Apple Watch Series 4: Beautifully redesigned with breakthrough communication, fitness and health capabilities
Cupertino, California — Apple introduced a redesigned Apple Series 4 watch and re-engineered to help users stay connected, be more active and manage their health in powerful new ways. While retaining the original iconic design, the fourth-generation Apple Watch has been refined, combining new hardware and software enhancements into a genuinely singular, unified form. The stunning display is over 30 percent larger and seamlessly integrates into the thinner, smaller case, while the new interface provides more information with richer detail. Apple Watch Series 4 with watchOS 5 brings advanced activity and communications features, along with revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls, and an electrical heart rate sensor that can take an electrocardiogram (ECG) using the new ECG app,1 which has been granted a De Novo classification by the FDA.
With watchOS 5, Apple Watch intermittently analyzes heart rhythms in the background and sends a notification if an irregular heart rhythm such as AFib is detected.3 It can also alert the user if the heart rate exceeds or falls below a specified threshold.
Fall detection utilizes a next-generation accelerometer and gyroscope, which measures up to 32 g-forces, along with custom algorithms to identify when hard falls occur. By analyzing wrist trajectory and impact acceleration, Apple Watch sends the user an alert after a fall, which can be dismissed or used to initiate a call to emergency services. If Apple Watch senses immobility for 60 seconds after the notification, it will automatically call emergency services and send a message along with location to emergency contacts.
With watchOS 5, Apple Watch becomes an even better fitness and workout companion. Activity competitions allow users to challenge other Apple Watch wearers, automatic workout detection provides an alert to start a workout while giving retroactive credit, and Yoga and Hiking are new dedicated workout types that accurately track active calories burned and exercise minutes earned. Running enthusiasts can take advantage of extended battery life — which is increased to six hours — for outdoor workouts and enjoy high-performance features, including cadence for indoor and outdoor runs, pace alerts for outdoor runs and rolling mile pace, which shows pace for the immediately preceding mile.
Customers can reach their friends with just a tap of the wrist with Walkie-Talkie, a watch-to-watch connection that is an entirely new way to communicate around the world over Wi-Fi or cellular.4 The Siri watch face is more predictive and proactive, offering shortcuts and actionable content from favorite third-party apps. watchOS 5 also lets users listen to their favorite podcasts on the go with Apple Podcasts on Apple Watch, and stream any podcast in the catalog by using Siri. With Apple Watch Series 4, enriched complications offer a more detailed view of helpful third-party apps like Dexcom, which allows for continuous glucose monitoring, or Streaks, which shows daily progress on tasks.
