considering I do wear my watch most times of the week, and have my iPhone 6s either in my hands at home (for the most part) or in my pocket when out or on my desk at work. The first week I got the watch 2 weeks ago it said I did 17miles which I was impressed and then just now today the weekly summary says the second week I did 25miles walking. How. Accurate. Are we. Talking. Here. Lol. Thanks!
