I have considered getting one but my phone has a 'health' app on it; it counts steps, and miles which is basically all I want. It has a lot more information you can use but I just don't. Or because I've not figured out how to use it and then again maybe it has to be connected with an exterior source - like a fit bit or something similar. I just put it in my pocket in the morning and take it out at night; course you have a have some pants/jeans with a pocket. Works great.
