emWave2 vs. Inner Balance Coherence Plus: Which one is right for me?

Overview

HeartMath offers two distinct portable devices for coherence training: the emWave2 and the Inner Balance Coherence Plus. While both devices use the exact same patented sensor technology and algorithm to measure Heart Rate Variability (HRV) and Coherence, they offer very different user experiences.

 

 

This guide will help you decide which device fits your lifestyle and technical preferences.

1. emWave2 (The Standalone Handheld)

The emWave2 is a classic, all-in-one handheld device. It is designed for users who want to practice without being tethered to a smartphone or tablet.

 

 

  • How it works: It has a built-in "Breath Pacer" (lights that move up and down) and a sensor that plugs directly into the device. You do not need an app or internet connection to run a session.

     

     

  • Feedback: Simple LED lights indicate your Coherence Level (Red, Blue, Green). It also has audio feedback.

  • Computer Connection: You can plug it into a computer (Windows/Mac) via USB to upload your sessions to the emWave Pro software (included) for deeper analysis.

     

     

  • Best For:

    • People who want to disconnect from their phones.

    • Users who prefer simple, tactile buttons and lights over touchscreens.

    • Clinics or schools where phone use is restricted.

2. Inner Balance Coherence Plus (The App-Based Sensor)

The Inner Balance Coherence Plus is our most modern sensor, designed to turn your smartphone or tablet into a powerful biofeedback trainer.

 

 

  • How it works: The sensor connects to your mobile device via Bluetooth (wireless) or USB-C (wired). You must use the free Inner Balance App to see your data.

  • Feedback: Rich, real-time visuals on your phone screen. You get detailed graphs, guided meditation audio, "mood" tracking, and immediate access to your history on HeartCloud.

  • Computer Connection: It can also connect to emWave Pro on a desktop via the included USB-C cable.

     

     

  • Best For:

    • Users who love visual data and tracking progress over time.

    • People who want guided audio meditations and "Journeys."

    • Those with modern smartphones (iPhone 15+, Android) who want a future-proof device.
