Welt - The smart belt for fashion & health by Samsung

It tracks key health data and provides tips and warnings for your health. First time I've seen a "smart belt".

Did the the makers even consider the negative connotations of naming a belt, "welt"?

Seems neat, but if I have a smart watch, this is not really needed.

What would be smart is if it adjusted its size throughout the day in order to fit perfectly even when you ate a bit too much/are bloated.
