Discover the most accurate heart rate monitor with Instant Heart Rate, the leading app that tracks your heart beat, beats per minute (BPM), stress levels, and cardio health. This user-friendly app is the most accurate and easy-to-use heart rate monitor available, and it has been utilized in heart research at the University of California, San Francisco (UCSF).

With Instant Heart Rate, you can get your heart rate in less than 10 seconds, check your stress levels, and gain valuable insights into 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 status.

Boasting over 35 million users, this award-winning app has been featured in major publications such as CNN, The New York Times, Chicago Tribune, The Guardian, and many more. It is the #1 Heart Rate app in countries including the United States, Japan, United Kingdom, Australia, Germany, France, China, Russia, Canada, and beyond.

Instant Heart Rate is continuously rated as the world's best mobile heart rate measurement app and is trusted by Stanford's leading cardiologists for use in clinical trials. It allows you to 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.

Key features include:

• Accurate measurement of your heartbeat, BPM, and pulse zone
• PPG graph (similar to ECG/EKG/Cardiograph) to visualize every heart beat and BPM
• Cardio workout monitoring to optimize exercise and track progress pre- and post-workout, using heart rate as a cardiovascular measurement
• Heart rate training zones (Rest, Fat Burn, Cardio, and Peak)
• Google Fit support for heart rate and heartbeat data
• No need for heart rate or heartbeat straps
• Ability to share heart beat data

To use Instant Heart Rate accurately, place your finger on your phone's camera to show 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 to monitor your heartbeat or pulse, and tag your heart rate after sleeping or during workouts to differentiate between 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). 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 crucial for gauging your heart health and cardiovascular fitness, and heart rate variability is an important measure of stress on your body.
