You can choose between two methods, the auto mode, which will use your phone camera to detect the blood flow, it works exactly like any oxiometer.
To get started just cover the camera and the phone LED with your fingertip without applying any pressure(as the blood flow wont be visible), and press start. In about 10-20 seconds you will have your heart rate displayed on the screen. Simple as that.
Or you can choose the manual mode, in case the first method is not working for you. Just press the green start button and start counting your pulse. When you have counted 10-20 beats, click the stop button and enter the number. HeartBeats will calculate your heart rate and store the rate in its history. You can also use it to store your family heart rate history. It is that simple!
And it is free !
Disclaimer: The new beat detection algorithm only works with devices that have LED, which is an iPhone 4, iPhone 4S and an iPhone 5 or any other news models.
