The Inner Balance Coherence Plus


The New HeartMath® App

HeartMath App

Includes free lifetime subscription to the HeartMath App (regular $79/year).

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.

Inner Balance Coherence Plus

Feeling Stressed

Heart Rate Variability (HRV)

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

Feeling Grateful

Heart Rate Variability (HRV)

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.

Lower Score

Lower Score / Out of Sync

It (HeartMath tech) has helped me to gain focus, improve productivity, elevate mood, and improve my communication and connectedness with my colleagues, clients, and family.

A. Showalter Colorado Springs, CO

HeartMath techniques and meditations have allowed me to unlock access to portions of my true self I never knew existed. The day-to-day ’grind’ of life no longer feels like a grind but a gift that I get to experience. Amazing how the physical situation hasn’t changed, only the internal situation, and happiness flows with it.

J. Oldach Lawndale, CA

Ten years ago, I was running a business that I hated. I was stressed out, miserable to be around and desperate for a life change. I was hoping for a way out of the business and something quick in regards to vocational change. Instead, it was a small, simple device that helped me see a different way. … Slowly but most surely, I found that my response to stressful situation, employees, difficult jobs began to changed. In time, I realized that I could make the transformation in my life simply by moving in a different direction. …Learning to center our direction and purpose on the heart is a gentle but true life changer.
