Installing Heart Fitness app will allow you to measure your heart rate at anytime using your iPhone. All you need to do is to place the tip of your index finger on the camera lens when you use the app. It will monitor your heart rate through iPhoneâs camera and LED light as your heart pumps blood through your finger. A reddish hue will appear when the LED light shines through your finger and the camera will sense the pulsation to give an accurate measure of your heart rate.
