Apple's latest Watch can sense falls and heart irregularities
The current Watch 3 is already pretty health-centric, but Apple has taken it to a new level with its latest model. Thanks to a new electric heart sensor built into the backside, the Watch Series 4 can not only detect a low heart rate but also act as an electrocardiogram (ECG). That means it can sense a dangerous condition known as an atrial fibrillation and warn you to talk to your doctor. The Watch Series 4 has received clearance from the FDA and is the first over-the-counter ECG app offered directly to consumers, Apple claimed.
