How does the Pulsense device calculate the calories I've burned?

• The Pulsense device uses your body weight, activity, and heart rate to calculate the calories you've burned. Most other brands do not factor in your heart rate for the calculation. If you stop the Pulsense device from measuring your pulse rate, it will use your body weight and step count to calculate the calories you've burned.
  

  You can see how many calories you've burned in the PULSENSE View app, the web portal, or on the PS-500's LCD.
