Dr. Sumbul Desai’s job is to think creatively about the different ways that technology can improve health. As Vice President of Health at Apple, she starts with strong data from studies the company conducts with academic institutes, the American Heart Association, and the World Health Organization to understand which metrics give the best window into overall health. Apple received approval in 2024 to turn the iPhone into a professional-grade hearing test, and AirPods Pro 2 got the go-ahead to function as hearing aids with just a few in-app adjustments.
