Vitality can read changes in a person’s blood pressure using an iPhone’s camera and graphics processing power. The goal is to replace blood pressure cuffs to become the most accurate method of measuring changes in blood pressure and eventually other changes in the cardiovascular system.

The app is still in beta testing and is expected to complete an official commercial rollout in 2019.

The technology relies on a technique called photoplethysmography. By turning on the light from a phone’s flash and placing a person’s index finger over the camera on the back of the phone, the light illuminates the blood vessels in the fingertip and the camera captures changes in intensity as blood flows through the vessels with each heartbeat.
