How to use Instant Heart Rate, the heartbeat counter, for accurate measurements?

Place your finger on the phone’s camera lens to display your resting heart rate.

Blood circulation to your fingertip may change if you press too hard against the camera lens.

How often should you use Instant Heart Rate?

For optimal accuracy, Instant Heart Rate should be used daily to track your heartbeat or pulse. It is recommended to tag your readings after sleeping or during workouts to distinguish between resting heart rate and exercise heart rate.

What constitutes a normal heart rate or heartbeat?

According to the American Heart Association (AHA) and the Mayo Clinic, a normal resting heart beat ranges from 60 to 100 beats per minute (BPM). Your heart rate can be influenced by stress, anxiety, depression, emotions, activity level, fitness level, body composition, and medication. Understanding your heart rate is vital for assessing heart health and cardiovascular metrics. Heart rate variability is also crucial for measuring the physical stress on your body.
