#3 day 21 I for got to put it up yesterday

Samantha Bovee

my husband and I figure it goes by height vs steps. for example  I put in 5'5" and walk 10,000 steps it will say 5 miles while my husband being 6' walking 10,000 steps it will say 7 miles because his leg span would be larger it would cover a larger distance 

i wonder how they guess the distance walked because for me around 10400 shows 5 miles.
