Discover the most accurate heart rate monitor with Instant Heart Rate, the leading app for tracking your heartbeat, BPM, stress, and cardio health. Designed to be the most accurate and user-friendly heart rate app, it's even utilized in heart research at UCSF, demonstrating its reliability and effectiveness.

With Instant Heart Rate, you can measure your heart rate in less than 10 seconds, check your stress levels, and gain valuable insights into your health trends. You don't need a dedicated heart rate monitor; simply download the app and use your camera's flash to assess your well-being instantly.

Boasting over 35 million users, Instant Heart Rate has garnered widespread acclaim, being featured in renowned publications like CNN, The New York Times, Chicago Tribune, The Guardian, and many more. It's the #1 Heart Rate app in the United States, Japan, United Kingdom, Australia, Germany, France, China, Russia, Canada, and numerous other countries.

Continuously rated as the world's best mobile heart rate measurement app, Instant Heart Rate is trusted by leading cardiologists at Stanford for use in clinical trials. It accurately measures your pulse and heart beat zones during sleep or workouts, 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 heartbeat, BPM, or pulse zone
• PPG graph (similar to ECG/EKG/Cardiograph) to visualize every heartbeat and BPM
• Cardio workout monitoring to optimize exercise and track progress before and after workouts, using HR as a cardiovascular metric
• 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 measure your resting heart rate. Be mindful not to press too hard on the camera lens, as this can alter blood circulation to your fingertip. For the most accurate measurements, use the app daily, tagging your heart rate after sleeping or during workouts to distinguish between resting and active 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). Factors such as stress, anxiety, depression, emotions, activity level, fitness level, body composition, and medication use can affect heart rate. Understanding your heart rate is crucial as a heart-health gauge and cardiovascular metric, with heart rate variability being an important measure of stress on your body.
