Health IQ is the first comprehensive measure of just how health literate a person is. It is delivered as an app that tests your knowledge, skills, and experience. To create it we hired 35 notable experts: including 3 faculty members from Harvard Medical School, the head orthopedic surgeon for the US Olympic team, prominent Yogis, published dietitians, and more. They wrote 30,000 questions. We calibrated these questions with a panel of 750,000 people to find which health facts mattered the most. Today almost 1MM people have taken their Health IQ.
