MAGICAL, BUT NOT A TRICK
Cardiio’s technology is based on cutting-edge research and science conducted at the MIT Media Lab. The measurement principles are the same as clinical pulse oximeters. 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.
Studies have shown that our heart rate measurements are within 3 bpm of a clinical pulse oximeter when performed at rest in a well-lit environment (Poh et al., Optics Express 2010, Poh et al., IEEE Trans Biomed Eng 2011).
**IMPORTANT TIPS FOR BEST ACCURACY
• 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.
