HeartMath's Inner Balance is a system featuring a sensor and app that guides users to a state of "coherence" by synchronizing the heart, mind, and body. By monitoring your heart rate variability (HRV), the technology provides feedback through breathing exercises and other prompts to promote inner clarity, calm emotions, and reduce stress and overwhelm. Regular practice helps build resilience, improve focus, and create a more balanced emotional state, fostering feelings of happiness and confidence.
