Cardiio’s technology is based on cutting-edge research and science conducted at the MIT Media Lab. Every time your heart beats, more blood rushes through the vessels in your face, causing them to expand. The increase in blood volume absorbs more light, resulting in a decrease in the amount of light reflected from your face. Using sophisticated software, your iPhone's camera can track these tiny variations in light that are invisible to the naked eye to calculate your heart rate.

• Look ahead and hold your phone 6 inches in front of your face
• Be in a well-lit area so your face is well illuminated.
• Make sure your face is clearly visible (e.g. no long hair covering your forehead etc.) so that it can be easily detected.
• Don’t have a bright background behind you (backlight) - it makes your face appear dark in contrast.
• Fold one arm across your chest and rest the other arm that’s holding your phone against it to provide support and reduce motion of the phone during measurement.
• Hold your phone steady and keep still during the measurement.
