So I've been wearing my fit bit and using the generic Samsung fit tracker to track how far my 30 week butt has been waddling when I'm at the river or park, bc I like to know this stuff. However there is a good mile difference between the two. The fit bit is always less and idk which is more reliable. they're both on the same arm. The park says the loop is 3/4 mile which would make the Samsung more accurate but even then I feel like it tells me I walk a lot faster than I am and I'm just not sure. Which would you guys go by?
