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

Which apps does the Inner Balance Coherence Plus sensor work with?
The Inner Balance Coherence Plus sensor works with the new HeartMath app (our most comprehensive app to date), the Inner Balance app (our previous app), and the Global Coherence app (where you can join with others to contribute your heart coherence points to the global field environment).
Where do I find the HeartMath app?
Please go to the Apple App Store or Google Play Store and search for HeartMath. Download and open the HeartMath app.
What does 500 Hz mean?
The Inner Balance Coherence Plus sensor measures your heart rate at 500 Hz, which means it measures your heart rate 500 times per second, ensuring the highest degree of HRV accuracy.
How does the Inner Balance Coherence Plus sensor measure more accurately?
In addition to measuring your heart rate 500 times a second (500 Hz), the Inner Balance Coherence Plus sensor is best-in-class and uses high-performance precision technology that can discriminate even the smallest changes in your HRV. It features an advanced photodetector that works effectively with all people and eliminates artifacts.

You can plug the sensor into Android mobile phones or tablets that have a USB-C port. Please note that the wired connection to the sensor will not work with Apple iOS devices (iPad or iPhone). You must use Bluetooth to connect the Inner Balance Coherence Plus sensor to Apple iOS devices.
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.
