I'm getting curious after our niece looked at her wrist upon completing our little walk, and told us how far we traveled, how many calories she'd burned, avg heart rate, max heart rate, how many steps were taken, what the overall elevation gain and change were, and some other stuff. Granted, she's got some super apple type thing which I have no interest in but it made me curious about the devices. is there such a thing as a cheap but effective version of something like that? I like the elevation thing given where I am but assume that GPS isn't part of cheap.
What do you have? What does it tell you? How well does it work? How much?
Thanks.
