Is anyone else using the UA Record app on the watch? I see a big difference in the calorie count recorded between this and the apple workout app. Wasn't sure if anyone else has experienced this as well. Did a basic 39 min long CrossFit workout that was counted as 493 calories. Next day did a similar one to compare using the apple workouts app and was recorded around 260 calories. Yes not the exact same workout but very close. I would like to believe the UA app but would rather use the more accurate app lol.

What was the Apple's total calories? Apple splits a workout into active calories and total calories, but they have errors in the split-out. My hunch is that the UA app is presenting total calories. For the sake of accuracy and consistency, it is better to use Apple's total calories for a workout.

The UA calorie calc gave you 12.6 calories/minute. This is a solid zone 3 workout. If that sounds about right, then the UA may be in the ballpark.

If you add another 50 calories to your AW number to account for BMR burn, then your total is on the order of 310. This is 7.9 calories/minute, which is a probably a strong Zone 2 or low Zone 3 workout effort.

All of these calorie estimation algorithms are imperfect, so part of of this is using your RPE along with comparisons to other calorie algorithms to find a place that seems reasonable.
 
In the end, all calorie counts are estimates. What matters is you are able to see how your activity level today is in comparison to your past activity history. If you had used the same app both days, you would be able to see what effect the slight differences in your exercise had on your energy expenditure -- that is, you'd know which one caused you to spend more calories, if any. But because you used different apps, you can't compare the two values.
 
I have been using a ton of different things to track calories and the only thing I found that was pretty resonable is when I would wear a chest strap and attach to my apple watch or other fitness bands.

Using Apple Health App I could run 4 miles in 31 minutes and burn about 350 calories
Using Under Amour App I could run 4 miles in 31 minutes and burn closer to 550 calories

In the end I use the Under Amour App because it has audible ques and whatnot and can classify a ton of different workouts.

But like someone said calories burned is are imperfect. I just use them to track progress and what not. Not as a perfect measurement etc
