The “anti-stress” experts Dr. Egor Egorov and Nicole Franke-Gricksch have published a new book in which they also mention and test a number of apps. We are very pleased with the positive reviews of our apps HeartBreath HRV and BreathTuner HRV and would like to thank you for the kind support.
You can find out more about the book and the authors on the book’s homepage.
6 breaths and never be stressed again
