The Apple Watch Series 4 is a smartwatch by Apple Inc.. It was released during the 2018 Apple Special Event held at the Steve Jobs Theater in California. It has received mostly positive reviews from critics.
The Apple Watch Series 4 features the Apple S4 dual-core processor, which Apple claims can deliver double the S3's performance. It also features 16GB of storage, a larger display compared to the Series 3, and a new electrical heart sensor that measures the potential difference between the wrist and a finger from the opposing hand into the S4 Module over 30 seconds. The ECG system has received clearance from the United States Food and Drug Administration, a first ever for a consumer device, and is supported by the American Heart Association. This device can also detect falls and will automatically contact emergency services unless the user cancels the outgoing call. The microphone was moved to the opposite side between the side button and the digital crown to improve call quality. Other changes include the digital crown incorporating haptic feedback with the Apple Haptic Engine and includes the new Apple-designed W3 wireless chip.
