Is one tracker more accurate than the other?

Much research suggests that chest straps are considered to be more effective than wrist straps. This is mainly due to the fact that they’re worn closer to your heart and have multiple touch points on the skin.

Does the tracker I use make a difference in the amount of Fiit Points scored in group classes?

Following rigorous testing, we have found both devices to be identical in awarding Fiit Points. Any discrepancies in tracking should only be single-digit variances — which means there will be no disparity with Fiit Points between the trackers (assuming both are worn correctly throughout the class).

Any differences greater than single-digit will be a result of either device not getting an accurate reading due to a particular movement, not as a result of the tracker itself.

This means that there is no advantage of using one tracker over the other in any Fiit class.

How will the difference impact the number of calories burned? 

Each tracker calculates calories burned slightly differently, so even though the recorded heart rate and Fiit Points are identical, there will be a minor disparity with recorded calories burned.

If you are using the Apple Watch, the calories recorded in the app will be the same as shown on the Apple Watch.
