What should I do if Apple Watch's heart rate measurement is not accurate?

Hello! If you think Apple Watch's heart rate measurement is inaccurate, you can adjust it as follows:

1, wear the Apple Watch strap tightly, so that the back of the watch is close to the wrist (especially when exercising);

2, Apple Watch should be worn on the back of the wrist, not in the direction of the palm;

3. When measuring the heartbeat, you can make the Apple Watch in a horizontal position, so the measurement will be more accurate;

4. Don't have tattoos on the back of 4.Apple Watch, which will interfere with heart rate measurement;

5. After all, Apple Watch is not a professional heart rate measuring device. It is normal to have a small amount of error. The point is to look at the average heart rate over a period of time. As long as the average heart rate is normal, there is no problem.
