Apple Watch Series 4 features a complete redesign with new ways to help track your health and activity, and to stay connected. A larger display with curved corners makes it easier to view and interact with important information on the go. The reengineered Digital Crown delivers haptic feedback while you scroll, and a 50 percent louder speaker improves all voice interactions. Three new heart health features—including the first direct-to-consumer electrocardiogram (ECG) app—and a new fall detection feature make Apple Watch a more intelligent guardian for your health. With its updated design, faster performance and watchOS 5, Apple Watch Series 4 helps you stay active, healthy, and connected.
