Your heart rate is an important indicator of your health. A heart that beats too fast or too slow can be a symptom of a bigger problem and an important reminder to a doctor. But how can you track your heart rate and keep a history of it? That's where your Apple Watch can be useful.
The Apple Watch comes with a heart rate app that can track your current heart rate and display your resting frequency and rates during various exercises. The workout app can record and display your heart rate during and after exercise. If you have the new Apple Watch Series 4 you will receive low and high heart rate warnings while an ECG app comes later this year.
But if you have an older Apple Watch or additional heart statistics, you can also enhance the capabilities of your watch through third-party apps.
