How Apps can Measure Heart Rate?

Similarly to the heart rate trackers built into most fitness wearables, apps on your phone can measure your heart rate by detecting changes in blood volume below the skin’s surface – a practice called Photoplethysmography.

Every time your heart beats, the amount of blood that reaches the capillaries in fingers and face swells and then recedes. Because blood absorbs light, apps are able to capture this flow by using the flash of our phone’s camera to illuminate the skin and create a reflection.
