I see a field for calories but I gather there is no estimated calculation of calories expended based on age, weight, exercise type....etc as there is in some other programs. I know this is only a rough way of doing it but it would be somewhat helpful. In any event, is there a way to manually enter the amount of calories used?
You can't manually enter calories on your device. What device are you using? Some of the newer ones use a more elaborate method for calculating calories, using Firstbeat Technologies.
