About 1.25mi into it we realized the discrepancy and the gulf between ours just continued to grow as time/distance passed.
Wife and I do this all the time... using MMW... she has an iphone and I have android... we have never had the same miles for the same walk. Usually my phone shows a bit more.
I just went on a deep forest walk with a friend... she had an iphone and MMW... her phone tracked the routed pretty well, my phone choked and showed 1 mile of our over 2 mile walk... it did some straight lines that obviously left the trail. It logged the time right, but blew the track.
