The Apple Watch is an incredibly useful device for monitoring fitness and health. One of its most important sensors allows you to measure heart rate, providing relevant data on our heart health at all times.

When the heart beats, blood flow and green light absorption increase, allowing the number of beats per minute (BPM) to be accurately calculated.
In addition to the optical sensor, Apple Watch Series 4 and later models include an electrical sensor, which allows for more precise measurements using the Digital Crown and the back of the watch.
