Wahoo fitness app question

Paxtonite

I'm sitting here wearing my wahoo HRM, and looking at the app, and it says I'm burning at 240cal/hr. that can't be right surely?

My HR is hovering around 70 (my resting HR), but going on the app, I'd burn 6000+ calories over 24 hours.

Am i missing something here?

It makes me wonder if the results of my walks/jogs are incorrect too.
