Discover the pinnacle of heart rate monitoring with the most accurate and user-friendly heart rate app on the market. Instant Heart Rate is not only utilized in heart research at the prestigious University of California, San Francisco (UCSF), but it's also trusted by Stanford's leading cardiologists for use in clinical trials. In just under 10 seconds, you can get your heart rate, check your stress levels, and gain valuable insights and trends about your cardiovascular health.

No need for a dedicated heart rate monitor; simply download Instant Heart Rate and use your camera's flash to assess your health. With a staggering user base of over 35 million and numerous awards, it's no wonder the app has been featured in top publications such as CNN, The New York Times, Chicago Tribune, and The Guardian, to name a few.

Instant Heart Rate proudly holds the #1 position in the heart rate app category in the United States, Japan, United Kingdom, Australia, Germany, France, China, Russia, Canada, and many more countries. Continuously rated as the world's best mobile heart rate measurement app, it allows you to accurately measure your pulse and heart beat zone without the need for heart rate straps. Functioning similarly to pulse oximeters, it detects changes in your finger to provide precise heart beat measurements.

With Instant Heart Rate, you can:

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

To use Instant Heart Rate accurately, simply place your finger on your phone's camera to measure your resting heart rate. Be careful not to press too hard on the camera lens, as it might alter blood circulation to your fingertip. For the best results, use the app daily to measure your heartbeat or pulse, and consider tagging your heart rate after sleeping or during workouts to differentiate between resting and active heart rates.

A normal resting heart beat, according to the American Heart Association (AHA) and the Mayo Clinic, ranges from 60 to 100 beats per minute (BPM). Your heart rate can be influenced by factors such as stress, anxiety, depression, emotions, activity level, fitness level, body composition, and medication use. Understanding your heart rate is a vital heart-health gauge and a key cardiovascular metric, with heart rate variability being an important measure of stress on your body.
