How It Works Over the past several years, research studies have been conducted involving more than 100,000 people wearing smart watches and the results were very positive, showing strong levels of accuracy in the ability to predict illness from health data that was recorded by the wearables. This app integrates with Apple Health and uses a multitude of data that is provided by your wearable everyday such as Active Energy, Body Temperature, Heart Rate, Heart Rate Variability, Oxygen Saturation, Resting Energy, Steps, Resting Heart Rate, Sleep Data and more. The SickPredict™ App calculates, in real-time, your personalized SickNumber™. The daily SickNumber™ ranges from 1-10 to help anticipate any upcoming changes in your health.
