I work out every day and would like to just wear the watch, use and app, and get consistent results regarding calorie burn numbers. I do a variety of activities from cardio (Zumba), walking (on hilly terrain which does get my heart rate up quite a bit, e.g. 145 bpm), yoga, and weightlifting. I find that wearing a chest strap (Polar heart rate monitor) combined with iPhone Digifit app gives the most accurate results but I would much rather use my Apple Watch alone and get accurate results. Has anyone had much luck with that?

I find that the Apple Watch alone really short changes me for calorie burn, even if I take into account that it deducts my resting calorie burn and only reports the active part. A workout which reached my target in 1.5 hours now is taking 2+.

I have tried the native fitness app, Motifit app, with a chest strap and without. Digifit and chest strap is the most generous calorie count, Apple Watch alone with its native app gives the stingiest count. Motifit looks like it misjudges my heart rate a lot (e.g. I know I was at about 145 bpm on a workout but it was showing 113...big difference).

I am not looking for scientific accuracy but I am looking for consistency and ballpark estimates without use of the chest strap. Has anything worked for you?
 
OK, here is the latest from the Self Help Desk:

I put on my heart rate monitor and turned it on for a Zumba Class. I also used my Apple Watch activity monitor. At the end of class I racked up about 500 calories on the heart rate monitor chest strap and about 280 on the iPhone. I did this for a couple of days and found pretty much the same correlation and so now I set my Apple Watch daily goal for 280 calories. So far so good. I think I just found my way to make the Apple Watch give me the same credit for working out as the chest strap.
 
Thats a good work around but I would like to see the AW accurate on its own.

When I use a Polar chest strap on the tread mill, the heart rate on the AW is either dead on wth the Polar or no more than -2. I think that is pretty accurate. I have not done any manual calculations to see which device is more accurate but if they are often reporting the same thing or within -2, I'm good.
 
You can try the Under Armour Record app, it does have many kinds os sports and activites and heart rate monitoring as well.
