The Apple Watch sensor can now read a user’s electrocardiogram (ECG) and alert users when their heart rate is too low or too high and if they’re displaying signs of atrial fibrillation.
