1 Built-in Fall Detection

A truly innovative new feature for Cupertino’s flagship wearable, the Apple Watch Series 4 boasts a new Fall Detection feature, which Apple COO Jeff Williams described as being able to detect when you’ve taken a hard fall. Using a complex series of sensors and a powerful new 64-bit S4 CPU, the Apple Watch S4 would then trigger an alert, prior to automatically issuing an SOS to emergency services if said alert is ignored. The feature will also issue text or iMessage notifications to your registered emergency contacts informing that that help is needed.
