While my elliptical does not factor in age, gender, weight, or height- it does track the resistance, time spent on machine, and the heart rate to give a general caloric burned output. However, this number is usually about half of what the SP app will give. For example, if I work out for 20mins on my machine it states that I burned 186 Kcals. But if I were to track that using the SP app, it states a caloric burn of 304 Kcal. (And my HR monitor gives a completely different number.)
I have been adjusting the time exercised when imputing my workouts to match the calories burned. Is this what others do? Does anyone else skew the time to get a more accurate calorie deficit? And since the time is showing a 12 min workout as opposed to a 20 min workout, do you adjust your workout time goals?
