Looking at the screen IS IMPORTANT!
I just got back from the AAPB conference (American Association for Psychophysiology and Biofeedback) where I learned about this fantastic app. During the presentation where it was mentioned (HRV for treatment of concussion) the researcher mentioned that subjects DID NOT IMPROVE significantly if they DID NOT LOOK AT THE SCREEN while breathing. Go figure. Next, finding your resonant frequency is quite important. This app will start you at a ‘best guess’ based on your gender and height. But to really know you’d have to measure your heart rate variability (HRV) and find the breathing pace which maximizes your HRV (the amount/range your heart rate goes up with inhalation and down with exhalation). So if you could figure out how to watch this paced breathing app while using something like the Camera Heart Rate Variability app you could objectively determine your resonant breathing rate. Also, you need to have a regular practice (like exercise) to continue to experience the benefits). Go for it, it may just save your life someday - better HRV is associated with increased survival after heart attack.
