I assume it gets the data from the GPS ? But it could be wrong.
Scivz that's a lot in a short time. Mine is also around the hospital
Numbers don't add up at all.....
16839 steps= 17.99km walked.
19220 steps= 23.93km walked
19481 steps= 19.66km walked
Bin said app, they all bull anyway.
Quick edit....
One normal adult human step is 1 meter.
I imagine that not every step will be the same size
How would an app know what size your step was?
