To use Instant Heart Rate effectively, place your finger on your phone's camera to measure your resting heart rate. Be cautious not to press too hard, as this may alter blood circulation to your fingertip. For the most accurate measurements, use the app daily to track your heartbeat or pulse, tagging your heart rate after sleeping or during workouts to differentiate between resting and active heart rates.

According to the American Heart Association (AHA) and the Mayo Clinic, a normal resting heart rate ranges from 60 to 100 beats per minute (BPM). Your heart rate can be influenced by various factors, including stress, anxiety, depression, emotions, activity level, fitness level, body composition, and medication use. Monitoring your heart rate is a crucial gauge of heart health and cardiovascular fitness, with heart rate variability being an important measure of stress on your body.
