Versa 3 calories burned vs Wahoo

[SunsetRunner]

Looking for a reasonable explanation of the vast difference between the calories burnt on a Versa 3 vs Wahoo Tickr. HIIT workout 20 minutes long, Wahoo says I burnt 280 calories Versa 3 says 135. I  compared 5 workouts with the same result. The average heart rate is comparable when comparing both devices. Just curious why Versa 3 would show 1/2 the calories burnt when compared to Wahoo

Hi there @SunsetRunner, thanks for stopping by in the Community Forums. Thanks for the details provided in your post, I'll be glad to help you with your inquiry about the calories burned on your Versa 3.

Fitbit devices combine your basal metabolic rate (BMR)—the rate at which you burn calories at rest to maintain vital body functions (including breathing, blood circulation, and heartbeat)—and your activity data to estimate your calories burned. If your device tracks heart rate, your heart-rate data is also included, especially to estimate calories burned during exercise. The number you see on your Fitbit device is your total calories burned for the day.

Your BMR is based on the physical data you entered in to your Fitbit account (height, weight, sex, and age) and accounts for at least half the calories you burn in a day. Because your body burns calories even if you’re asleep or not moving, you see calories burned on your device when you wake up and will notice this number increase throughout the day.

Let me know if you have any questions present.

this doesn't even remotely answer the guy's question. I have the same problem. I do an activity and measured by my fibit it's 1200 calories but the same activity measured by wahoo tickr comes out at 1600 calories. They can't both be right. Heart rates measured are about the same.
