The Science Behind Coherence

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

The 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.

HeartMath has been a pioneer in HRV research and self-regulation training for over 29 years. Over 250 independent peer-reviewed studies have been published on HeartMath technologies and methodologies.

What People are Saying

Inner Balance Bluetooth for Android or iOS (Apple) is rated 4.7 out of 5 by 88.
Rated 3 out of 5 by from New to this I'm having an issue getting the device to connect. It connects to Bluetooth but tells me I need the app, but I have the app. So I went to the app and it told me I need the Bluetooth connection. I don't understand what I'm doing wrong here.

Rated 5 out of 5 by from I am enjoying learning! At this time I cannot give a very qualified review. I've only been using the device for a week. So far I can say that it is easy to use. Linked to my phone very easily and is recording my meditation sessions quite well. I have been meditating for a few years now so its nice to see that for most of the time during my meditations sessions I am in heart/brain coherence. At least at the lower level so far! Lol See how things go as I try the higher levels. The only draw back I feel I should mention is that it ended up being quite pricey. I waited to purchase it on your black friday sale which did say me some money, but shipping to Canada was expensive and then they added another $40 duty. Which you did warn me could happen. I just wasnt expecting it to be quite that much! Otherwise, I am happy with my purchase and am looking forward to achieving new levels of peace and understanding with the feedback from the monitor. Thank you very much! P.S. thank you so much for all you do at Heartmath!

Rated 5 out of 5 by from Words of gratitude fail me.... I was introduced to the HeartMath Institute via a documentary and then a Life Coach. The benefits of using my Inner Balance monitor and app are immeasurable!! I am experiencing less stress, and sustained feeling of peace and gratitude throughout the day.....and I seem to have those feelings for longer periods throughout the day....every day now! Each time I take the 5-10 minutes per day (twice a day ideally)....I am so grateful and thankful that I did! There are days when I just don’t want to take the time....and THOSE are the days....when I know I really need to find my Inner Balance!! I’m so grateful to the folks at HeartMath and the community.....nothing but LOVE now:)

Rated 3 out of 5 by from Still working with it Although I have a fairly strong internet connection, it has been difficult to get the device connected via Bluetooth. So my experience with the device has been sporadic .
