Yesterday for example, according to my phone app, I walked 5.58 miles for a total of 13,190 steps (107 minutes). However, under Activities on fitbit.com it indicates only 8,130 steps (1 hr 38 min). Why such a difference? This is the same sort of difference every day for all my walking which I simply hadn't noticed before. Hopefully my swimming is being recorded correctly on the computer!
