Check the Electrical Activity of Your Heart

Modern Apple Watches can also track the electrical activity inside your heart. Thanks to the ECG app, you can easily keep track of the electrical signals that affect your heart’s rhythm. 

While it’s not the same as actually going to the doctor, this app can help you determine if there’s an unusual activity in your heart. Many people have mentioned how this feature has helped them detect life-threatening heart conditions, so it might be a good idea to get an Apple Watch just because of this.

You’ll be able to use the ECG app on the Apple Watch Series 4 and newer models, excluding the Apple Watch SE lineup.
