Developed to work for more people in real-world conditions

Thanks to increasingly powerful sensors and advances in computer vision, these features let you use your smartphone’s camera to track tiny physical signals at the pixel level — like chest movements to measure your respiratory rate and subtle changes in the color of your fingers for your heart rate.

We developed both features — and completed initial clinical studies to validate them — so they work in a variety of real-world conditions and for as many people as possible. For example, since our heart rate algorithm relies on approximating blood flow from color changes in someone’s fingertip, it has to account for factors such as lighting, skin tone, age and more in order to work for everyone.
