This question already has an answer here:

I recently bought an external tracker to track various activity and I wonder, whether I should disable tracking on my iPhone?

E.g. let's say my tracker reports that I made 1000 steps and my iPhone reports that I made 850 steps within same period (carried both devices together). What will be the result score?
