- The gyroscope in the Apple Watch Series 4 helps to detect a fall or a slip in real time. If the user falls, the smart watch suggests to call the emergency services.
- The redesigned heart sensor allows to do the electrocardiogram test with the smartwatch on the wrist by placing a finger on the Digital Crown. The results are displayed in the app on the tethered iOS device.
- The Apple Watch Series 4 can also monitor the heart rhythm in the background and send alert notifications if it’s too fast or too slow. The smartwatch is approved by FDA and American cardiologists.
