How the Apple Watch Became a Life-Saving Device

The Apple Watch has saved another life by detecting blood clots in the lungs, a condition that the watch doesn't officially detect. Meanwhile, a study shows that the Apple Watch can assist in predicting pain episodes for Sickle Cell disease sufferers. Apple has been trying to crack blood glucose measurements to help diabetics for years, and the company's largest customer, Rockley Photonics, specializes in sensors that read multiple blood signals without the use of medical equipment. The intended medical purposes of the Apple Watch could be just the beginning.
