With Kardia, you can practice heart rate variability (HRV) training through paced breathing. By breathing at a specific rate, around 5.5 cycles/min, your HRV increases and becomes regular. This state is known as cardiac coherence, or cardio-respiratory coherence. Many scientific studies have demonstrated that it has beneficial effects on stress and anxiety level, blood pressure, depression and sleep.

The best breathing rate is different for everyone. With Kardia, you can set very precisely the exercise frequency, so you will just need a few tries to find out the value that gives you the best results.

* Very soothing *

I find it very helpful with breath regulation and calming/centering. I appreciate the various options to speed up or slow down the circle’s speed and the ability to turn the vibration, sound, etc., on or off to optimize the experience. I have the free app and am considering trying the (paid) feature…

Simple and Effective

I love the simplicity of this app. I finally am able to commit to a daily practice and I really look forward to it. The vibration is my favorite because you don’t have to be looking at the screen. I close my eyes and focus simply on breathing.
