Inner Balance™ Coherence Plus - Bluetooth Sensor

A Bluetooth heart rate variability sensor for the HeartMath Inner Balance Coherence Plus app. Tracks HRV in real time and guides you through interactive breathing sessions that train coherence and stress resilience. Cordless, rechargeable, and pairs with both iOS and Android.

$249.00

Bluetooth (this product)

Wireless BLE connection — works across iOS and Android devices, no cable. Same Inner Balance app experience.

Lightning (wired)

Direct cable to Apple Lightning port — wired Apple-only version of the sensor.

The Inner Balance Bluetooth ear sensor measures Heart Rate Variability (HRV) — the moment-to-moment variation in heartbeat intervals that reflects the quality of communication between heart and brain. The app trains you to self-generate a state called HRV coherence — a few minutes of daily practice has been associated with reductions in stress, fatigue, sleep disruption, anxiety, and burnout. Uses BT4.0 BLE which works at output power of 0.5 mW or less — significantly lower than typical mobile phone output (250-2000 mW). The Bluetooth emitter is in the clip module that attaches to your garment, not in the ear sensor.

Inner Balance Coherence Plus is HeartMath's most advanced HRV biofeedback sensor and app — designed to help you access a calm, high-performance state known as heart coherence.

What is the difference between the Bluetooth and Lightning versions?

They use the same Inner Balance app experience — the difference is the connection method. Bluetooth is wireless and cross-platform, Lightning is wired and Apple-only.

How much EMF does the Bluetooth sensor emit?

It uses Bluetooth Low Energy at 0.5 mW or less — significantly lower than the 250-2000 mW typical of mobile phones.

How long should I practice?

A few minutes of daily coherence practice has been shown to reduce the negative effects of stress.

Is there additional content beyond the app?

Yes — a free online platform offers progress tracking, journaling, daily practice plans, awards, and additional training.
