• Simply cover the back camera with your finger to read your pulse
• See how your heart rate relates to your fitness and endurance
IMPROVE YOUR FITNESS:
• Built-in high-intensity circuit training program that only takes 7 minutes to complete
TRACK YOUR PERFORMANCE:
• Personal dashboard with history (daily, weekly and monthly)
• Edit, annotate, export your data (CSV)
Cardiio’s technology is based on technology licensed from MIT and originally developed at the MIT Media Lab. MIT has not endorsed Cardiio-Heart Rate Monitor or Cardiio, Inc.
Blood absorbs light. Every time your heart beats, the blood flow to your face and finger increases, causing more light to be absorbed. In between beats, less light is absorbed. By using your smartphone camera to capture tiny changes in reflected light from either your finger or face, Cardiio can calculate your heart rate.
**IMPORTANT TIPS FOR BEST RESULTS
• ALWAYS hold your phone steady, keep still, and don’t talk during a measurement.
• Make sure your fingers are not cold.
• Cover the entire back camera lightly with your finger; Don't press too hard to avoid restricting blood flow to your finger.
• Look straight ahead and hold your phone around 6 inches in front of your face
• Be in a well-lit area so your face is well illuminated, but don’t have a bright background behind you (backlit) as it makes your face appear dark in contrast.
• Make sure your face is clearly visible (e.g. no long hair covering your forehead etc.) so that it can be easily detected.
