Life-saving selfie app tested by 8,500 people at Portsmouth hospital 'will benefit millions'

Researchers at Queen Alexandra Hospital in Cosham carried out a study on 8,585 patients and staff using the Lifelight app. Using a selfie taken on a smartphone, and the ambient light that bounces off the skin, the app carries out calculations and tells the user the resulting rates. Among the hundreds of people who took part in the Vision-D project, 1,295 were diagnosed with previously unidentified high blood pressure during what was the largest digital physiological study in history.
