Ruh-roh!

I wore my Michael Kors smartwatch to the fitness center this morning to see how accurately it measures steps.

It didn't do very well.

The treadmill said I covered 1.13 miles and burned 100 calories.

But the smartwatch, which had been counting my steps since I got up a few hours earlier, said I only covered .4 miles and burned just 31.4 calories so far today.

That's a pretty significant discrepancy.
