*** This app requires bluetooth hardware to work. We are currently creating a list of suitable hardware devices. Because we are measuring precise HRV data the sampling frequency of the device as well as how the data is handle is crucial. We know it works very well with the polar chest strap and will be testing more and creating a comprehensive list. ***

Negative emotions don’t just feel bad, they are killing you…

The data is overwhelming showing your negative emotions are the highway to disease. Feeling anxious, angry, frustrated, overwhelmed and stressed breaks down your immune system so your body can’t fight back.

It starts with your breathing. Breathing is the fastest way to control your physiology. Coherent physiology melts away negative emotions.
Your physiology is like an orchestra. If you feel anxious the orchestra is out of tune. The most important instrument in your body’s orchestra is your Heart Rate Variability. If you get that in tune everything else follows.

Are you letting negative emotion ruin your life?

Studies in the US show 23% of women and 14% of men suffer from an anxiety disorder. Thousands more live in quiet desperation. Do you hide it from your family and friends?

Good. Needs tweaks

The app is well designed, but needs a few fixes. There doesn't seem to be a way to disable the screen lock, so every few minutes I need to tap the screen to keep it running. This is a huge oversight. It would be great to have some sounds for the breathing cycle and I would like to have a choice of colors. The blue is overly "baby-blue" and the colors when not in coherence are harsh reds.
Could be a great app with some updates.

Bluetooth Interface Good and Bad

I have the app loaded on my iPhone se and my iPad Pro 12.5 It works very well on the iPhone with my HeartMath Clip and my Polar H10, other than small print with low contrast, I could not be happier. I have used Heartmath, but I’m only interested in Heart Resonance and their screen is awfully busy with information I don’t need and sounds that are not helpful. I really appreciate the clean, simple screen on this app.

The downside comes with the iPad. I have no problem linking the Heartmath and H10 to the iPad for other apps, but this one gives me an error message about Bluetooth LE and will not link. I would really like to be able to use the larger screen.

A curiosity; after offer a lot of alternative timings it drops from 4.0 to 2.0 b.p.m. My resonance tests out well at 4.0, and is certainly easier to see here, but it would be nice to try 3.5 and 3.0. A very minor quibble.

Great product thank you!

I love this product. What would help me is if the Pla Audio when coherent would play! There's a problem on iOS 10.3.1 rn. When you click any of the audio options a blank screen tries pops up but then disappears. Would love the feature to work!
