Keep Your Heart In Check
One of the most important reasons to own an Apple Watch is to keep track of your heart health. You can monitor your heart rate while you’re sleeping, relaxing, or working out.
Your Apple Watch can also send notifications when your heart rate is too high or low, which has been a life-saving feature for many people.
Besides that, you can also track the rhythm of your heart with the ECG app and keep track of your Atrial Fibrillation (Afib) history.
