I was looking at the inspire, for the price, but it doesn't have heart rate. I just started keeping track of my blood pressure and my resting heart rate was 98I really liked my slim Alta one that disappeared.
I would recommend buying any of them.
Just go to their website and use the compare option...
All of them count your steps but only some of them count your activity stuff and only some of them count your sleep.
Those are the only three things I care about but there are many other things that it can keep track of too.
