Access a healthy and high-performance state called heart coherence, where your heart and brain are in sync — this helps you prevent or reduce stress, anxiety, and overwhelm, improve health and performance, and clear your thinking for more effective choices.
Use real-time heart rhythm coherence biofeedback and evidence-based techniques to live a healthier, happier life.
Learn to elevate your emotional state in the moment and become aware
of and release accumulated stress so you feel better and think more clearly.
Backed by 30 years of pioneering heart-brain research, the
Inner Balance Coherence Plus measures and translates your heart rhythm patterns (HRV) into
real-time coherence scores.
This trains you to get your heart and brain in sync, which prevents and reduces stress, anxiety,
and overwhelm, improves health and performance, and clears
your thinking for more effective choices.
With just a few minutes of daily practice, heart coherence becomes easily
accessible for more balanced, effective, and healthy living. Over time, you'll be equipped with a
skill set that you can apply, even without the app, in all aspects of your life.
The Science Behind the Inner Balance Coherence Plus
Our heart rate is always changing, creating a pattern. Heart rhythm patterns, also called heart rate variability (HRV), are a powerful window into our health and emotional wellness.
When we are out of sync (stressed, frustrated, anxious, etc.), our heart rhythm patterns are jagged and chaotic.
When we are in sync (composed, easeful, grateful, etc.), our heart rhythm patterns are smooth sine waves.
We can learn to change our heart rhythm patterns to change how we feel and perform.
Inner Balance Coherence Plus translates your heart rhythm patterns into a real-time coherence score that you can use to build your heart coherence.

How the Inner Balance Coherence Plus Sensor Works
HRV biofeedback to decode the language of your heart
The Inner Balance Coherence Plus uses professional-grade photodetectors to measure your pulse wave 500 times a second.
This data is then translated into highly accurate HRV, which reflects how your heart rate changes over time. HRV offers a powerful window into the quality of communication between the heart and brain, which directly impacts how we feel and perform.
Our proprietary algorithm then translates your heart rate data and HRV patterns into a real-time score that updates every 5 seconds.
This measurement helps you understand which thoughts, emotions, attitudes, or techniques increase or decrease your heart coherence — so you can train yourself to access this highly beneficial state.
Hours of video and audio content designed to activate meaningful change throughout your life.
The HeartMath® app is much more than coherence measurement. Expert-led content included in the HeartMath companion app helps you build a coherence skill set through courses, learning journeys, and practices designed to help you activate meaningful change throughout your life — everything from powering up your day with more energy, effective decision-making, getting along with others, releasing the day's tensions, better sleep, and much more.

Inner Balance™ Coherence Plus Sensor Consumer FAQs
How can the Inner Balance Coherence Plus sensor and HeartMath app help me?
The Inner Balance Coherence Plus sensor and HeartMath app help train you in heart coherence — an optimal physiological state where your heart and brain are in sync. Increasing your heart coherence has been shown to reduce stress, overwhelm, and anxiety and enhance clear thinking and more effective choices.
Is HeartMath based on science?
Yes. For 30 years, HeartMath Institute has been at the forefront of heart-brain research. Over 500 independent research papers have been published on heart coherence and its associated benefits, which include key health, wellness, and effectiveness indicators. To learn more about the science of HeartMath, click here.
What are the key benefits of using the Inner Balance Coherence Plus and HeartMath app?
How long does it take to see or feel the benefits of using the Inner Balance Coherence Plus and HeartMath app?
There are several ways you'll experience benefits. After just a few minutes of heart coherence practice, people often report feeling more balanced and less stressed. Studies with over 14,000 people have shown improvements in mental and emotional wellness in just 6 to 9 weeks of practice (we suggest 10 minutes a day). Heart coherence practice has a carry-over effect, providing more ease and flow throughout your day.
How long should I practice with the Inner Balance Coherence Plus and HeartMath app?
Any practice is helpful, but we suggest creating a regular practice of 10 minutes a day to increase your coherence. If you miss a day, no problem; just pick up where you left off.
Is the Inner Balance Coherence Plus wearable? Do I have to wear it all the time?
The Inner Balance Coherence Plus and HeartMath app are designed to be a training device. You do not wear the sensor all the time; you only attach the ear sensor when you want to train with coherence measurement. We recommend 10 minutes a day.
What makes the Inner Balance Coherence Plus and HeartMath app different and unique?

What is heart rate variability (HRV)?
The naturally occurring beat-to-beat variation in heart rate is called heart rate variability (HRV). HRV is an important indicator of overall health and wellness. The Inner Balance Coherence Plus sensor with the HeartMath app analyzes and displays your HRV pattern and translates it into a real-time coherence score, reflecting the synchronization between your heart and brain. Regular practice to increase your coherence is associated with many health, wellness, and effectiveness benefits.
Why do I need to use a sensor with HeartMath apps?
In order to measure your HRV, you need a sensor to capture your heart rhythm and analyze your coherence in real time.
Can the Inner Balance Coherence Plus work with other non-HeartMath HRV apps?
The Inner Balance Coherence Plus sensor works with any HRV app with the standard profile. However, we do not guarantee that the HeartMath technology will work with all third-party products.
Does the Inner Balance Coherence Plus sensor work on smartwatches?
The Inner Balance Coherence Plus sensor does not work on smartwatches.
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.
