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.


Elevate your mental and emotional wellness

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 skillset 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

ear sensor

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


Feeling Appreciative

ear sensor

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

ear sensor

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.

Requires Bluetooth 4.0 or higher

This product is designed for use with Android v9.0 and above

Requires iOS 16.0 or above. Works with iPhone 8 and newer, iPad OS 15 generation and newer.
*Inner Balance Bluetooth uses BT4.0 (BLE–Bluetooth Low Energy) which works at an output power range of 0.5 milliwatts (mW) or less — this is significantly lower than mobile phones which typically have output levels between 250 mW and 2000 mW. The tiny Bluetooth emitter is in the module that attaches to your garment, not in the ear sensor. Inner Balance Bluetooth is compliant with applicable FCC tests.

Frequently Asked Questions

The Inner Balance™ app takes the information from the Inner Balance pulse sensor and translates it into real-time feedback on your Heart Rate Variability (HRV). In the App, you can also track results, and utilize the library of guided Techniques and Exercises. It is an innovative approach to improving wellness through training, education and self-monitoring. The app helps you track your progress in the journey of learning how to manage stress, shift your moods and create a more positive outlook on life.

Most people choose our Inner Balance Bluetooth sensor because it works wirelessly with both Android and iOS mobile phones and tablets. We have wired solutions for iOs (Lightning) and Android (USB-C)

Both products use the same Coherence measurement algorithm. The Inner Balance is designed for mobile phones and tablets. The emWave2 is a stand-alone device that operates without a mobile phone or computer.

Both products use the same Coherence measurement algorithm. The Inner Balance is designed for mobile phones and tablets. The emWave Pro is designed to work with desktop computers and allows you to create multiple user profiles and track the progress of each individually, which is a feature that health professionals use.

We recommend using the Inner Balance for 10 minutes a day for 6 weeks to reset your baseline response to stress. The Inner Balance is also designed to train you how to get into coherence without the App so that you can do this at any time during the day.

Once you have the Inner Balance™ sensor, download the Inner Balance app, pair your sensor with the app and start a session to see your real-time feedback within moments.

Coherence is a state of internal synchronization between the heart and the brain. Often, people experience coherence as a sense of inner calm and balance, an increased focus, while others experience coherence as a more composed state.

HeartMath Techniques and the Inner Balance are designed to help you shift your emotional state in the moment. You will likely feel better after your very first session. With regular practice, you will start to reset your baseline response to stress which will leave you with more energy throughout the day. You should start to see this type of impact after using the Inner Balance for 6 weeks.

No, only when you are running a live session.

No – but it helps! HeartMath Techniques are easy to learn and use. We encourage everyone to use these techniques throughout their day.
