Want to find purpose in your life? Sleep better, eat better, lose weight, increase energy, decrease stress? Well, now there’s an app for that. JOOL Health is a new Ann Arbor-based digital health solution company led by CEO and founder Vic Strecher, professor at the School of Public Health and director for Innovation and Social Entrepreneurship. JOOL integrates the science of purpose, advanced mobile technology, and big data analytics to help employers, health plans, and health systems improve their populations’ health engagement and overall well-being through sustainable behavior change. The app’s predictive modeling is based on several years of research by Strecher. Currently, JOOL is licensed to employers, health plans, and other care providers, but the company will consider making it available for individuals in 2017. The app is used by more than 3,000 individuals, with more signing on each month.
