Learn how smartwatches measure heart rate and the accuracy of heart rate monitoring in wearables. Understand the technology behind heart rate sensors and their impact on fitness tracking.
One feature that stands out is heart rate monitoring, which displays heart rate in real-time to display the result in BPM or beats per minute. Here’s a look at what is the meaning of BPM in a smartwatch, how a smartwatch measures heart rate in BPM, and why real-time heart rate monitoring is important.
Learn how heart rate monitors actually work, from optical wrist sensors to chest straps, and what to know about accuracy and heart rate zones.
Understand your smartwatch health data. Learn what heart rate, SpO2, and HRV mean, how composite scores work, and when to trust your readings.
Beyond step counting: understand how smartwatch sensors like PPG and ECG measure your heart rate, blood oxygen, and detect AFib.
Heart rate monitors measure how fast your heart is pumping in beats per minute (bpm). They’re usually small and wearable as a watch, an arm band or a ring, allowing you to track your heart rate all day or even at night. While they’re often reliable and convenient, they’re no substitute for check-ups and tests from a healthcare provider.
