The New HeartMath® App


Unlock a more joyful, peaceful, and confident you!
HRV biofeedback to help you access a healthy and high performance state called heart coherence which balances your mind and emotions. This helps prevent stress and clears your thinking for more effective choices.
Measuring HRV & Coherence
Our heart rate is always changing, creating a pattern. Heart rhythm patterns, based on our “heart rate variability” (HRV), are a powerful window into our health and emotional wellness.

Feeling Stressed
When we are out of sync (stressed, frustrated, anxious etc.),our heart rhythm patterns are jagged and chaotic.

Feeling Grateful
When we are in sync (composed, easeful, grateful, etc.),our heart rhythm patterns look like smooth sine waves.

We can learn to change our heart rhythm patterns to change how we feel and perform.
The HeartMath app translates your heart rhythm patterns into a real-time coherence score that you can use to build your heart coherence.

What is heart coherence?
HeartMath Institute’s pioneering research defines heart coherence as the state that occurs when the naturally occurring, beat-to-beat changes in heart rate, or heart rate variability (HRV), become more ordered and regular, creating what’s called a coherent waveform. In heart coherence, many of the body’s systems, such as breathing, blood pressure, hormonal response, brain wave, and heart rhythms, become more in sync. HeartMath Institute research studies over thirty years have found that heart coherence not only facilitates physical processes but cognitive functions and emotional composure as well, leading to less stress and more resilience. Learn more here.
People learn to increase their heart coherence through heart-focusing techniques provided in the HeartMath app, which enable them to experience more uplifting positive emotions, such as gratitude, appreciation, care, and compassion, leading to calmness, clarity, and balance. HeartMath technology is designed to facilitate the state of heart coherence, measuring coherence in real time by analyzing heart rate variability and displaying the heart rhythm pattern. This allows the user to see how their thoughts and emotions can affect their heart rhythms, what coherence feels like, what increases it, and what may reduce it.
What does heart coherence feel like?
People often report feeling calm, balanced, and composed.
As people practice over time, this experience deepens and becomes easier to access. We call this creating a new coherence baseline. Practicing heart coherence has been shown to improve emotional and mental wellness, create more harmony in relationships and communications, and generate hope and confidence.
