A pocket-sized heart rate variability coach that plugs into your iPhone for guided coherence sessions. The HeartMath Inner Balance tracks your HRV in real time while a paired app walks you through breathing exercises that support stress resilience and calm focus. A practical tool for daily on-the-go stress training.

The Inner Balance Trainer analyzes and displays your heart rhythm while measuring Heart Rate Variability (HRV) — a window into the quality of communication between heart and brain. The wired ear sensor connects via Apple Lightning port and reads your pulse with a medical-grade photodetector at a 125 Hz sample rate, so the app can visualize coherence in real time and guide you toward a calmer, more resilient physiological state.

An unparalleled window into your emotional wellbeing

Sometimes, all we need is a little feedback to make positive changes within ourselves. Imagine if that feedback could come straight from your own heart. Well, now it can.

The Inner Balance™ wired sensor and app teach you how to shift from stress and frustration to balance and resilience with real-time feedback, based on your own heart rhythm. This wired sensor connects to your iPhone or iPad that is equipped with the Apple Lightning port.

The Inner Balance™ Trainer is based on years of scientific research and is designed to teach you how to shift your emotional state in the moment – so you feel better and think more clearly.

When we’re stressed, we feel poorly, and our brain function and creative thinking become impaired.

We might overlook or forget important details, overreact to small stuff, say things we regret, get overwhelmed, have trouble sleeping or feel exhausted and drained. But it doesn’t have to be this way!

Learn how to synchronize your heart, mind, and body to reset your composure and inner clarity, calm reactive emotions, and neutralize stress. This creates an inner state called coherence.

With practice, you’ll feel calmer, more centered and focused – and enjoy a 'carryover effect' into your next activity. You will access more intuitive discernment to make better decisions.

This self-empowering technology uses heart rhythm feedback to tell you when you’re on the right track. A quick and easy 3-5 minute session a few times a day is enough to make a meaningful difference.

How the science of the Inner Balance works:

The Inner Balance Trainer technology analyzes and displays our heart rhythm while measuring Heart Rate Variability (HRV). This indicates how emotional states are affecting our nervous system. Our HRV offers a unique window into the quality of communication between the heart and brain, which directly impacts how we feel and perform.

The Heart Math Inner Balance technology trains us to self-generate a highly efficient physiological state called HRV coherence, which helps us increase emotional composure and clearer reasoning. Recommended by health professionals worldwide, HRV coherence training has been associated with many health and performance benefits.

A few minutes of daily coherence practice has been shown to reduce and prevent the negative effects of stress, such as overwhelm, fatigue and exhaustion, sleep disruption, anxiety and burnout.
