The HeartMath Inner Balance™ Trainer is an innovative approach to improving wellness through training, education and self-monitoring. Inner Balance shows you your heart rhythm pattern (HRV) and a breathing pacer to go along with your heart rhythms, training you how to change your heart rhythm pattern to a healthier, coherent state. Inner Balance Trainer works exclusively with the one of a kind HeartMath iOS connector that attaches to your iPhone or iPad and your earlobe and feeds your heart rhythms into the app. No technology on the market today tracks at the high level of the HeartMath iOS connector.
