Discover a calmer self for a longer life 

Stress is inevitable – stress overload and burnout is not. If we allow stress to build up in our bodies without finding a healthy way to manage it, it can have serious long-term consequences on our health. 

The good news is, there are simple ways to reduce your stress, even as you navigate our hectic modern world. iheart HRV gives you real-time insights into your stress response and offers a starting place to develop healthier lifestyle habits that increase your resilience and help you get in touch with your calmest self.

How It Works

1. Measures your Heart Rate Variability (HRV)

The iHeart HRV app analyzes your heart rate variability (HRV), a well-documented measure of your body’s stress response. You’ll be able to watch your heart rate and breathing in real-time. 

2. Calculates your stress response.

Once it’s done analyzing, iheart HRV will assign you a score on a 1-100 scale, with 1 demonstrating maximum stress and 100 being the most relaxed possible. 

3. Provides instant biofeedback

Unlike our other apps, iheart HRV results can be altered moment-to-moment based on your heart rate and breathing, giving you the opportunity to practice and visualize the effects of relaxation techniques.

Measure the impact of stress-reduction habits

The iheart HRV app is not only useful in giving you an idea of how much stress you’re holding in your body today, but can be a fantastic learning tool to help you practice relaxation techniques. 

As you take your readings and watch the line fluctuate on the graph, you can see how your heart rate and oxygen saturation are affected by the way you breathe and even the thoughts running through your mind. We encourage you to use this as an opportunity to learn how your body reacts to physical manifestations of stress, and use it to practice stress-reducing techniques like diaphragmatic breathing and positive thinking. The applications are endless.
