Calibrate within hardware App or within Zwift?

[Steve_Weeks_STW (Steve)]

Just wondering what people do really ?

I’ve got a Wahoo Kickr Snap and i generally calibrate it about once a month in the Wahoo App and about once a week within Zwift.

But curious as to what option and how often people do theirs ?

I use the Wahoo app because the last few times I tried using Zwift to do a spin-down it failed.
