New Inner Balance™ Coherence Plus Sensor and App: Includes Free Lifetime Access to the New HeartMath® App Learn More

Coherence Technology

Experience and Sustain Your Heart Coherence

Based on research conducted at HeartMath Institute over the last 33 years, we offer the emWave® and Inner Balance™ heart-rhythm coherence feedback devices (Coherence Tech).

Our Coherence Tech™ is designed to help you quickly self-generate a highly efficient physiological state called heart coherence. It measures your heart’s rhythmic activity using heart rate variability analysis. Coherence tech "tells you" when you’re actually in the physiological state of heart rhythm coherence rather than assuming you are.

Why Heart Coherence Training is so Effective

Getting into heart coherence with the technology for 5 minutes or more each day can help to reduce and prevent the negative effects of stress in pressured decisions, choices and interactions. People report feeling more centered, composed and calm from a carryover effect as they move through their day.

Observe your heart rhythm (HRV) which reflects your level of inner balance and your emotional state.

Use scientifically validated techniques to guide you to a state of higher Coherence.

Real-time Coherence feedback confirms when you’ve made the shift and trains you to sustain it.

Coherence Tech analyzes then displays your heart rhythm pattern, which reflects how emotional states are affecting the nervous system. This gives you a unique window into the quality of communication between your heart and brain, which directly impacts how you think, feel and perform.

Choose the Right Coherence Tech for You!

Each product provides the same Coherence tracking and training.
