Trusted by Stanford's leading cardiologists for clinical trials, Instant Heart Rate is hailed as the world's best mobile heart rate measurement app. It offers precise measurements of your pulse and heart beat zones without the need for heart rate straps, functioning akin to pulse oximeters by detecting changes in your finger to provide accurate readings.

With Instant Heart Rate, you can:

• Accurately measure your heartbeat, BPM, and pulse zone
• View detailed PPG graphs, similar to ECG/EKG/Cardiograph, to see every heartbeat and BPM
• Monitor cardio workouts to optimize exercise and track progress before and after workouts using heart rate as a cardiovascular metric
• Utilize heart rate training zones including Rest, Fat Burn, Cardio, and Peak
• Sync data with Google Fit to track heart rate and heartbeat

To use Instant Heart Rate effectively, place your finger on the phone's camera to measure your resting heart rate. Be mindful not to press too hard on the camera lens, as this could alter blood circulation to your fingertip. For the most accurate measurements, use the app daily, especially after sleeping or during workouts, to distinguish between your resting and workout heart rates.

Understanding your heart rate is crucial. The American Heart Association (AHA) and the Mayo Clinic state that a normal resting heart rate ranges from 60 to 100 beats per minute (BPM). Factors such as stress, anxiety, depression, emotions, activity level, fitness level, body composition, and medication can influence your heart rate. Monitoring your heart rate is a vital gauge of heart health and cardiovascular fitness, and heart rate variability offers insights into the stress your body experiences.
