The Walker With Heart

I have two devices and three algorithms that count my daily steps... (The fitbit died)... An Apple Watch... The iPhone health app... The Fitbit app on the phone... Never do the three agree. I can understand the watch being different from the other two, I don't normally leave it on the desk when I get a coffee, I rarely wander off leaving it on the side.

The next question is should I be bothered?  The scientist in me is, I want to unpick what the difference is and why it's so stark on the same hardware.  But there is a bigger question, how accurat
