It stands as the #1 Heart Rate app in the United States, Japan, United Kingdom, Australia, Germany, France, China, Russia, Canada, and beyond.

Continuously rated as the world's best mobile heart rate measurement app, Instant Heart Rate is also trusted by Stanford's leading cardiologists for use in clinical trials. Measure your pulse and heart beat zone accurately after sleeping or during workouts and training, without the need for heart rate straps. The app functions similarly to pulse oximeters, detecting changes in your finger to provide precise heart beat measurements.

With Instant Heart Rate, you can:

• Accurately measure your heartbeat, BPM, and pulse zone.
• View a PPG graph (similar to ECG/EKG/Cardiograph) to see every heartbeat and BPM.
• Monitor cardio workouts to optimize exercise and track progress pre- and post-workout, using HR as a cardiovascular measurement.
• Utilize heart rate training zones (Rest, Fat Burn, Cardio, and Peak).
• Sync with Google Fit to support heart rate and heartbeat data.
• Share your heart beat data with others.

To use Instant Heart Rate for accurate heartbeat measurement, simply place your finger on your phone's camera to display your resting heart rate. Be mindful not to press too hard on the camera lens, as this may alter blood circulation to your fingertip.

For the most accurate measurements, use Instant Heart Rate daily. It's recommended to tag your heart rate after sleeping or during workouts to differentiate between your resting and workout heart rates.

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 various factors including stress, anxiety, depression, emotions, activity level, fitness level, body composition, and medication use. Understanding your heart rate is crucial as it serves as an important gauge of heart health and cardiovascular fitness. Heart rate variability is also a significant indicator of stress on your body.
