The Inner Balance Coherence Plus is a device designed to enhance mental and emotional wellness by promoting heart-brain coherence. It measures heart rhythm patterns, also known as heart rate variability (HRV), to provide real-time coherence scores. This helps users synchronize their heart and brain, reducing stress, anxiety, and overwhelm, while improving health and cognitive performance.
The device uses professional-grade photodetectors to measure pulse waves, translating this data into accurate HRV readings. These readings reflect the quality of communication between the heart and brain, impacting emotional and physical well-being. By practicing coherence, users can improve emotional regulation, cognitive function, and resilience to stress.
The Inner Balance Coherence Plus includes a lifetime subscription to the HeartMath app, which offers expert-led content to build coherence skills. This includes courses and practices aimed at enhancing energy, decision-making, and emotional management. The device is compatible with both iOS and Android, connecting via Bluetooth or USB-C, and is designed for comfort and durability.

The evidence is not strong enough to support disease-treatment claims, and outcomes appear context-dependent.
