Hi there,

I've been trying to use my iPhone 5s to track calories burned through exercise on a treadmill, but the amount of calories the phone is reporting is about 5x higher than what the treadmill is reporting.

On a 30 min, light paced/short run exercise, the treadmill reported 150 cal whereas the iPhone reported 810 cal burned.

Which one should I trust?

Thanks in advance.

    If those are the only 2 choices, go with the treadmill. 810 calories in 30 minutes is way out of line.

    My treadmill will give me numbers in the 800's but it takes 65 minutes with 10 of it jogging. For a 257 lb man that is.

    are both devices measuring in calories or is one in calories and one in kilojoules?

    My fitness app glitches constantly if I am tracking indoors, and it will say I've gone .5 mile and burned nearly 80 calories in 4 minutes walking at a normal pace. I trust fitness apps for tracking distances outside and timing me; not for their cal counts. I compare them to the fitness database and will trust a machine that is physically tracking my HR over an app any day.

    My advice is that neither will be accurate. I've found a site that I think is decent. They make allowances for incline, which makes a huge difference, and even give you the equation they use in the calculations, so you can see how they arrive at the figure they give you. The only thing I don't like is that I'd prefer to give the rate and time at which I'm exercising, and -- dammit -- they ask you to enter time and distance. Since my treadmill only gives distances in tenths of a mile, I have to use 8th grade algebra to figure my distance accurately enough to satisfy my obsessive-compulsive nature (rate x time = distance). shapesense.com/fitness-exercise/calculators/walking-calorie-burn-calculator.aspx
