A:Answer I am not sure about the meters, but there are 2 versions and yes, one is slightly bigger than the other. The new feature is that one you can take on the go without your phone and use as a cell phone as long as you add it to you cell phone provider’s plan. For me, it’s $10 per month with Verizon. The other version you can use without adding to your plan, but it must be close enough to your cell phone to use with bluetooth. I personally prefer the version with cellular so I can take my dog on walks without having to carry my phone. I can also just wear the watch at the gym without having to carry my phone around.
