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. Three new heart health features— including the first direct-to-consumer ECG (electrocardiogram) app and a new fall detection feature make Apple Watch a more intelligent guardian for your health. Cellular brings the power of Apple Watch anywhere—even when you’re away from your phone—so you can make an important call, reply to a message, have a quick chat with Walkie-Talkie, and even stream Apple Podcasts. With its updated design, faster performance, and watchOS 5, Apple Watch Series 4 helps you stay active, healthy, and connected.
