Meet Cardiio, a completely new way to check your pulse. Just hold your phone or tablet in front of you and get your heart rate accurately measured in seconds. It's heart rate monitoring, reinvented.

Born at MIT, Cardiio uses your device's front camera to analyze the amount of light reflected off your face to accurately measure your heart rate. Track your progress and improve fitness. Plus, Cardiio lets you gain insight into what your heart rate numbers mean as your resting heart rate is an important indicator of general health, fitness and longevity.

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 front camera can track these tiny variations in light that are invisible to the naked eye to calculate your heart rate.


ACCURACY
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.

IMPORTANCE OF TRACKING YOUR HEART RATE
Your resting heart rate is an important indicator of general health, fitness and longevity.
• Although increasing your heart rate during exercise is good, it is generally better and healthier to have a lower resting heart rate.
• A lower resting heart rate means that your heart is stronger and can work more efficiently.
• A slower heart rate also generally indicates aerobic fitness.
