Apple on Wednesday introduced a new health-focused Apple Watch, called the Apple Watch Series 4, with a larger display and a thinner overall body. The Apple Watch Series 4 has a handful of new watch faces to take advantage of the increase in screen real estate, including one with photos of users’ contacts that can be tapped to quickly make a call. Another face is based on Apple’s Breathe app, which guides users through a deep breathing exercise.
Thanks to a new accelerometer and gyroscope, the new Apple Watch can tell if a wearer falls. Upon detecting a fall, it will ask if the user needs help. If the Apple Watch doesn’t detect any movement for one minute, it will automatically send your location to emergency responders.
Along similar health-minded lines, the Apple Watch Series 4 can tell if your heart rate drops too low, or if you have an irregular heartbeat that may suggest atrial fibrillation. The new Apple Watch also allows users to take an electrocardiogram, or ECG. A built-in app can then check the results for potential problems, as well as record the data for users to share with medical experts.
The Apple Watch Series 4 has 18-hour “all-day battery life.
