Real-time feedback
Watch your heart rhythm and coherence change moment to moment as you breathe and settle — so you can feel what balance actually feels like.
The app is where your Inner Balance Coherence Plus sensor comes to life. Clip on the sensor, watch your heart rhythm in realtime, and follow short guided sessions that help you shift out of stress and back into balance — a calm you can actually see.
The app reads the rhythm of your heartbeat — your heart rate variability, or HRV — and turns it into a live picture of how your body is handling stress. The Inner Balance Coherence Plus sensor is what makes that reading precise.
Clip the sensor to your ear and the app shows your heart rhythm beat by beat, with the accuracy the HeartMath method was studied on. You see the shift as it happens — not a score after the fact. See the sensor →

The HeartMath method draws on research from the HeartMath Institute — an independent nonprofit that has pioneered heart-rate-variability and heart-brain research since 1991. HeartMath translates those peer-reviewed findings into the practical tools inside the app.
