I carried my iPhone and wore my Garmin watch today and did 12,000 Steps .

According to my iPhone I burnt 280 Calories but the Garmin Vivoactive is reporting 900 Calories?

Which one should I believe?

    I would tend to go with the lesser of the two although you probably burned more calories than the 280 stated. The Garmin takes in to account the calories that your body would require (although estimated to an extend) to function normally even at rest as well as incorporating the calories you burned doing your 12,000 steps.

    Good job though.

    VA HR? Always on HR monitoring causes major discrepancies.

    Additionally, Apple health and Garmin Connect use quite different algorithms to estimate activity.

    Thank you. Did not want to risk it so only ate back the 280

    If you're only walking then HR can cause a significant overestimate.

    You're asking whether to trust, for accurate fitness information... a dedicated, time respected running watch manufacturer or a company that sells over priced fashion accessories to gullible people...... hmmmm

    Descisions .....Descisions. ....

    That is a big difference. Keep meticulous track of your calories in, weight, and what you are using for your calories out for a month. 1 pound is about 3500 calories. This is how I know non-HR Garmin devices overestimate for me and that I need to add on calories to the MFP estimate to meet my target and not feel like I'm starving to death.

    Did you mean underestimate?

    Since if they're overestimating, you'd end up with extra calories.

    Just want to understand exactly what your issue is.

    I'm pretty sure my Vivoactive 1(Non-HR) underestimates... and for me, that's ok, because It allows me to be much less precise with my calorie estimation and still lose at a reasonable rate.

    I think it's fair to say that the Garmin entry in the bargain basement end of the market didn't go well. The first generation of VivoSmart wasn't a reliable product. The VivoActive, on the other hand, is a solid entry level piece of kit.

    Wouldn't disagree with your underlying point though.
