@JMHardin The Samsung numbers seem more accurate in my use of both apps.
I think the Fit app is a lot more sensitive to movement, and seems to count just moving my phone around as steps more often than Samsung Health.
Of course, my watch also picks up my typing when I really get going at my standing desk.
I will also say, your numbers are a lot closer than mine. Sometimes Fit is 2-3x more than SHealth, just from the mobile numbers.
