BreatheSync uses scientific data from deep autonomic breathing research experiments to create an index based on age of the health of your autonomic nervous system. This is a good indicator of your inner wellbeing. While you are using Breathe Sync the app is taking measurements and comparing them to this data. The maths used is the same as the IQ system of measuring intelligence. 100 is average and most people will be between 70 - 130. Under 100 shows your WQ is below average and over 100 shows it above average. That said, in our experience, most people average under 100.
